Split PDF by Bookmark — Free Chapter Extractor

Overview

Long PDFs with bookmarked chapters are common — legal documents, technical manuals, annual reports. Instead of manually noting page numbers and splitting by range, you can use bookmarks as natural split points. PDF Mavericks reads your PDF's bookmark structure and splits it into separate files at each top-level chapter.

How to Use This Tool

Upload your PDF on the Split page. If the document has a bookmark outline, the tool displays the bookmark tree. Select the split-by-bookmark option. Each top-level bookmark becomes a separate PDF file. Download them individually or as a ZIP archive.

Frequently Asked Questions

What are PDF bookmarks?

Bookmarks are a navigation outline embedded in the PDF — like a table of contents that's clickable in any PDF viewer. They mark chapters, sections, or headings.

What if my PDF has no bookmarks?

Use the page-range split instead. Enter the start and end pages for each section you want to extract. You can extract multiple ranges in one operation.

Do the output files keep the original bookmarks?

Yes. Each split file retains any sub-bookmarks that were nested under its chapter in the original document.
