Doesn’t work on my IPad Pro

I have a 2025 IPad Pro and this app does not work at all. It’s fine on my iPhone but I can’t get it to open any files.

Good compressor app for PDF

Free or pay $5 AUD to remove ads, done

Best Compression & Quality

This app is by far the best app to use to compress large PDF files that can be reduced in size to under 5 MBs or less. Outstanding!

Is the document safe?

I am wondering If I may use this app. Are those documents? Are they permanently deleted?

No longer works with current iOS update

No longer works with the current iOS update. This app should be removed from the App Store.

Amazing

This app is a life saver. Amazing!

Great app!

This app does exactly what it says that it does, quickly, and for free. The ads are a little annoying, but they don’t last very long. I use this to compress textbooks so I can flip through the pages faster.

Ótimo!

Esse é top mesmo, resolveu meu problema.

Not usefull

Zero doesn’t help😒

It’s caught in a loop

まあ

PCを持っていないのでスマホとかでもPDF圧縮できるアプリあって助かりました。
全部外国語でめちゃくちゃ不安だし情報とか抜き取られたりしても自己責任ですけど。

This app doesn’t work

This app doesn’t work. I download it and it doesn’t do anything. It won’t even open up a file anywhere, much less compress anything. What is the point of this app if it can’t even open up a file?

Good works

The App is very effective

Not working iPad Pro

Not working at all unfortunately, like some of the other reviews there’s no way to upload anything it’s like the select pdf button is not responsive whatsoever. It may work for you, idk try it out.

圧縮するためになぜかインターネット接続を要求される

PDFを圧縮するだけなのになぜかネット接続を要求されて、接続していないと機能が使えないようになってる。
圧縮アプリの中には勝手にアップロードするアプリもあるため、警戒して機内モードで試して良かった。
セキュリティ上、まったく安全じゃないのでおすすめしません。
