4dots Free PDF Compress reviews

I think 4dots has great potential. It does compress files, which is a plus, but the interface is a bit clunky. I’m not sure it’s the most reliable option out there. Hopefully, future updates will improve it!

OMG! This app saved my life! I had a HUGE document for school, and it was way too big to upload. With just a few taps, it was compressed! So easy to use, I can't even! I tell everyone about it!
