doesn’t allow you to choose the size u want to reduce….compresses randomly
Simple yet get the things done . Keep doing the good work
crashes every time i try to even use it ur app sucks
Easy and free
No indication of in app purchase but £29 to be paid immediately before use
For a free application, this one is not only functional, but it has many hidden features.
It straight up doubled the size of my pdf. Sketchy af and full of ads. Other reviews must be fake because this app does NOT work.
Trying to compress a 2.7meg PDF and it made it 3.5 megs!
Please, this thing in overrun by ads. EVERY time you compress anything you must close out the app - re-open it to get to see what you’ve compressed! Ugh! And it even made one file I had BIGGER!!! What???
Don’t download it
There should be no reason why it’s only letting me compress one document and it just glitches and exits the app everytime I try to do a second one. Unacceptable!
Disgusting and waste time no compress
Had a really dodgy ad that was asking for malicious permissions
This app increases the size instead of compression
Compressed my PDF of less Kb into more MB format LOL
I rly needed something fast and easy and this did the trick!
After compression 800kb made 1.6mb
Best Best Best
It’s exactly what I was looking for.
It's not working anymore from 4/09/2025
