One toolkit, three ways

Use it where the document is

The same private-by-design toolkit, shaped for each platform — and one optional Premium that works across all three.

Orb2Bit PDF for Windows Free download

The deepest version. Everything the browser does, plus in-place text editing, certificate signing, Office-to-PDF through your installed Office, batch processing, version history that keeps a snapshot before every overwrite — and it all works fully offline.

Windows app

Orb2Bit PDF for Android Google Play

The toolkit rebuilt natively for your phone: scan paper with the camera, make scans searchable with OCR, split, merge, edit, sign, convert and protect — plus read-aloud and night mode. All offline, nothing uploaded.

Android app

Orb2Bit PDF Web No install

Eighteen tools on any Mac, PC, Chromebook or phone — nothing to install and nothing uploaded. Your PDF is opened, changed and saved by your own browser, so it works for contracts, statements and scans of your ID.

Why Orb2Bit PDF

Private by design, not by promise

Most “free online PDF” sites upload your document to their server and hand back a link. Ours don't — and that changes what you can safely do with them.

Nothing is uploaded

Contracts, payslips, medical letters, ID scans — they are processed by your own browser or your own PC and phone, never on someone else's server.

No queue, no waiting

There is no upload bar and no “your file is ready” email. The work happens at native speed on your device, even on a slow connection.

Genuinely free

Every tool works without an account and without watermarks. Premium exists for heavy use, and one subscription covers Windows, Android and the web.

Get Orb2Bit PDF on your device

The same toolkit, three ways — and fully offline on Windows and Android, so a document never needs a connection at all.
