Did you know that you could actually track changes and monitor your PDF? Coding is not required and these changes can be as simple as showing markups on the review tab similar in Word. The software you will need for this is Adobe Reader, free software that can read, open, and annotate your PDF file. This tool can also track the changes in a PDF just by enabling comment and markup but of course, the original author of the document should be able to provide the same authorization to the reader to add comments.

Just like Word documents, the changes that can be tracked down includes annotation features such as editing, strikethrough, comment, and highlighting words.

How to Track Markups

Additionally, it can only be done if you have the right tool to add encryption, which you can easily access right here at
