How to Password-Protect a PDF
Sending a PDF with sensitive information and want it locked behind a password? Serbabisa's Protect PDF tool encrypts the file on your device using a password only you choose, it's never sent anywhere, not even to Serbabisa.

Frequently asked
What if I forget the password?
There's no way to recover it. Serbabisa never sees or stores the password, it only exists on your device, so losing it means losing access to the encrypted file.
Does this let me restrict printing or copying while still letting people open it without a password?
No, Protect PDF sets a single password that's required to open the file at all, there's no separate permissions-only mode.
Is my file or password uploaded anywhere?
No. Encryption happens entirely on your device, so neither the PDF nor the password is ever sent to a server.
