PDF Unlock removes password protection from a PDF when you already know the password, then saves a copy you can open freely. It does not bypass or crack passwords, you must provide the correct one. Everything runs in your browser, so your file and password are never sent to any server.
A password-protected PDF is easy to open when you know the password, but the prompt gets tiring when you open the same file every day, and it can stop the document from previewing or printing smoothly. PDF Unlock takes a PDF you can already open, decrypts it with the password you supply, and saves a clean copy with no password attached — so from then on it opens instantly like any normal PDF, with no prompt to type each time.
To be clear, this is not a password cracker. It cannot recover, guess or bypass a password you do not have — you must enter the correct one, exactly as it was set, for the file to decrypt. Everything happens inside your browser using open-source PDF libraries, so your document and the password you type are never uploaded or stored anywhere. It works on Windows, macOS, Linux, Android and iOS in any modern browser, so you can remove a known PDF password on your laptop or your phone without installing anything.
