We can protect PDF with a password easily using your MAC Preview app. It is important to use protected files while you send any personal file by email. We are always sending the PDF files by email that contain Social Security Number or other crucial information without any protection.

You don’t need any PDF editing application or third party plugin to add the password. You can use your MAC Preview app and convert any files to Protected PDF File with couple of mouse clicks.

You can add password to any existing PDF or webpage using your MAC. Please see Convert Any Webpage to a Clean PDF in MAC to know how to convert webpage to PDF. Please go through the steps here to add password while you convert webpages into PDF.
