Markup, in the context of digital documents, refers to the act of annotating or adding notes. A PDF short for Portable Document Format is a commonly used file type that preserves formatting and layout across different devices. When you mark up a PDF, you’re essentially adding your own annotations to help you understand or share the document.
For instance, you could highlight important sections, add sticky notes to record your thoughts, or draw shapes to emphasize certain areas. These markups can make it easier to collaborate with colleagues, retain information, and quickly locate specific sections when you revisit the document.
