How to Protect Your PDF Files in a PDF Reader

Security is one of the main reasons why so many people, especially organizations, prefer to keep their important files in PDF format by using PDF reader.

For example, let us consider Microsoft Word. It does allow you to prepare documentation but doesn’t promise any kind of security. PDF readers on the other hand, let you encrypt entire PDF files and the content in them.

PDF readers let you protect files by applying passwords, give particular rights to specific individuals. In particular, PDF readers restrict from editing anything without permission.

Here’s how you can apply these security measures in your PDF file with the help of a PDF reader. This guide is written with Adobe Reader in mind, and may not be applicable in case you use a different tool, like Chromebook PDF reader.

Applying Password On A PDF File

In order to protect any PDF file, open the file and click on the file menu. The file menu will display a bunch of options, select properties. It will ask you to sign in, in case you aren’t logged in from your Adobe ID.

Some PDF readers might have a protect option that lets you encrypt a PDF or any other type of file.

Restricting Editing In A PDF File

PDF readers are reliable because they provide you the exact type of security that you need. If your need is to let people view the PDF file, read it but not edit it then it can be achieved using any latest PDF reader, such as Adobe Reader.
