How to Track Changes in PDF? Automatically and Manually

If you often work with PDFs, such as for a project for school or on your team at work, then it's important to understand how to track changes in a PDF.

Tracking changes in a PDF makes communication easier among members of a group because you know exactly who made what changes. Tracking changes in a PDF also makes it very clear to see what revisions have been made and what revisions still need to be made. Tracking PDF changes also helps to maintain different versions of a PDF, in case you need to revert back to a previous version.

In this article, we'll discuss how to track changes in a PDF, both automatically and manually, including some frequently asked questions about tracking changes in a PDF.
