Unlock PDF

Frequently Asked Questions
Do I need to know the password?
Yes. This tool removes password protection from a PDF you're already able to open — it doesn't recover, crack, or guess forgotten passwords. Enter the correct password and the tool produces an identical PDF with the password requirement removed.
Is my file or password uploaded anywhere?
No. Both the file and the password stay in your browser the entire time. The unlocking happens locally using a PDF engine (MuPDF, compiled to WebAssembly) that runs entirely on your device — nothing is sent to a server.
Will this change the content or quality of my PDF?
No. This is a structural operation — it removes the encryption dictionary and decrypts the existing content streams. Text, images, and formatting are preserved exactly as they were.
