How to use PDF Unlock: Remove Password & Restrictions from PDF

Download the unlocked copy — <name>-unlocked.pdf — and use it anywhere.

When it comes in handy

A bank statement or invoice that asks for a password every time you open it.
A report you are allowed to use but cannot print or copy text from.

Works on any page, without clicking

Hovering any PDF link shows a «🔓 Unlock» badge; an embedded PDF viewer gets an «Unlock this PDF» button. The popup offers the same for a PDF open in the current tab. Toggle in the popup.

Questions

Can it crack a password I don't know?

No. It removes a password you can enter and restriction flags on files that already open. Guessing passwords is not what it does.

Are my files uploaded to a server?

Never. Decryption runs locally with the PDF standard security handler; close the tab and nothing remains.

Is PDF Unlock: Remove Password & Restrictions from PDF free?

Yes — the free tier covers 3 files per installation with every feature. If you need more, Pro removes the limit; one Pro works in all our extensions.

What is Pro?

A single optional subscription ($5.49/month, $35.79/year or $49.99 once) that removes the free limits in every extension of the collection. You only see it when you hit a limit.

Does it collect or send my data?

It works inside the pages you open, in your browser; there is no account and no analytics. The permissions above are the full list.

Does it work in Edge, Brave, Opera?

Yes, any Chromium browser installs extensions from the Chrome Web Store.

Technical details and permissions

The extension asks only for what the feature needs:

Permission	Why
`storage`	Remember your settings locally.
`identity`
`Site access`	The extension needs access to pages to do its job (see the table); it does not send page content anywhere.

Everything runs locally in the browser tab; files are never uploaded.

What it does

Removes the open password from a PDF you know the password for (user or owner password both work).
Removes owner restrictions (no printing, copying, editing, annotating, form filling, assembling, accessibility extraction) from PDFs that open without a password — leave the password field empty.
Reports the encryption method (RC4 40/128-bit, AES-128, AES-256) and which restrictions were removed; downloads <name>-unlocked.pdf. Several files at once, drag-and-drop or paste.

How

shared/unlock.js implements the PDF standard security handler (ISO 32000-1 §7.6 and ISO 32000-2 for revision 6): key derivation for R2–R4 (MD5/RC4, shared/crypto.js) and R5/R6 (SHA-256/384/512 + AES-256 via WebCrypto), object-level decryption of every string and stream (object streams and cross-reference streams handled), then pdf-lib (vendor/pdf-lib.min.js, MIT) rewrites a clean unencrypted file with text, fonts and images intact — pages are not rasterised. Tested against RC4-40, RC4-128, AES-128, AES-256 (R5 and R6) files with user and owner-only passwords.
