How to Extract Comments from a PDF

  • Upload the PDF containing comments or annotations.
  • Click Extract Comments to scan all pages and list every annotation.
  • View the results in the table, or download them as a text or JSON file.

Example

A 20-page reviewed document yields a table showing 15 annotations: page numbers, authors (e.g. "Alice"), types (Highlight, Note, FreeText), and the content of each comment — ready to export as JSON for downstream processing.

Common Use Cases

  • Collecting all reviewer feedback from a shared PDF into a single list.
  • Exporting annotation data for import into a project management tool.
  • Proofreading a document by reviewing every highlight and comment in order.

FAQ

  • What types of annotations are extracted? All types that have content or a popup — highlights, text notes, stamps, free-text annotations, and more.
  • Will it find empty sticky notes? Only annotations with visible content, an author, or a popup are listed.
  • Is my file uploaded anywhere? No — extraction runs entirely in your browser.
