Password Protect PDF Files

Let’s admit it, we all deal with PDF files while working on our computers. Over the years, the PDF file format has served as one of the most secure ways to share documents over the web.

The good thing about PDF is that they are secure, and the format doesn’t let you modify its data easily. You need a third-party PDF editing tool or premium PDF software to edit a PDF file.

Even though PDF is a secure format, you can make it even more secure by encrypting it. When you encrypt PDFs, a password is required to view their contents. The document format can be viewed natively in macOS and Windows, but you need a password to unlock the content.
