How to Remove a Password from a PDF

PDFToolShack’s Unlock PDF tool runs entirely in your browser using pdf-lib.js. Your file is decrypted locally using the password you provide, and the unlocked PDF downloads directly to your device — no server contact, no data stored, your password never leaves your browser.

When you load a PDF, the tool automatically detects what type of protection it has. If it has an open password, you’ll be prompted to enter it before unlocking. If it only has permissions restrictions (print/copy/edit locks) without an open password, it can often be unlocked directly without a password at all.

This tool only works if you already know the password. It does not crack, guess, or brute-force passwords — use it only on documents you own and have the right to unlock.

Frequently Asked Questions

Can this tool crack a PDF I don’t have the password for?
No. This tool cannot crack, guess, or brute-force passwords. It works by using the correct password you provide to decrypt the file. If you don’t know the password, this tool cannot help you.
Is my PDF or password sent to your server?
No. Everything runs entirely in your browser. Your file and your password never leave your device. Nothing is transmitted to any server at any point.
My PDF opens fine but I can’t print or copy from it. Can I unlock it?
Yes — this is a permissions-only restriction, which doesn’t require an open password. Load the PDF and try clicking Unlock without entering a password. Permissions-only PDFs can usually be unlocked directly.
What’s the difference between an open password and a permissions password?
An open password must be entered before the PDF can be opened at all. A permissions password doesn’t block opening but restricts what you can do — print, copy, edit, or annotate. Both types can be removed with this tool if you have the correct password.
Will unlocking affect the content or quality of the PDF?
No. Removing password protection only changes the encryption metadata. All page content, images, fonts, and formatting remain completely intact.
Is it legal to unlock a PDF?
Unlocking a PDF you own and have the password for is perfectly legal. Removing protection from PDFs you don’t own or don’t have authorization to modify may violate copyright law and/or the PDF creator’s terms. Only use this tool on documents you have the right to unlock.
