How does the Add PDF Bookmarks work?
Add a clickable bookmark sidebar to a PDF — the navigation pane on the left in Adobe Reader, Preview, or any modern PDF viewer. Each bookmark links to a page; users click and jump. This dramatically improves long documents (manuals, reports, books) where readers need to jump around. Provide the list as `pageNumber,title` lines — one bookmark per line. Existing bookmarks are replaced. The conversion 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.
