***** "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." - T.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... A much needed tool for mobile art and photography. Highly recommend." - Poetry, UK

***** "This is an essential app for viewing photos and artwork. The ability to zoom to the pixel level makes this a great improvement over other viewers. The latest version allows users to navigate icons for photos on the iPad and to scroll from one photo to the in view mode. Thanks - now buy this app, it is a bargain and it works great." - Vermont attorney, USA

***** "I am thrilled to have this tool. Thank you to the developers of Big Photo." - HallYoung@Art, USA

Take a challenge

Big Photo is about to address image/photo resolution limitation on iOS devices. With the latest version, it allows you to zoom and scroll images in full resolution, with pretty good sizes - 91mp for iPhone 4S or iPad 2, over 100mp for iPhone 5/5c/5s or retina iPad.

The app provides a set of useful functions - resize, crop, rotate on the original photos. Its batch resizer is very handy to produce photos with designated size quickly.


This app is the only one I have remaining for resizing. Never crashes and my artwork and photos turns out great! I have noticed that I have more freedom in other editing apps because I have this app to fix my resolution. The developers really have it with this one. Thanks! Thumbs up and six stars if I could. . .

Great! Zoom in all the way!!!!!

Perfect for seeing what's up with your pix!!! Take a close look by zooming way in & have a look at your exif info. Used this to fix a problem my dad had with an email client lowering the dpi of sent photos.

Cropping feature works very well.
