Split a PDF into Separate Files by Chapter
PDF Splitter works by page range rather than automatically detecting chapter breaks, so splitting "by chapter" means telling it the page range for each one yourself — check the book's table of contents for the starting page of each chapter, then add a range for each (for example, 1-22, 23-41, 42-60) covering the whole document.
Add as many ranges as you have chapters, and the tool produces one separate PDF file per range, all generated locally in your browser without uploading the source document. This is genuinely useful when you only need to read or reference one or two chapters and don't want to carry the entire book's file size around, or when you're distributing different chapters to different people.
If you'd rather cherry-pick specific non-contiguous pages instead of clean chapter ranges — say, just the pages you've been assigned to read, scattered across the book — Extract Pages is the better fit than splitting by range, since it lets you select any combination of pages rather than sequential ranges.
How to handle this workflow
Launch the PDF Splitter and load your document. No account creation or software installation is required.
Select your preferred settings. Core processing runs on your device, keeping your documents confidential and private.
Inspect the output to confirm page quality and formatting, then save your updated PDF directly to your device.
Does PDF Splitter detect chapters automatically?
No — it splits by page range, so you specify the starting page of each chapter yourself (usually from the table of contents) and add one range per chapter.
