Password Protect PDF for notaries
Updated July 2026
Arthize lets notaries and signing agents password-protect a PDF in a private workspace — free, with no watermark. Protecting a PDF encrypts it with a password, so only people with the password can open the file — the encryption travels with the document.
Why notaries password-protect a PDF
A notary merges a loan package into one file for the appointment, captures signatures and initials, then archives the executed document as PDF/A.
Built for affidavits. Whether it's affidavits, acknowledgements, loan packages, Arthize's password protect pdf keeps the work inside your private workspace. Notarised documents carry identity and financial data; private handling is non-negotiable.
What matters when you password-protect a PDF
Password protection encrypts the PDF so it can't be opened without the password.
The encryption travels with the file, unlike a folder lock that stays on your computer.
A separate permissions password can restrict printing or copying.
