What is PDF Annotation?
PDF Annotation lets you mark up PDF documents directly in your browser — add text notes, highlight passages, draw freehand, and insert shapes. All annotation happens locally so your documents remain private.
How to use
- Upload a PDF document you want to annotate
- Use the toolbar to add highlights, text notes, freehand drawings, or shapes on any page
- Navigate between pages, then download the annotated PDF with all markups embedded
Result
Reviewing a 20-page contract — highlight key clauses in yellow, add margin notes with questions for your lawyer, circle a suspicious date, and download the annotated version to share.
