About Split PDF by Bookmarks

Long PDFs often already contain bookmarks for chapters, sections, invoices, or report parts. Splitting by bookmarks uses that internal outline as a ready-made table of contents, so you do not need to type page ranges manually.

The first version handles common bookmark destinations that point directly to pages. Some PDFs use complex named destinations, and those may need a desktop PDF editor. When usable bookmarks are detected, the tool previews each output range and exports a ZIP of separated PDFs.

Everything runs locally in the browser. For files without bookmarks, use Split PDF by range or Organize PDF for visual page selection.
