How to do it
- 1
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.
- 2
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.
- 3
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.
