Part 1. What Is Redlining a PDF?

Redlining a PDF is when you mark changes or add comments to a PDF document. Long ago, people used to do this on paper. They would take a red pen and write notes or draw lines to show changes. That's where the name "redlining" comes from.

Over time, as computers and digital tools became more common, redlining moved from paper to screens. Now, we can do the same thing on a PDF file. This change makes it easier for people to work together, no matter where they are. They can share a PDF, mark it up, and everyone can see the changes right away.

Redlining is very helpful. It makes things clear and reduces mistakes. When a team is working on a project, redlining helps them communicate better. They can quickly see what needs to be done and avoid confusion. This way, everyone can work more smoothly and finish the job faster.
