My PDF has no bookmarks — what can I do?

Use Split PDF to split by page ranges or every few pages instead.

How do I get the files?

They download together as a ZIP, one PDF per part, numbered in order.

Is my PDF kept private?

Yes. Your file travels over an encrypted connection and stays private to you — nobody else can open it. Projects you save are kept in your account until you delete them, and download links we email you expire after 7 days.

Split a PDF by its bookmarks

Long PDFs usually have bookmarks — the table of contents in the side panel of your PDF reader. Drop the PDF and they are read for you: each chapter becomes its own file, from its first page to the page before the next chapter, named after the chapter. Pick sections or sub-sections instead for smaller parts. Pages before the first bookmark (cover, contents) become a file of their own. Everything is downloaded together as a ZIP.

Automatic

Chapters found from the PDF's own bookmarks.

Named files

Each file is named after its chapter.

Any level

Chapters, sections or sub-sections.
