***** "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

UNLIMITED ZOOM! Best photo viewer

Vermont attorney

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!

Ok You Got Me


I don't like writing reviews unless i really really mean it, good or bad. When i opened this app, you prompted me for a review. Ugh. And then i stopped. I used this app because i needed a specific crop size and you are one of the few apps that can do it, and you do it quick and easy. So to keep myself an honest woman, i am here to say you are a best in class--perfection in what you do. You are always on my iPad, even after I have installed and deleted hundreds of photo and paint apps and tools. Thank you for a great little tool!

An excellent app


This is an excellent tool to increase the pixels in a photo especially before editing. I was not aware of the app until I joined an online photo group. Those members whose posts always grabbed my attention touted Big Photo. I quickly saw why when I started using the app. I am an amateur photographer but Big Photo has enabled me to achieve truer edits. It is very easy to use and I have not had any problems with it in over a year of use.
