Split PDF By Bookmarks

Split your PDF by page ranges or at specific intervals. Perfect for separating chapters or sections.

Part of our Split PDF Files Online suite

About This Tool

Splitting PDFs by structure is a powerful way to organize complex documents. While fully automatic bookmark-based splitting requires advanced processing, you can use the page numbers from your PDF's bookmarks to split at logical section breaks. Open your PDF, note the page numbers where chapters or sections begin, then use those numbers to create your splits. This approach gives you documents that align with the original structure, making navigation and organization intuitive. Each split section becomes its own PDF, ready for individual use or distribution.
