You're reviewing a document and you need to leave feedback. You could email a list of comments, but that's messy. Or you could annotate the PDF directly — add sticky notes, text boxes, and comments right on the page.
Types of annotations
- Sticky notes: Leave comments that appear as yellow notes on the page.
- Text boxes: Add additional text anywhere on the page.
- Highlights: Mark important text with a colored highlight.
- Drawings: Add freehand drawings or shapes.

Best practices for annotations
- Be specific: Place annotations near the relevant text or section.
- Use color coding: Different colors for different types of feedback.
- Keep it concise: Short, clear comments are more useful than long paragraphs.
- Review before sending: Check that your annotations are clear and complete.
