Questions about Add Password

How do I put a password on a PDF on Mac?

Drop the PDF into Add Password, enter the password twice and click Add Password. A protected copy is saved; the original is not changed.

What if I forget the password?

There is no way to recover it. Keep the password somewhere safe, such as the Passwords app.

Do the printing and copying limits always work?

Apps that respect PDF permissions, like Preview, enforce them after the PDF is opened. Some apps may ignore them, so the open password is the real protection.
