How to protect a PDF with a password

Published 2026-08-15 · Tutorial

You share a sensitive document and want to make sure it cannot be read, printed or copied by anyone. Here is the method.

Opening password and permissions

Adding an opening password prevents reading without the password. The permissions (printing, copying) block further actions without preventing the opening.

How to proceed

Drop your PDF, enter the password, tick the permissions, then download the protected document.

Stay safe

Choose a strong password and keep it secret: the protection is only useful if the password stays private.
