Split PDF by chapters

How to split a PDF by chapters

1. 1. Upload a PDF whose chapters are bookmarks in its outline (most ebooks, reports and manuals are).
2. 2. Choose the top outline level so each chapter bookmark becomes its own file.
3. 3. Split, and download one PDF per chapter, bundled as a ZIP.

Frequently asked questions

How does “split by chapters” work?

A PDF's chapters are its top-level bookmarks (the outline / table of contents). We cut the file at each of those bookmarks, so you get one PDF per chapter. Pick a deeper outline level to split into sub-sections instead.

My PDF has no chapter bookmarks — what then?

Splitting by chapters needs an outline. If yours has none, use Split by text to cut at a repeating chapter heading, or Split PDF to split by page ranges.

Is it free and private?

Yes — free, no signup, no watermark, and your file is deleted within one hour of processing.
