What Is PDF Annotation?

PDF annotation adds markup elements — highlights, underlines, strikethroughs, sticky notes, and freehand drawings — to a PDF document. Unlike editing, annotation is additive: it layers new elements on top of the original content without modifying it.

Annotations are the standard way to review, comment on, and mark up documents in academic, legal, and business contexts.

How to Annotate a PDF

1. Upload your PDF document.
2. Select annotation tool: highlight, underline, strikethrough, or notes.
3. Click and drag to annotate text or add sticky notes.
4. Click 'Save' to apply annotations and download.

How It Compares

Adobe Reader offers annotation tools for free, but many users find the interface cluttered. Dedicated review tools like Hypothesis focus on web annotation rather than PDFs.

This tool provides a clean, focused interface for common annotation tasks. Annotations are saved directly into the PDF and are visible in any standard PDF reader.

Tips

• Use different highlight colors to categorize different types of content
• Add detailed notes to important sections with sticky notes
• Export annotation summary for quick reference
