Doesn’t work.

Drag pdf. Load through Menu. Nothing. Doesn’t work. Garbage waste of money.

Simple & Effective

I use this app all the time on PNG files from 2K - 200K. Easy to install. Easy to use. Never fails me. Highly recommended.

Developer Response ,

Thanks a lot for the kind words! ,

less than 1kb of savings on a 233kb file.

I don't know about applications with 300 meg pngs containing 3D animation, but for real life scenarios I have yet to get any compression whatsoever out of this app.
