Before you start
- Once the file is in, every chapter is listed with its pages — check the list before you split.
- Need the sections too? Go one level deeper to split at the sub-headings as well.

Run this tool and the next one back to back — nothing to download in between.
How to do it
Add your file
Add a PDF that has bookmarks — a report, a book, a court bundle. The document already knows where its own chapters begin, which is what this uses.
Set it up the way you want
Choose how deep to split. Level zero uses only top-level bookmarks; going deeper splits at sub-sections too, which can produce a lot of files.
Download the result
Download the parts. Each file is named after its bookmark, numbered so the order survives in your folder.
Questions about Split by bookmarks
- It says there are no bookmarks.
- Then the document has none, and there is nothing to split on. Use Split PDF to cut at page numbers instead, or Extract pages to pull out a specific range.
- What happens to pages before the first bookmark?
- They become their own file rather than disappearing. A cover and a table of contents usually sit there, and silently dropping them would lose the first pages of your document.
- Why did it skip one of my bookmarks?
- Because its target could not be resolved to a page. Rather than guess, it skips — cutting at the wrong page would split a chapter down the middle, and you would only notice after sending the files on.
