Frequently Asked Questions

Is it free?
Yes, no account needed.

Does my PDF or password get uploaded anywhere?
No, the whole process runs entirely in your browser — neither your file nor your password ever leaves your device.

Can you remove a PDF's password if I don't know it?
No — this tool only removes a password you already know. It doesn't try to crack an unknown one.

What encryption is used when I add a password?
256-bit AES encryption — the strongest level the PDF standard supports.

What happens if I forget the password I added?
We don't store it, and your file is processed in your browser — if you forget it, the PDF can't be opened. Keep your password somewhere safe.
