Info by Big Photos – extension for iOS Photos app.

New Features:

Discover picture fro video:

When you pick a video, Big Photos will launch video player to play the video, if the video is stored in iCloud, it will first download this video, so you will see a spinner for waiting. Once the video is playing, you can pause or fast scroll at your favorite frames, tap select. Then you will be given around 10 frames to choose from. Tap the one you like, or tap the Done button. This picture will be extracted and display on home screen, you can edit or just save it.

Horizontal Photo Selection Scroller:

Crop with locking custom aspect ratio assist. Optimized for with 4” retina display! Support big pictures and large images.

If you find the app behaves very oddly, delete it and reinstall. Things will be OK.
It is because AppStore downloads and installs incorrectly. Small chance, does happen.
To allow access your photo library through Big Photos:
If you are running on iOS 5.x, chances are that you need to go to the device “Settings”=>”Location Services”=>”Big Photos”==>On
If you are running iOS 6, you may need to go to the device “Settings”=>”Privacy”=>”Photos”=>”Big Photos”=>On
Big Photos allows you to view pictures of ANY sizes at full resolution with unlimited zoom in/out and highest quality. Precisely crop with exact coordinates and pixel sizes, with or without locking custom aspect ratio. Accurately enlarge (like digital zoom) or downsize pictures with exact pixel sizes with or without locking aspect ratio. Automatically save your cropped, enlarged or downsized pictures back to your Camera Roll.

Capable of big pictures and large images: iPhone 4S/iPad 2 – 74MP+ for unlimited detail zooming. 56MP+ for resize and crop – sum up the sizes of source and result images. For other devices, adjust the sizes accordingly.

Work as your device’s universal image tool: for images in your emails or other apps, “Open in…” Big Photos to get detailed zoom and edit. Support Import and Export image files through iTunes File Sharing.

Big Photos combination of features extends the capabilities of other great photo apps given its special algorithm to deal with big pictures or large images. It is also an essential tool for iPhone 4/4S/5 not only because of its wonderful zoom viewer, but also you can use crop and enlarge to achieve better results than you use iPhone camera’s real time digital zoom.

★★★★★ “I am thrilled to have this tool. Thank you to the developers of Big Photo.” – HallYoung@Art, USA

“An undiscovered gem of utility” –

★★★★★ “Great app that resizes photos to 200%+ their original size without ruining their quality. Resulting output is similar to that of resizing algorithms in Photoshop. I use this app daily and it always gives me what I want in a timely, stable manner. This app is truly a useful and prized tool in my arsenal of photo apps.” – M., U.S.A

★★★★★ “5 stars for ability to zoom in really close and crop a small portion of a photo in high quality and custom dimensions. The slow and clunky user interface has been fixed in the recent version. It is now a joy to use, and tremendously useful.” – Maria, Greece

★★★★★ “There are a number of creative apps that are really useful but lack decent resolution output. Big Photo does an excellent job or sampling up and making those other apps more creatively useful… For the iPhone camera output and other ordinary camera apps shooting at the standard 8 million pixels the software easily deals with scaling up with great results. A much needed tool for mobile art and photography. Highly recommend.” – Poetry, UK


In addition to access your Camera and existing Photo Library, Big Photo also provides document interaction support so you can launch Big Photo to handle pictures or images from within your other apps that support document interaction.

Better yet, for advanced users, you can transfer your pictures between your PC/Mac and Big Photo’s iTunes File Sharing folder. For instructions how to use iTunes File Sharing, see

Support file formats:png, jpg (jpeg), gif, tif (tiff), bmp, ico, cur, xbm.

1. Photo Selection Scroller

In “Menu Mode” – i.e. when the menu bar is showing,  swipe up/down/left/right, Photo Selection Bar will pull down or fade out.

This Photo Selection Bar is a horizontal scroller to show your Camera Roll or any currently selected photo album. You swipe left or right to scroll through your Camera Roll or any photo album. Tap on any photo icon to select for viewing or editing.

2.Take picture with Big Photo

Tap on Camera Icon, Camera will open for you to take a shot.

3. View pictures of ANY sizes with unlimited zoom

Common touch gestures support on big pictures and large images:

  • Pinch in/out to zoom in and out.
  • Press and Hold on spot,  you will zoom right into the spot with full resolution and 100% zoom.
  • Double tap on the picture, you will zoom right into the spot with full resolution and 100% zoom, or the picture will zoom out to a complete view fit on the screen.
  • Pan left, right, up, down to shift the view port of the picture.

When you have pictures or images over 20 megapixels, most photo apps will work on the downsized versions of those assets. Big Photo will allow you to gradually examine those assets in its original resolutions, up to pixel level.

4. Crop with precision

Big Photo allows you to crop your big pictures in its original resolutions so your cropped pictures will keep much more pixels than you can get by cropping the downsized versions of the big pictures.

5. Accurate Scale – Enlarge or Shrink 

With Big Photo, you can enlarge or scale down your original or cropped pictures to any sizes you like to. The enlarged or downsized pictures will be saved to Camera Roll automatically.

6. Import from or Export to Documents folder

    Can I save, in my photo album, my new enlarged crop image in Big Photo?

  2. greg says:

    I want to look at the photo on the full screen and zoom in full screen. i have … which does this. i also need a way to organize the files – which picflick does not do – which is why i bought your app. If I cannot do this, it defeats my purpose for buying the app. Can I do this (zoom in full screen and organize pictures in the order i want) or get a refund? i dislike the process of having to buy the app to find out if it does what you want.

  3. zynsoft says:

    Dear Greg,
    Big Photo does not lose pixels or resolutions.
    Big Photo has some very unique features like “Press and hold, tap to zoom in the spot”, “Unlimited photo pixel size”, “Precise Crop”, “Precise Resize”. By precise, we mean that you can specify coordinates and size points.

    Regarding your request,
    1. Full screen mode will come in next update.
    2. Organize photos: current Big Photo can save pictures back to Camera Roll automatically. You may organize from there anyway you want.

    If you want Apple to refund your $0.99, it is fine.
    But, be aware that Big Photo has everything it claims to have.

  4. Uwe egert says:

    I am not very good in computing, like your app, but do not knew how to e-mail it or send to camera roll.

    • zynsoft says:

      When you click Crop or Resize, you will see “Crop and Save image …” or “Resize and Save Image…”. Then you click “Open”, select “Camera Roll”, you will see a new image is added to your Camera Roll.

  5. Michael says:

    How to import a 40mp pic into my iPad? It seems to me, that every import resizes the pics to 14mp.
    Nevertheless, your app is a great help for my ‘big’ files.

    • zynsoft says:

      You can use

      Download 2i
      Browser 2go

      Using iTunes file sharing,
      to copy any file of any size from your computer to the app
      either Browser 2Go or Download 2i
      In either app, touch the file, the file will open, then you tap the right top button, click “open in Big Photo”,
      now you can do whatever you want, including save to Camera Roll.

  6. Vicky says:

    I like it!
    An essential app that makes you see the difference!

    The two pictures are great examples.
    Like to get more…

  7. Agathe says:

    what is trashbutton? I tip on photos, ok? then tip on photolibrary, ok? now tip on camera roll, ok? on the top, left, there is the button back to photos, in the middle the name of the tab – camera roll – under this there are all taken photos and films, but there is no more button.
    where can I find the trashbutton, but what have I to do, that trashbutton comes?
    Thank you for supporting me

  8. Simon says:

    The new zoom feature is excellent and a big improvement but if you zoom in too quickly on a 36 MP photo then the view jumps to the bottom right of the image.

    • zynsoft says:

      The reason could be that you touch twice somewhere when
      you zoom, Big Photo then display the part you touched
      in the center of screen.

      Most effective view of picture with big size is double tap on the spot you want to focus. Big Photo will try to show the spot in center of screen with full details.

      With Big Photo, you will find iPhone 4S camera roll picture is much bigger than its version in photo streams.

  9. Jay says:

    Awesome app, thanks!!

    In a future version might we see some controllable aspect ration 4:3, 3:2, 8:6, 6:8, 2:3, 3:4, etc? This will make it easier to crop “standard” photos out of the app.

  10. Simon says:

    I use your app a lot on my iPhone 4S, iOS6. I just noticed something that raises a question. Lets say your app says my picture is 2.98 MB, why does all other source of info (exifwizard, iPhoto, OS finder) say it is only 866 Ko?

    Thank you!


    • zynsoft says:

      The photo info is based on the processed working file from your original image. It is substantially bigger because of using highest quality compression.

      • Ryn says:

        I was wondering the same thing and read this comment. I need my photos to be less than 1 MB. Which file size is accurate? The file size within Big Photo or the file size from other sources?

      • zynsoft says:

        If you are using iOS 6, the file size of Big Photo info is the same as the size in photo library. For some old versions iOS, Big Photo may use temporary file, so it may display the file size of the working file. This is fixed in later Big Photo updates.

  11. Agathe Pupp says:

    I cannot find camera roll any more. If I open big photo, there is on left side: camera, photo, crop, resize and info. There I click on photo, then comes a window: Over all it says: Access Photo with blue background, below Photo library, Import Photo, Export Photo, Earth by NASA. If I click here on Photo library, a window comes and says: This app does not have access to your photos or videos. You can enable access in Privacy Settings. But I don´t know how to do. Where can I find ´privacy settings´?
    Please, would you help me?
    Thank you very much!

    • zynsoft says:

      Go to “Settings” app,
      Tap “Privacy”,
      Tap “Photos”,
      Tap “Big Photo” to “ON”.

      • Agathe Pupp says:

        Ok, but this is my problem! Where can I find “Settings” app? Is it on PC i-tunes – big photo app? but there I also cannot find Settings.
        On my i-Pad app big photo there is also no Settings.
        Or do you mean i-Pad, there on screen settings, there apps on left side, and here seeking the app big photo?
        But here I can find all the apps for example: WLAN, Bluetooth, Messages, iCloud, Mail, iTunes&app Stores, Musik, Videos, Fotos & Kamera, iBooks… and so on, but there is no app big photo.
        I don´t understand where I can find the Settings you mean, being big photo inside.

        Thank you for helping again.

      • zynsoft says:

        Please check email and let us know how you resolve your problem.

  12. KC says:

    Hi. Love your app, but looks like if I take a photo in portrait orientation using the regular camera, then resize it using Buig Photo, the resulting saved image from Big Photo is set to Landscape mode. Any way you can look into this and fix the problem?

  13. liveeyephoto says:

    I got your app and I love it but I have a question. I took photo with the iPhone camera and I took a photo with your app and then I bumped the megapixel on your app thinking it may show more detail then the iPhone photo but no such luck. I printed both photos out and can’t tell a difference. Is this app just for cropping in real close without loosing any pixels or does it add more megapixels to your photos too. The other think is when I take the photo I edited in your app into another it shrinks it way down, I guess because those apps can’t handle anything that size

    Thanks so much

    • zynsoft says:

      Thank you dear customer. There are several things that Big Photo can do:

      1. You can view your photos with full resolution. i.e. see every pixel in your original photos regardless sizes: 5mp (iPad/iphone4), 8mp(iphone4s/5), 28mp(panoroma)… . If you use iOS default photo library viewer, you can only view the downsized version which is not more than 4.75MP.
      With photos you take either by iPhone camera or Big Photo camera, you can view more details with Big Photo than default iOS photo library viewer. The BIGGER the photo, the MORE details you can see with Big Photo.

      2. You can bump the megapixel (enlarge)! After bumping the megapixel, you can check its size by tap “Info”=>”Photo Info”.
      Then, you print it out. Depending on your printer DPI, if your original photo is 4×6, then the bumped up photo could be 8×12 or even bigger.
      Many customers like Big Photo app because the quality of enlarged photo is still very good.

      3. Crop…

  14. Josh Grooms says:

    I use your app for work. I was wondering if it was possible to resize all photos in camera at once instead of resizing one at a time?

  15. egbegb says:

    Can Big Photo use images of maps I store in Dropbox folders?

    • zynsoft says:

      Currently Dropbox for iOS does not support “Document Interaction”, so you are not able to use “Open By Big Photo” function yet (I hope they can do it soon). For now, you can tap “Save to Photo Library”, and Big Photo can handle it from there.

      • egbegb says:

        On my iPad and iPhone, I use DropText (a product of the Dropbox team, I think). When I click on big pictures, I get the usual results of zooming only so far. I’m thinking that is because the iPad viewer is limited. However when viewing such an image I then can open it in about 15 different apps on my iPad including BigPhoto and “save to camera roll”. The big map opens just fine directly on BP and zooms to quality equal to my Mac.

        Try this on you iDevices and verify it. If it is as I say, I suggest putting this quick tip near the top of your forums. I saw a number of questions on how to do this on other sites. Could help sell you product.

        Thank you for the speedy rely.

        Ed Bradford Pflugerville, TX

      • zynsoft says:

        Thank you so much for suggestions. We are highly encouraged by responses from customers like you. We will appreciate that you may put a review/rating on iTunes AppStore.

  16. Jeff perry says:

    It appears that when resizing an image, Big Photo strips most of the EXIF data from the original file. Would it be possible to have a setting that would preserve all the EXIF data in the fille?


  17. Jeff Perry says:

    The new update that includes batch processing is a welcome addition, and I understand the logic of sorting all like-sized images together so as to make batch resizing consistent, but I am at a loss to figure out how the “groups” are sorted? I have over 2000 images on my Camera Roll and even if I know the existing size of the images I want to resize, it is very diffficult to find the group of images with that dimension. If the groups were sorted by dimension at leastit would help. I’m not sure I have a solution, but I thought I would mention it. My work-around is to create an album first and put the group of images into it, then it is easy to find the group.

    Additionally, it would be nice if the batch processor would allow diffferent dimension images to be selected in order to apply a % increase to all selected images. Just an idea. Thanks

    • zynsoft says:

      Hi Jeff,
      Thank you so much for feedback.

      In current update, all photos in selected source photo album will be grouped according to their dimensions/size, then sort by number of photos of the group in descending order. We will think about other possible selectors in future release.

      Regarding your suggestion on selecting photos of different dimensions to process in a single batch, we may support that in future release. The current release is totally for simplicity of UI.

      Best regards,

  18. Donald Schwartz says:

    Question: If I enlarge the picture am I:
    1) Just increasing the number of pixels?
    2) How does this affect the pic resolution?
    Does the printing resolution remain 72 dpi
    3) If the Rez is 72 dpi, how can I up the Rez to
    300 dpi?
    TKU ds

    • zynsoft says:

      If you enlarge a picture using Big Photo,
      1. Picture pixels will increase.
      2. Picture resolution increases
      Dpi unchanged
      3. Print out size will increase with the same printing setting

      If you want to increase print dpi, that means you want the printer to print the picture in smaller size.
      To print out smaller size, you can use Big Photo to downsize the picture without changing DPI.

  19. How do I get the app in batch resize mode. Will rate after this is explained.

    • zynsoft says:

      If you are running on iOS 6.0+, then you will see “Batch Resizer” menu item when tap “Photo” button. Tap on “Batch Resizer”, you will begin the process.

  20. egbegb says:

    One other issue I have with BP.
    I open an image in BP and zoom in without issues. Move to another part
    of the image, and
    apparently BP has limits beyond which it degenerates into traditional blurry
    Apple presentations. That happens both on iPhone and iPad. I have not discovered
    a way to zoom into the high definition corners of my maps. I would very much
    prefer a color pinwheel for 30 seconds to what I get today, which is nothing. If your
    programmers don’t understand or agree, please cause them to offer this
    as an option.

    • zynsoft says:

      The way to get high resolution zoom anywhere: select a photo, once it finished loading, “double tap” ON the spot you want a clear view, BP will zoom right into that spot with full resolution. Then use “pinch” to adjust zoom level. Try to play with “double tap” gesture, in addition to “pinch” and “pan”. Please tell us if this helps.

      • egbegb says:

        Double tap works fine unless I want to double tap on Houston, TX and follow a railroad line to Llano,TX. Pan and refocus would be much better. GoogleEarth does that.

        Thank you for the response.

    • Brice says:

      I agree, this is the biggest problem with Big Photo. If you double-tap, it only shows that one tile in high resolution, but if you scroll, everything else is blurry. It should load the tiles in high-res as you scroll. There is another app out there that does this perfectly. I’d like to rank Big Photo higher in my online review, but this problem keeps the rating lower, and I end up using that other app instead even though the overall features are better in Big Photo..

  21. TinaInVA says:

    Among the many attributes of Big Photo, one I love is that photos that I view in BP display all the information about that photo in ‘i’, or the information panel. As I try many photo apps, I can’t remember what app I used to take a picture. Big Photo tells me, along with a bunch of other photo information [is that what EXIF means?]. This helps identify how camera and photo editing apps behave [app name, size, clarity, etc] as I delete the inferior cheesy apps.
    When I offload my devices [iPad, iPhone] to my Mac, I sure would love the same ‘read’ capability, and even some of the editing too, since device apps are simpler – I’ll never figure out Photoshop LOL.
    Also because I’m not so good at this resizing thing [I tried in Photoshop and failed miserably], I wonder if you could fit ‘FB cover’ and ‘Flickr cover’ in the displayed description of the resize choices. For dummies like me, this would be a selling point in your description: Create Facebook covers, Flickr covers, Instasize photos easily with Big Photo”.
    [After the massive site changes there, the Flickr cover requirements are a mystery even to the Flickr staff apparently, so if you figure that out successfully, there are a bunch of mad Flickr users that you will delight LOL. I tried to resize, even following descriptions on blogs of camera buffs and all I can see in my Flickr cover are belly buttons in a gigantic picture. *scream*]
    Thanks for Big Photo!!!

  22. Peterpeter says:

    New to this app, I have encountered several problems. I need some help.

    I am unable to load TIF image file if it is in the portrait orientation. The image does not show on the screen but the image in four are all available. TIF file in landscape mode seems to work fine.

    On Cropping, if I choose a particular aspect ratio and have it locked,
    the frame anchors can all still move freely as if there is no aspect ratio fixed at all.

    When working on TIF files, when I execute either a rotation or flipping, the app will quit.

    Lastly, most of the files I am using this app on are TIF files, in addition to making this app more compatible with TIF files, it will be very nice that TIF files be offered as an option on saving as well. Or, at least the file to be saved after resizing will remain as the same original file type.

    Thank you

  23. Peter says:

    Can you consider taking App Setting out of “Info” button. In order to actually look at file info, users have to do an extra tap. Can you separate app setting out since most users, at least I, may configure setting only one time but I do look at file metadata a lot more often. Thank you.

  24. Jeff says:

    I really appreciate the app’s capabilities, as there is nothin gels comparable in a single app in the AppStore.

    I do have some suggestions about the cropping function. Once the crop dimensions in pixels is set, the user should be able to move the crop box around by sliding, not having to enter obscure starting pixel points. I waste a lot of time trying to position the fixed aspect ratio crop box I need. Also I can’t seem to understand the “loc” and aspect ratio function. It doesn’t seem to do anything, the crop box’s “corners can still be moved in any aspect ratio when the switch is in the locked position.

  25. Srtevo says:

    Hi there! I just downloaded this app and have a basic question. I take my pictures with a high resolution setting in my DSLR camera. From there, I upload them to my iPad to edit. I was trying to use Big Photo to resize the images to a higher resolution to email to my customers for printing but when I save the resized images to my camera roll for emailing, they seem to downsize back to the smaller resolution. Am I missing something? Thanks so much!

  26. rkarel says:

    Is there a way to edit a photo and then scroll directly to the next on the roll or library without having to go back to library?

  27. Simon says:

    Great app and well done. Is it possible to set up a batch convert on images so that I Cut the top 10% off each image but leave the rest. Or can I crop the bottom 10% only and leave the rest and do this in a batch convert? From what I can see the batch converts are proportional only ?

    • zynsoft says:

      The batch resize does not have to be proportional. You may experiment with any custom size. However, the image may be distorted to fit in that size.
      The idea of combining crop with resize in batch mode like you mentioned, we have explored that. Because only a few customers need that, also complicated for average customers, so these options are not in the batch resizer.

  28. Daniel Solfrizzi says:

    I wanted to download the app. But I realized that it requires iOS 7.1 [ I have an iPad mini2 Retina with iOS 7.06 means that I cannot download it? ] is true?
    Many thanks

  29. Jeff Perry says:

    Idea for a new feature. Please add a feature to “square up” a rectangular image by adding borders to the edges so that the image retains its original resolution (of the long side). Photoshop allows you to do this with the crop tool by reverse cropping and extending the crop box outside the original image. All the apps out there that do that (usually designed for posting to Instagram) downsample the hi-red image to some ridiculously low resolution.

    • zynsoft says:

      Sounds a like good idea. But does anyone need this?

      • Jeff Perry says:

        Anyone who posts to Instagram could benefit since Instagram forces a square crop, thus losing part of your rectangular image. There are a lot of apps available to do this, but almost all downsample the image in the process to some ridiculously low social-media resolution. I don’t post to Instagram, but do have a bunch of photo editing apps the force a square crop when loading an image, again forcing me to crop away part of my image. So squaring up the image first, at full resolution would allow me to load the entire image into the other apps for processing without losing any of my image. I could then crop away the extra space later.

        Thanks for responding.

      • zynsoft says:

        Great feedback! When square UP the image, do you think the two padding rectangles should be transparent or have solid color (e.g. white or black)? Probably solid color will be less confusing for average users?

  30. Hi BigPhoto people. I really love this app, it’s really useful. I have a need to make the white in an image to be transparent. I see that in “settings” it give you the option of saving the alpha… How do you specify what you want to be the Alpha?

    • zynsoft says:

      “Save Alpha” On ==> meaning you want that PNG file and rotated image to keep their transparent portion when resize/crop/rotate. Please note this option will consume more memory/storage.

  31. Please verify that batch resize no longer works once iPad / iPhone upgraded to iCloud a Photo Library

  32. Jnhphoto says:

    How do I export this to my Mac for printing

  33. Larry Zasitko says:

    With the recent update to iOS 9 Bigphoto still works good but when my iPad is in landscape orientation the menu/keyboard remain in portrait orientation. Can this be fixed a sap please.

    • zynsoft says:

      Hi Larry, we understand your preference. Some users also want to have the menu keeping at the bottom. We may refine this next version. Actually we have it on the left for some version. But on iPad pro…

  34. xxx says:

    Fabulous, what a blog it is! This weblog provides helpful facts to us, keep it up.

  35. James says:

    I want to use Big Photo to change dpi from 72 to 300 for printing. When I try to do this the size of the file in megabytes reduces dramatically from say 2mb to 800kb. How can I maintain full resolution as I am merely rearranging the pixels not deleting or adding them. Thanks.

  36. Petter Uren says:

    It works as intended.
    I will not give it full score because the two tap zoom only goes to 100%. Ideally it should be possible to set the magnification rate in % in a preset function so that the magnification was able to match my magnification glass.
    The other thing missing in the app, is the ability to preset where on the screen the double tap zoom window should show up. As it is now, the zoom window almost cover the part of the photo I am zooming in on. I want to be able to see both the zoomed in part of the photo, and the original part of the photo at the same time.
    Another missing feature is the ability to preset the size of the zoom window in %.
    With those features added, I would have paid 500 usd. for the app.
    I use the app to look at photos while painting and drawing.

    I have 6,200 pictures on my iPad running the latest OS and using the latest Big Photo and my pictures when I select Photos->Camera Roll are no longer sorted correctly by date. There are pictures a few years old interspersed with pics I took today. I looked at the meta data and the dates are accurate but the sort is not working correctly. Thank you!

      Hi Tim, this issue is due to iPhone sync your photos from iCloud, so it is possible many old photos are created after some newer photos. We will see if we can sort by original taken time if these information available.

    Hi there, can I connect the Big Photo app to Google photos so that I can access my Google Photo images directly on the Big Photo app on my IPad? Love the app by the way. Thanks!

      For now, you may be able to selected multiple photos from other apps, use “Open in Big Photo” to process. However, the results will be saved to iOS camera roll.

    I do not want to give you unlimited access to my photo library. Please ASAP…
    1.How do I delete this?

    2. How do I just download one photo only?

    3. I DO NOT want to crop my IPhone image.
    I just want to bring quality to my existing sized photos. Can this be done?

    Change the DPI’s
    And be able to print a bad resolution IPhone image, like 60KB into a good 24”x24” print? Or is this the wrong software?

    Do you have customer service phone
    contact? Send number please.

      Big Photo app is not sending any picture data to server so far. So everything is private. We only have feature usage counters. No personal information is collected.

      • zynsoft says:

        You may use “Open in Big Photo” with iOS Photos app, then Big Photo won’t need to access your library. However, in case you create new photo with Big Photo, saving back to Camera roll will cause error if you don’t allow access to it. In that case, you can only use “Export Photo” to save the app’s documents directory. Then you need iTunes file sharing to get it from the app’s documents directory. Very techie.

    Super newbe here. It looks like you have some basic resizing programed in to the app, but not 4×6 or 6×4. Can you add that, or tell me how to manually crop images to that size?

  42. Susan Anderson says:

    I purchased this app at the suggestion of iPhone Photo Academy because I sent a photo to Shutterfly to make a 20×30 canvas print. They replied that the resolution was too low. I don’t understand how to change the resolution using your app. Is there a more re thorough tutorial available? It can you instruct me?

    • zynsoft says:

      You can use “Resize”, then enter DPI field (the printer resolution, e.g. 300) first. Big Photo will show the print size inchxinch in real time when adjust target resolution by sliding or manually input.

    Resized 8 images with basic batch resizer, saved to folder (love this feature) but there are 14 images in the folder not 8 and the duplicates are super soft. Why the duplicates and why are they so soft? (Most have a sharp correctly sized image with the dupe.) Never had this happen using the individual resize. All were from 9 megapixel sharp originals resized to FB ad specs 1080×1080. Also resized a single image using batch to automate putting it in the folder and it is also super soft, but no sharp “duplicate”. Suggestions? Running iOS 12 most recent Beta.

    • zynsoft says:

      Thanks for feedback. We identified similar problem. This is caused by photos stored on cloud, not available on your device. The iOS SDK called back with a low quality first, then called back with the downloaded photo from cloud. In your case, we suspect that both low quality and high quality photo are used by Batch Resizer. We will release a fix soon. Should be within this week.

  44. Marsha says:

    Wish list: remove location meta data, edit IPTC to include ©️ in both individual and batch resize.

    The most recent update for iOS breaks the Photos extension. “No Image Available” IOS 13.1.1, iPad Pro 10.5

    Currently BigPicture allows export to only PNG-8 format that has an advantage of a very small file size but is absolutely unusable for professional post-development. Even 8-bit TIFF would allow to use such enlarged images in professional practice.

    I purchased BigPicture because no other alternative for iOS. Add export to 8-bit TIFF and 16-bit TIFF please. Optionally it can be PNG-24. Otherwise I would have no a possibility to use the purchased software.

    iOS is not a toy but a serious environment for migration of many photographers in the moment.

    I hope on your understanding this simplest requirement of a pro-grade photographer who likes to move the complete workflow to iPad.

    Thank you in advance – Dmitri

    Big photo is messed up. The resize window used to be black. Now it’s clear/white! We can’t see the settings!!! Please fix ASAP. I’m available to beta test if needed. Message me
