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.

I am glad you found this app. The lossless JPEG transformation is not a new technology. It was known by a part of PC user. There were many lossless editor for Windows and Unix. But strangely there are not such app for Android. So I developed. I hope this app become one of the choice of picture editor for many Android user.

This is =almost= just what I want. For example, my screen is 3:4, and a lot of available wallpapers are 9:16. This app lets you set aspect ratios, which LLCrop does not. But when I select 3:4, the crop rectangle often does not include quite the full width, and there seems to be no way to get it. Also, the changes in size proceed in jumps, not smoothly. I thought you couldn't slide the rectangle down, but then I read in the long description about the long press. I'm hoping for an update!

Technically, lossless cropping can only be done on a block-by-block basis. So currently this app can not crop freely. But when without rotation and flip, it might be able techinally. I will consider to imply the function. Please wait patiently.

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!

Better JPEG is great work. It can perform various lossless operations. On the other hand, this app can only perform simple and commonly used operations. But the limitation might make this app easy to use, I believe. I am glad that the app meets your requirements.

What's new

Added a new operation, 'Pixelate'.
You can pixelate up to 16 areas.
