About PDF Unlock
This tool removes the user-password (open password) from a PDF file when you supply the correct password. It uses PDF.js to read the encrypted document and pdf-lib to produce a new, unprotected copy. It does not crack or brute-force passwords — you must know the password to unlock the file.
Use case: You have a password-protected PDF that you own or have permission to unlock, and you want to save an unprotected copy for easier access.
