How to Read and Add Comments to a PDF Document

Introduction

Comments act like revision tools for people reviewing and exchanging PDF documents.

Conventionally, comments added to a document represent inquiries, ideas, or concerns about a particular section or keyword within this document.

In general, you can add comments to any PDF document, unless security constraints have been applied to the document that prohibit commenting.

Objective

When we need to communicate with our colleagues about the content in a PDF document, it’s more straightforward to insert your comments in the PDF itself, rather than formalizing and dispatching these comments in an email or through any other communication channels.

This lesson will lay out the steps required to read and put comments on a specific keyword in a PDF document, while using a command-line utility developed in the Python programming language.
