Why Annotate PDFs?
Annotation is the process of adding notes, highlights, comments, and markup to a PDF without changing the underlying content. It's how teams review documents collaboratively, how students study effectively, how lawyers mark up contracts, and how editors give feedback on drafts.
Annotating a PDF is faster and cleaner than printing and marking by hand, and the annotations stay with the file when you share it.
Types of PDF Annotations
- Highlight: Mark important text in yellow, green, blue, or pink.
- Sticky Note / Comment: Add a pop-up note at any point on the page with your comments.
- Underline / Strikethrough: Mark text for emphasis or deletion.
- Freehand Drawing: Draw arrows, circles, or custom shapes to point out specific areas.
- Text Box: Add a visible text comment directly on the page.
- Stamp: Apply pre-made stamps like "Approved", "Rejected", or "Review".
