How Add PDF Bookmarks Works

Navigating a 100-page thesis, technical manual, or financial report without a sidebar outline forces readers to scroll endlessly to find the right section. Our Add PDF Bookmarks tool scans your document to detect prominent section headings automatically and populates an editable list of page-to-title pairs. You can refine the detected titles or type your own page numbers and chapter names to embed a standard clickable PDF outline tree that works in every desktop and mobile PDF viewer.
