About Add bookmarks
Add bookmarks reads the headings in a PDF and adds them as clickable bookmarks (an outline) that show in the sidebar of Acrobat, Chrome, Edge and other PDF readers. Larger headings become main bookmarks and smaller ones are nested under them. If no headings are found, one bookmark is added per page. Nothing is uploaded.
