Split PDF by Bookmarks
Break a big PDF into chapters at bookmark points — each chapter a separate PDF, all in one ZIP. Split chapters easily.
The PDF must have bookmarks (outline) — otherwise it cannot be split.
Level 1 = only main chapters; Level 2 = headings inside chapters will also be split
| # | Chapter | Pages |
|---|
How to use
- Select a PDF with bookmarks.
- Choose a level — only main chapters or sub-sections too.
- Press Split by Bookmarks, then download the ZIP.
Note: The PDF must contain bookmarks. If the file has no bookmarks, the tool will tell you — in that case use the page-range split tool.
