How to: Split PDF by Bookmarks
- Select a PDF that has bookmarks.
- Choose the bookmark level.
- Click Start and download the ZIP of chapters.
Well-structured PDFs – e-books, manuals, standards and annual reports – contain bookmarks (an outline) that mark where each chapter begins. Splitting by bookmarks turns one huge file into tidy chapter files automatically, without you having to look up page numbers.
Common uses
- Break an e-book or textbook into one file per chapter.
- Split a technical manual so each team receives only its section.
- Separate a combined board pack into individual agenda items.
Tips for best results
- Open the PDF's bookmark panel first to check the outline exists and is accurate.
- Choose top-level bookmarks for chapters, or deeper levels for sections.
- No bookmarks? Use Split PDF by Text with a heading like "Chapter".
