How to unlock a password-protected PDF
Remove a password from a PDF you already have the password for — safely, since the file and password never leave your browser.
The quick version
Upload the file to Unlock PDF, enter the password you already have for it, and download a new copy with no password required to open it. That's it — no account, no waiting, and nothing is sent to a server in the process.
What this tool is (and isn't)
This isn't a password-cracking or password-recovery tool. It removes a password from a PDF you can already open — the same way you'd remove a physical lock you have the key to. If you've genuinely lost the password with no record of it anywhere, there's no legitimate way to get it back for free; be wary of any site that claims otherwise, since "guaranteed PDF password recovery" services are frequently either scams or malware delivery.
Why avoid the sites that ask you to upload your PDF first
A large share of the "remove PDF password online" results are sites where you upload your file to their server, they process it there, and you download the result. That means both your document and the password you type in leave your device and pass through a system you have zero visibility into — for a bank statement, a legal document, or anything with personal or financial information, that's a real exposure. Unlock PDF works differently: it opens and decrypts the file locally in your browser using pdf.js, so nothing is ever transmitted anywhere.
The one tradeoff to know about
Because the library this tool relies on can't directly re-save an encrypted PDF's original content, it works by opening the PDF with your password, rendering every page as a high-resolution image, and rebuilding a fresh, password-free PDF from those images — the same technique Compress PDF and Grayscale PDF use. Any real, selectable text in the original becomes part of a picture in the output, so it can no longer be selected, searched, or copied. For the common case — you just need the password gone so the file opens normally for viewing, printing, or sharing — this doesn't matter. If you specifically need to keep selectable text, this isn't the right tool for that particular need.
