It's a great app. There's one unclear design element IMO: after a batch compression, one might expect "delete" to delete the originals, rather than the brand new files. Having a "delete originals" option would be nice (different from Replace, allowing an inbox > outbox workflow.)
Love this app! Now i can reduce the quality to either send over discord where size needs to be lower, or so that i can preserve the high res myself and send low res to my friends so they cant steal my original work. Best thing is that you have full control, and can choose multiple images at once. Perfect!
The best thing about this app is its various options to have an output with a designated file size with a pre-image for our reference, while keeping a not-too-bad quality even at a very small size. Many other similar apps do not offer so many options. Highly recommended.
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.
