Use case
How to Split PDF by Bookmarks
Create chapter-based output files from bookmark structure to break large PDFs into organized, shareable sections.
Implementation guidance
Large manuals, reports, and books often include bookmark outlines. Instead of manually selecting page ranges, bookmark-based splitting lets you export chapter files in one pass.
This method reduces manual errors and keeps document structure aligned with existing navigation. It is especially useful for education packs, project handoff documents, and legal bundles where each section must be shared separately.

FAQ
What if my PDF has no bookmarks?
Use Split PDF with manual ranges, or add structure in the source document before splitting.
Can nested bookmarks be split too?
Top-level splitting is most stable. Deep nested splitting depends on source bookmark structure.
Will chapter names be preserved in exported files?
Section outputs typically use bookmark-derived naming for easier organization.
Is bookmark split better than page ranges?
For structured documents, yes. It is faster and less error-prone.
