    1. Add a PDF that has bookmarks for its chapters.
    2. Choose the bookmark level to split at.
    3. Run the tool and download one PDF per chapter, named after its bookmark.

    Frequently asked questions

    What if my PDF has no bookmarks?

    There is nothing to split at, so the tool cannot work. Add an outline with the bookmarks editor first, or split by page ranges or every N pages instead.

    Which bookmark level should I split at?

    Top-level bookmarks usually mean chapters, and lower levels mean sections. Start with the first level for a book, and pick a deeper level only if you want smaller pieces.

    Why are my chapter files named strangely?

    File names come from the bookmark titles, so odd symbols or very long titles can look messy. Edit the bookmarks in the original first if you want tidier names.

    Is Split PDF by bookmarks free?

    Yes. Split PDF by bookmarks on Toolipedia is free to use, with no sign-up and no watermark.

    Does it work on my phone?
