I love this app, the compression is good as the compressed output file sizes are small, of good quality, and are small fractions of their original size. The overwrite original file feature - replaces the larger original file with the smaller compressed file if you want to - is a game changer. Compresses photos & videos with the same app. You may also compress many files at once: I have compressed 70 photos at once; pretty sure more can be done, I just haven't tried. VERY USEFUL HIGHLY RECOMMEND.
I couldn't get the app to work at first, but Piers was very communicative & helpful. Once I figured out there was a permission I needed to allow for the app to access my photos, it worked well. It's definitely worth the one-time fee to get rid of ads, too.
Edit- I see. I am updating my rating, but I wish app description was clearer about the fact that it only converts to jpg. Also the location of compressed image should have been clearer. It was the smallest text and in white colour. I completely missed it before.
Masterpice deserves 5 stars. you can do batch all i juat did 1775 pictures at once without selecting one by one and the quality is amaging. you can adjust the quality hiw ever you want. Thanks to the owner & developers <3 .
