What is a PDF markup tool?
A PDF markup tool lets reviewers add visual markup and notes directly on the document—highlights, shapes, arrows, and freehand drawing—each tied to a specific place on the page. It replaces vague email threads with precise, actionable feedback.
PDF markup is how agencies collect legal, brand, and client notes on scripts, storyboards, and one-pagers. This free tool is ideal when you want a quick pass in the browser. When rounds stack up, switch to proof PDF on the platform and use compare PDF files to show what changed between versions. For a guided walkthrough, see how to mark up a PDF.
