Great app, thank you for making this! Is it possible to have the sorting selection be retained? Every time, I have to change "sort by modified" because it resets to "sort by name". Also, in all the months (over a year?) that I've used it, I had no idea there were other buttons along the bottom. I wondered why there was no "settings" option. Could you set the scroll bar to be always on, or some other UI indicator which makes it blatantly apparent that there are other hidden buttons?

Thank you for your report. Unfortunately, the file selector is not part of the app. The app only calls the system to execute the file selector. The file selector is implemented by each smartphone manufacturer. We recommend that you choose a smartphone from a manufacturer that focuses on ease of use. Sorry for the inconvenience.

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 exactly what I was looking for. It's a truly lossless jpg edit. Thank you very much. Just wonder if it is possible to enhance it to: 1. Update the thumbnail of the output pic. 2. Output to the original folder. 3. Allow adjustment of the brightness etc. Update : Perfect implementation of color adjustments. Thank you very much!
