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.)
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.
I don't know about ads, since I'm using root+AdAway, but the ad free experience is SOOOO great. the app is perfect without ads. like paradise. Very well done devs. now, I know your revenue comes form ads, but I'm new to rooting, and I want to take full advantage of root! this includes eliminating ads! Anyway, 10/10!
The best one compressor. Thanks You So Much, the whole team of the app development, may God bless you. I recommend this app as the best image compressor on all other apps. All the prayers for all of you.
