***** "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

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

UNLIMITED ZOOM! Best photo viewer

This superb photo viewing app allows you to zoom all the way into your photos - to the pixel level. I have not found any other photo viewer that allows users to zoom in as much. And, this app has never crashed during years of use (other apps limit zooming, by claiming the app will crash - nonsense). "Big Photo" makes for a huge improvement when looking closely at images.

Additionally, this developer cares about their users; they make improvements as needed to ensure a flawless experience!

Great app!

I use this daily. It is a must have if you edit any photos on any iDevice. It has the best cropping and resizing tools. Period. All of this without losing quality of the photo. It can handle very large resolution as well. I edit all of my husband's photo's taken with his Nikon. The app is very stable and has a simple interface to use. I cannot recommend this enough!!!

Sorry, my mistake. Great app

I confused this great app with a bad one. Big Photo does exactly what I needed - made a huge Google Maps image from several overlapping views. Big Photo lets me pinch and swipe to my hearts content. It's about 4k x 1800 pixels. I can see everything down to 1:1. Big Photo is perfect for viewing big photos.
