How does the Extract PDF Bookmarks work?
Pull the bookmark list out of a PDF and save it as plain text or JSON. Useful when you're re-publishing the document somewhere else (a website, an EPUB, a help portal) and need the navigation structure as data. Choose `text` for the human-readable `pageNumber,title` format, or `json` to get a parsed array your scripts can consume. The extraction runs entirely in your browser.
🔒 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.
