How does the Annotation Summary Report work?

Generate a one-page PDF report summarising the annotations found in a source PDF. The report shows total page count, total annotations, breakdown by subtype (Highlight / Text / FreeText / Square / etc.), per-page counts, and a tally of distinct authors. Useful as a cover sheet when forwarding a marked-up PDF to stakeholders, a quick "review temperature check" before deciding which pages need attention, or a snapshot for compliance archives showing what was annotated and by whom.

Frequently asked

The report still generates with all-zero counts. Marks drawn by our annotation tools are page content, not /Annot objects, so they will not appear here — see the Add Comment / Highlight tool descriptions for context.
