Add clickable bookmarks & table of contents
Last updated: 2026-10-08
PDF Bookmarks is a free tool for adding clickable bookmarks and a navigable table of contents to a PDF document. Bookmarks appear in the PDF reader's sidebar — in Chrome's built-in viewer, Firefox, Edge, and most PDF apps, letting readers jump directly to chapters, sections, or key pages instead of scrolling manually — particularly useful for long reports, ebooks, or legal documents. Processing happens entirely in the browser, so the source file is never uploaded to a server. Bookmarks are added without altering any existing page content, text, or formatting, and the operation works regardless of document length. There is no file-size limit and no login requirement. Unlike PDF editing suites that require a paid license to add a table of contents, this tool is free and runs instantly in any modern browser, desktop or mobile, producing a downloadable PDF with the new bookmark structure embedded in its outline.
