Unlock PDF
Remove a password you already know so the PDF opens without prompting.
Unlock PDF online, free and private
Password-protected PDFs are handy for sending sensitive material, but they become a nuisance once the file is somewhere safe. Every time you open a locked statement, contract, or scanned form you have to key in the password again — and printing, searching, or merging that file means fighting the prompt each time. Unlock PDF strips out the ‘open’ password you already know so the document opens freely from then on.
The whole thing happens inside your browser. Your PDF is decrypted locally with a WebAssembly build of qpdf, then handed straight back to you as a download. The file and its password are never uploaded to a server, which matters a great deal for the kind of documents people bother to encrypt in the first place.
How to unlock pdf in your browser
- 1
Add the locked PDF
Click ‘Select PDF file’ or drop your encrypted document onto the page. Because everything runs locally, even the file you are about to unlock stays on your device.
- 2
Enter the current password
Type the password you normally use to open the PDF. This is required — the tool decrypts the file with the password you provide, it does not guess or crack unknown passwords.
- 3
Unlock the document
Press ‘Unlock PDF’. qpdf removes the encryption inside your browser and produces a fresh copy of the file with no password on it.
- 4
Download the open PDF
Save the unlocked file. It opens without any prompt and behaves like a normal PDF — ready to read, print, search, or feed into other tools.
Why use PDFToolz for this
Password never leaves your device
Both the PDF and the password you type are processed entirely in local memory. Nothing is transmitted, logged, or cached on a server, so there is no remote copy of your confidential document or its credentials to worry about.
A faithful, lossless copy
Decryption only removes the security layer — it does not re-render or re-compress your pages. Text stays selectable, fonts and images keep their original quality, and the page layout is identical to the locked original.
Free with no limits
There is no account, watermark, or file cap. Unlock as many PDFs as you need, as often as you need, at no cost, because all the work is done by your own browser.
Fast and works offline
qpdf runs as WebAssembly right on the page, so unlocking takes seconds and needs no round trip to a server. Once the page has loaded you can even disconnect from the internet and it still works.
