Why split PDF by bookmark?
Long documents like textbooks, manuals, and reports often have bookmarks marking each chapter or section. Splitting at bookmarks automatically creates individual files for each chapter without you having to figure out page numbers. This is especially useful for study materials, where students might want to focus on one chapter at a time.
