Ream
Every PDF tool. All of them offline.
Merge, split, compress, sign and protect PDFs entirely on your phone. Ream has no internet permission at all, so it cannot send your documents anywhere.

Why Ream
Built the other way round
Most PDF tools upload your file to a server and do the work there. Contracts, bank statements, medical records, identity documents — the things people most often need to merge or protect are exactly the things that should not be sent to a stranger's computer.
⬡
Everything on device
Every operation runs on your phone. There is no server to upload to, because the app has no way to reach one.
◈
Your original is safe
No tool ever writes to the file you picked. Each one produces a new file, checked before you are offered it.
◎
Eleven tools
Merge, split, reorder, convert, compress, protect, unlock, sign, watermark and number — one app, not ten.
✦
No account, no ads
Nothing to sign up for, nothing to subscribe to, no advertising and no analytics SDK anywhere in the build.
◑
Honest about limits
When a file cannot be handled properly, Ream says so plainly instead of quietly producing something broken.
◐
Small and quick
A 7 MB download with no background services. It starts, does the job, and gets out of the way.
How it works
Three steps, no waiting on a server
1
Pick a tool
Open Ream and choose the verb you came for — merge, split, sign, compress.
2
Choose your files
Android's own file picker hands over just the documents you select, for just that job.
3
Save or share
The result waits inside the app until you decide where it goes. Or delete it and nothing remains.

Privacy
Ream has no internet access
Not “we won’t upload your files” — Ream cannot.
An Android app can only go online if it asks for internet permission. Ream never asks for it, so your phone blocks any connection the app could try to make. That means you don’t have to take our word for it: open Settings → Apps → Ream → Permissions and you will see no internet access listed.
- No internet access
- No storage permission — files come through the system picker
- No account, no sign-in
- No analytics, telemetry or crash reporting
- No advertising and no advertising identifiers
Your original file is never modified: every tool writes a new one. Read the full privacy policy or the terms of service.
FAQ
Good to know
How do I know it really doesn't upload anything?
You can check it yourself. Open Android Settings → Apps → Ream → Permissions. There is no network access listed, because the app does not declare the INTERNET permission. Android will not open a network connection for an app that has not asked for one, so this is enforced by your phone rather than promised by us.
Does it need access to my files?
No storage permission at all. You pick documents through Android's own file picker, which grants access to that one file for that one job. Ream cannot browse your storage or open anything you did not hand it.
Is it free? Is there a catch?
It is free, with no subscription, no in-app purchases, no advertising and no account. There is nothing to upsell because there is no paid tier.
Can it recover a password I have forgotten?
No. Remove password works only when you can already open the file. Ream does not guess or crack passwords, and no honest tool can.
Is the Sign tool a legal digital signature?
No, and the app says so before you use it. Sign places a picture of your handwritten signature on the page. It is not a certificate-based digital signature and does not cryptographically prove who signed.
Are there files it will not open?
A few. XFA forms — used by some bank and government documents — are refused rather than silently emptied, because their contents cannot be preserved. Certificate-encrypted PDFs are out of scope for now. In both cases Ream tells you why instead of producing a broken file.
