Protect PDF

Lock a PDF with a password (AES-256) and choose whether printing and copying are allowed.

  1. Choose a PDF
  2. Set a password and permissions
  3. Encrypt and download

Keep the password safe — there is no way to recover it.

Required to open the file after protecting — don't lose it, there's no recovery.

Frequently asked questions

What encryption does this use?
AES-256, a strong industry-standard encryption algorithm, so the password genuinely protects the file rather than just hiding it behind a viewer prompt.
What permissions can I restrict?
You can choose whether printing and copying content out of the PDF are allowed, on top of requiring a password to open the file at all.
What happens if I forget the password?
There is no way to recover it — the encryption is real, so keep the password somewhere safe before you lock the file.
Is my PDF or password uploaded or stored?
Your file is processed to produce the protected PDF and is not kept afterward, and your password is not stored — there is no account and no storage.
Do I need to install anything or sign up?
No. It runs entirely in your browser and our server — no software install, no account, no email required.
