Excellent app. Not so many ads. Does a good job. Other apps are practically useless due to overwhelming ads or stupidly priced weekly/monthly/yearly subscription fees. Aps in general on Play Store are getting more ridiculous to try and use because of this, so it's good to find a decent app to use.
Spectacular app, problem is I think that it should compress images equally, so if you mark images of absolutely different sizes the out put should be similar for all images (not that it compresses a 15kb image further)
I particularly like the manual compression to 50kb as it is not a noticeable loss of detail on my tablet, yet it removes a great deal of unnecessary space bytes. I think it also gets rid of the meta data be default and who knows what be lurking in there.
Have been using this App on a Pixel 8a for about six months. The 8a does not offer the option to change the resolution. I like the large files the 8a captures including RAW mode but, I need the option to send smaller files via text to clients and this app has been a life saver. It is worth the one time purchase price. A+++
