How does the Export Annotations to JSON work?

Walk every page's Annots dictionary in a PDF and export every annotation object to JSON. Each entry includes page number, subtype (Text / Highlight / FreeText / Link / Square / Circle / etc.), rect [x1,y1,x2,y2], author, and contents. Useful when you want to programmatically process annotations — feed them into a review tracker, transform them, or migrate between PDFs. Note: marks drawn by our other tools (Highlight Text, Add Comment, etc.) are page content, not real annotation objects — this tool only finds Adobe-style /Annot dictionary entries.

🔒 Security & Privacy

All processing happens on your device. Your files never leave your browser, never touch our servers, and are not stored anywhere. Close the tab and the file is gone.

📱 Use it on any device

Works in any modern browser — Mac, Windows, Linux, iPhone, Android, and tablets. No installation, no app to download. Just open the page and start.

⚡ Quick & easy

Drag, drop, click. Most files process in seconds, not minutes. No watermarks added to your output, no per-day limits, and the tool always shows the result before asking you to download.

🎁 Always free, no signup

Free to use, every time. No account creation, no email required, no “trial” that converts to a paid plan. We make money from ads so you don’t have to pay.

Frequently asked

Same data, JSON shape instead of comma-separated rows. JSON preserves nested structure and is easier to consume programmatically; CSV is friendlier for spreadsheets.
