PDF nach Kapitel oder Lesezeichen teilen — Buchabschnitte extrahieren

Häufige Fragen

Does this work on any PDF with bookmarks?

Yes. As long as the PDF has an outline (bookmark tree), the splitter enumerates it and uses each top-level or second-level entry as a chapter boundary. Most textbooks, manuals, and research PDFs include one.

What if my PDF has no bookmarks?

The splitter falls back to 'every N pages' mode where you choose the chapter length. For better results, add bookmarks first using a dedicated PDF editor, or split by detected page count.

Are figures and tables preserved correctly per chapter?

Yes. Each chapter PDF contains all pages from its start bookmark to the next bookmark — including figures, tables, footnotes, and references. Layout is identical to the original.

Can I split only selected chapters instead of all?

Yes. The outline view is a checklist. Untick the chapters you do not want, and only those you check are extracted into the ZIP output.

Does it work on DRM-protected PDFs?

No. DRM-encrypted PDFs (e.g., from Kindle, Apple Books, or publisher-locked textbooks) cannot be split — they require authorized removal first via the PDF Unlock tool, and many publishers prohibit this in their terms.

Will the output PDFs be searchable?

Yes if the original was searchable. Text-based PDFs preserve their text layer through the split. For scanned (image-only) PDFs, run each chapter through the PDF OCR tool after splitting.

How is this different from a regular split tool?

The regular split tool requires you to specify exact page ranges. The chapter splitter reads the bookmark structure and figures out the boundaries automatically — much faster on 20+ chapter books.
