Split PDF by bookmarks, one file per chapter
One file per chapter, taken straight from the document outline. No page counting.
How to split at the bookmarks
- 1
Open the file
It needs bookmarks — most reports and ebooks have them.
- 2
Pick the level
Split at top-level bookmarks, or go deeper for sub-sections.
- 3
Split
Each part is named after its bookmark.
Private by design
Your files are processed on your own device and never uploaded to a server.

No waiting for uploads or downloads. Results are ready in seconds.
Free, no signup
Use every tool without creating an account or adding a watermark.
Frequently asked questions
There are no bookmarks in my file.
Then split by pages or by a phrase instead. Scans almost never carry bookmarks.
What are the files called?
After the bookmark text, so the chapter names survive into your folder.
Where is my file processed?
On your own machine. The tool is code that runs inside your browser tab, so the document is never sent to us and never sits on a server waiting to be cleaned up.
