FAQ
Is this tool free?
Yes — it is completely free to use, with no account or sign-up required.
What is this tool?
The PDF password tool lets you protect a PDF with a password (Lock) or remove the password from a protected PDF (Unlock). Lock encrypts the PDF with the password you enter; Unlock opens it with the correct password and re-saves it without encryption. Everything runs in your browser — the file and password are never sent to a server. If you forget the password, the PDF cannot be unlocked, so keep it safe.
Are my uploaded files sent to a server?
No. Everything runs only on your own computer, inside your browser, and your files are never sent to a server or anywhere else. So you can use it with complete peace of mind, without worrying about your file contents leaking.
