Add Comments in PDF

We can add comments to any PDF file except protected PDF files. Comments are notes or drawings which convey ideas or are used to provide PDF feedback. Commenting functionality is often used to provide feedback to the author of a document, to write comments to yourself when reading documents. You may use it to write a few notes into a certain section of a Document or to add a few marks to point out something important.
