What is the Use of PDF Annotation Files?

Annotations help you to make connections and see concepts clearly, you'll read more actively and understand more of what you read.  Annotations are effective but use them sparingly. You should not underline the entire document but rather the most crucial parts.

Methods for Manually Annotating a PDF

To annotate PDF files, you must use these methods. Here, we will show you three manual methods of how to mark up a PDF. Let's see what they are!

Text boxes, callouts, freehand drawings, preset shapes, stamps, and more are all part of the annotation toolbar, located just below the main toolbar.
