Types of PDF Password Protection

Owner Password

Owner passwords restrict actions such as printing, copying text, editing content or filling forms. These restrictions can be removed instantly without a password.

User Password

User passwords prevent opening the PDF file itself. To unlock such files, the correct password must be provided once.
