Password Protect a PDF — Free & Private

Frequently asked questions
What kind of encryption is used?
The file is encrypted with standard PDF encryption, so the password is required to open it in any reader.
What happens if I forget the password?
It can't be recovered — we don't store passwords. Keep your original, unencrypted copy somewhere safe.
Can I remove the protection later?
Keep your original unencrypted copy safe — we don't offer a password-removal tool.
Does my password reach you?
No — encryption runs locally in your browser; neither the password nor the file is sent to any server.
