Remove a PDF password without uploading the file

Remove a password you know — the password never leaves your device.

Processed on your device — nothing is uploaded. Works offline.

How to remove a PDF password without uploading the file

  1. 1Choose the protected PDF.
  2. 2Type the password you open it with. If the file opens without one but blocks printing or copying, leave the box empty.
  3. 3Click Unlock and download a copy with the protection removed.

Every step runs in this tab. The site has no upload endpoint, and the page's security policy forbids the browser from contacting any other server — see how that is enforced.

When you'd use it

Your own protected statements

Bank and payslip PDFs that arrive locked with a password you're tired of typing.

Files sent with a shared password

Remove the password once so the file can be filed with the rest.

Print and copy restrictions

Documents you own that refuse to print — these unlock with an empty password.

Good to know

  • This works for files you can legitimately open. It does not recover forgotten passwords.
  • Decryption is done by qpdf compiled to WebAssembly, running in the page; neither the file nor the password is transmitted.

Don't trust us — test us

“Your files never leave your device” is a claim every PDF site makes. Here it is checkable in under a minute, three different ways:

  1. Watch the network.Open your browser's developer tools, switch to the Network tab, then run the tool. The only requests you will see are the site's own files — none of them carries your document — and once the app is cached there are no requests at all.
  2. Pull the plug. Load this page, turn off your wifi or switch on airplane mode, then use the tool. It keeps working, because there is no server involved and nowhere to upload to.
  3. Read the headers. The response headers for this page include a Content-Security-Policy with connect-src 'self': the browser itself refuses to send anything to another host, whatever the code asks.

Frequently asked questions

Is it safe to type the password here?

Yes — that's the point of this tool. Both the file and the password are processed in your browser's memory only. Upload-based unlock tools receive your password on their servers; here there is no server to receive it. Verify with your network tab, or go offline first.

Can this crack a password I don't know?

No. This tool removes protection from files you can legitimately open — you need the password (or the file must be restriction-locked only, without an open password). It is not a password recovery tool.

Does it work offline?

Yes. After your first visit the whole app is cached by a service worker, so the page loads and every tool works with no connection at all. Load the page, switch on airplane mode, and carry on.

Is there a file size limit?

No hard limit — your device's memory is the ceiling. Files up to a few hundred MB work well on a typical laptop. Very large files may be slow or fail on low-memory devices; nothing is ever truncated silently.

Do I need to create an account?

No. No account, no email, no cookies. The free tools are simply free.

Which browsers work?

Current Chrome, Edge, Firefox and Safari, on desktop and on phones. Phones have less memory, so very large files are better handled on a laptop.
