Free Bulk PDF Unlocker

Take the password off lots of PDFs, or whole folders of them, so they open without asking. You need to know the password: this tool does not guess or crack passwords.

Quick human check, then the tool unlocks:

Drop locked PDFs or whole folders here Up to 100 MB per file.

Password Show passwords I own these files or have permission to remove their protection. This is needed to remove printing and copying restrictions from PDFs that open without a password.

How to unlock PDFs in bulk

Drop in your locked PDFs, or press Choose a folder.
Type the password. If the PDFs use different passwords, put each on its own line.
Press Unlock PDFs, then download each PDF or everything as one ZIP that keeps your folder layout.

🔒 Each PDF and its password are sent over an encrypted connection, used once to unlock the file, and deleted right after. Passwords are never saved or logged.

Good to know

The unlocked PDF is exactly the same as before, just without the password. Nothing is recompressed or changed.
Either password works: the one that opens the PDF, or the owner password that controls its restrictions.
Some PDFs open without a password but block printing or copying. Tick the permission box to remove those restrictions from your own files.
Forgotten the password? This tool can't help. It only removes passwords you already know.
