Add, Edit & Delete PDF Bookmarks Online for Free
Need to add a table of contents or organize chapters inside a large PDF document? Our client-side PDF Bookmark Editor reads the internal outline structure of your PDF and renders it as an interactive, drag-and-drop tree list. You can add new bookmark links, rename items, nest children up to 3 levels deep, delete outdated references, and configure exact page targets.
Once your edits are finished, download the rebuilt document. The tool compiles the new outline structure and generates your PDF locally in memory. Your private file remains fully secured inside your browser. No files are ever sent to remote APIs or cloud storage nodes.
