The PDF editor for Android
The official PDF Pro mobile app. View, annotate, sign, fill forms, convert, compress, merge and organise PDFs right on your phone — files are processed on your device, and it's free on Google Play.
Your documents stay on your phone
PDF Pro for Android is built privacy-first. Core PDF work happens on your device — files are not uploaded for viewing, editing, signing or organising. The app only reaches the internet when you explicitly run an AI workflow.
On-device privacy
Your PDFs are processed on your phone for the core tools. Editing, signing, compressing and organising don't send your files anywhere.
Works without a connection
On a flight, the metro, or with no signal — the core PDF tools keep working. AI features simply reconnect when you're online again.
Fast, no upload wait
Skip the upload-process-download roundtrip. Compress a scan, fill a form or merge files and see the result without waiting on a server.
Your data, your rules
No document fingerprints, no analytics on your files, no third-party hosting. Sensitive contracts, scans and forms stay on the phone you control.

Questions about the Android app
Is PDF Pro for Android free?
Yes. PDF Pro is free to install from Google Play. The core PDF tools — view, annotate, sign, fill forms, convert, compress, merge, split and organise — are free to use with no signup required. AI features follow the same free plan and Pro quotas as the web app.
Do my files get uploaded?
No. PDF Pro is privacy-first. Your PDFs are processed on your device for the core tools — viewing, annotating, signing, filling forms, converting, compressing, merging and splitting. Only AI workflows that need a language model send content online when you explicitly run them.
What can the app do?
It's a complete PDF toolkit for your phone: view and read PDFs, annotate, sign, fill in forms, convert to and from other formats, compress to reduce file size, and merge, split and organise pages. AI Chat, Summarize and Translate are available as online features.
Do I need an account?
No account is needed for the core PDF tools — install the app and start working straight away. You only sign in if you want to use AI features or sync your Pro plan across the web app and your phone.
Does it work offline?
Yes. The core PDF tools work without an internet connection because files are processed on the device. You can view, annotate, sign, fill forms, compress, merge and split PDFs offline. Only AI features that require a language model need to be online.
How do I install PDF Pro for Android?
