User reviews

Stopped working

Used to be great, but stopped working with the major update. Now it always shows me the same small selection of photos, no matter how many I give it permission to access.

Response from developer

In that case delete it and reinstall. It will fix the problem

Rebuilt App removes old functionality entirely

I loved the old Kompressor app because it let me compress any image. The new app only allows RAW compression. Some of my HEIC images might be 3MB and before I could easily bulk shrink them to under 1MB. This is now impossible.

Response from developer

I’m sorry that you are disappointed, i’ll try to add that back in a future release.

Excellent app!

I’ve had this app for several years and it works great! Does exactly what it says it does. Even after compressing and then making changes to photo, you can compress again. It May not be much but every little bit helps!! It’s never bugged out or glitched on me. Very reliable!! Thank you!!!

Really Convinient

No ads or anything, no sign up, just straight up decompression. I wish you could decompress videos though.
