If a PDF has an outline, you already have its table of contents. Every bookmark becomes a file of its own, starting at that bookmark and running to the next one, named after the bookmark itself. Level 1 bookmarks give you chapters; a deeper outline gives you sections, and you choose which level to cut on. Nothing is uploaded, no account is needed, and no watermark is added, so splitting a 500-page manual is a single click once you have picked the level.
To split a PDF by bookmarks, add the file, choose which outline level to cut on, and every bookmark at that level becomes its own PDF named after the bookmark. Runs locally with no upload, no sign-up and no watermark.
A technical manual with a two-level outline can become either forty chapters or two hundred sections. Cut on level 1 to get files you would email someone, cut on level 2 to get files you would keep on a share. The tool lists sizes for the level you pick, so compare before splitting.
When different people need different parts of one report, section files remove the need to redact anything. Nobody receives the appendix they were not meant to see, and there is no copy of it in their copy of the file.
Three common causes: the file was printed to PDF from a word processor, it was produced by scanning (a scan has no structure at all), or the exporter flattened the outline. In the first and third cases, a table of contents plus typed ranges works. In the second, OCR first — that recovers both text and heading structure.
Ebook-to-PDF conversions usually keep a chapter outline, which makes this the cleanest way to get per-chapter files. Names come from the chapter titles, so you get 01-prologue.pdf rather than part-001.pdf.
Splitting by bookmark needs an outline, and many PDFs — especially exported from word processors and converted from images — do not have one. Two honest routes: use Split PDF and type the page ranges from the printed table of contents, or use Split PDF by Text with a phrase that starts each chapter, which works even when the outline was lost.
Level 1 for chapters, which is almost always what you want. Deeper levels for manuals and reports where sections are the useful unit. The list shows the page count of each section before you commit, so a level that produces forty fragments of two pages is obvious immediately.
Everything before the first bookmark at your chosen level is prepended to the first file, so a cover page and preface are not lost. Anything after the last bookmark goes with the final file, which is where an index normally sits.
Yes, the ones that fall inside them. A chapter that contains subsections keeps its subsection bookmarks, so navigation inside the extracted file still works.
Yes. Every name in the list can be edited, which is how you turn BookmarkTitleOne into 01-introduction. Names are sanitised for your operating system, and duplicates are numbered rather than overwriting each other.
If the conversion produced an outline, yes — chapter bookmarks are exactly what an ebook conversion creates. If it did not, use Split PDF by Text with the chapter heading as the split phrase.
One per bookmark at the level you chose, plus nothing else. The count is displayed before you split, so a 90-chapter manual announces itself as ninety files rather than surprising you in your downloads folder.
Yes. Free, no account, no watermark, and the document is read and rewritten locally so it works offline.
