What Is PDF Annotation?

PDF annotation is the process of adding visual notes or markings to a PDF without necessarily changing the original document's underlying content.

Annotations can include highlights, comments, text boxes, drawings, shapes, arrows, and other markup elements that help explain, review, or emphasize information in a document.

What Can You Add to a PDF?

Depending on the available annotation features, you can add different types of markup to supported PDF documents:

• Text: Add additional text or comments to a page.
• Highlights: Emphasize important sections of text.
• Drawings: Draw freehand marks directly on a page.
• Shapes: Add available shapes to highlight areas.
• Arrows: Point to important information.
• Notes: Add comments or reminders where supported.

Annotate PDFs for Business

Businesses can use annotations when reviewing proposals, reports, contracts, presentations, plans, and other documents. Comments and visual markings can help teams identify important information during document review.

PDF Annotation vs PDF Editing

PDF annotation generally adds markup or comments on top of a document, whereas PDF editing can modify the original text, images, layout, or other content. An annotation does not necessarily change the original text itself.

If you need to permanently modify existing PDF text or images, use a dedicated PDF editing tool instead.

• Add comments to documents.
• Review contracts and proposals.
• Mark assignments and reports.
• Annotate research papers.
• Circle important information.
