PDF Annotations → JSON

Export annotations from a PDF (comments, highlights, notes, drawings, links…) to JSON format, locally in your browser.

Import a PDF

No data is sent to a server: everything is done in your browser.

Comment AuditList notes, highlights, and stamps before archiving or sending an annotated PDF.
Annotation MigrationExtract a JSON structure to reconstruct annotations in another tool (DMS, viewer, QA workflow).
Quality ControlCheck that a document contains the expected annotations (pages, positions, authors) in a CI/CD pipeline.
Security & ComplianceDetect hidden annotations containing sensitive data (internal comments, attachments, content).

A JSON export of annotations per page (type, rectangle, content, author, dates, flags, associated action).

Actionable information to filter, compare two versions of a PDF, and automate an audit report.

Some annotations may have a complex appearance: the JSON describes the structure, not always the exact appearance.
On encrypted or heavily damaged PDFs, extraction may be partial or impossible.
Annotation data may contain personal information (author, content): consider anonymizing before sharing.

Does the tool modify my PDF?

No. It reads the file and generates a JSON; your original PDF remains unchanged.

Are clickable links included?

Yes, most links are annotations (URI / GoTo) and appear in the export.

Why can't I see certain highlights?

Depending on the PDF, some elements may be "flattened" or drawn in the page content rather than as annotations.

For a complete audit, combine this export with 'PDF Links → JSON' and 'PDF Metadata → JSON' to capture both annotations, URLs, and document info.
