Ratings and reviews

Aside from not preserving file modification date and not having a batch function (i.e. select multiples photos, apply same effects to multiple photos, etc), this is the best lossless rotation app ... bar none. it does not upload photos to servers (i.e. the app does the grunt work). it does not mess up exif info (which, for example, "LL CROP" app does). Interface is old-school but when the app is this good, looks are just a minor issue. Plus it's free and there are no ads (hope it stays that way)

This is excellent. I've been waiting so long for an app like this! I use the BetterJpeg program on Windows and Llcrops on Android is also good, but missing grayscale conversion and fixed aspect ratios, now I've got everything in one, compact app. Well done! The more you look into this app, the better it gets! Just found that you can zoom during crop by doing a double tap on the region outside of the grid. Loving it! Now more features! Well done. :-)

This actually performs lossless operations on jpegs, I had to run a test myself because of how rare it is to see an image editor to do the right thing. The interface is clean and simple, It's also free! The ability to perform some image manipulations without reducing the quality is something that every app should support. I think it's sad that most people keep taking quality hits on their photos each time they edit them or upload to certain sites not realizing how each time it recompresses and reduces the quality.

What’s new

Fixed the problem that pixelation preview is not correct on Google Pixel.
Modified pixelation interface. You can now select a pixelation rectangle with tapping it.
