Frequently Asked Questions


How do I split a PDF by its chapters?

Simply drag and drop your PDF into the tool. Select the desired "Outline Level" (usually Level 1 for main chapters) and click "Start." The tool will detect the bookmarks and generate separate PDFs for each section.


Is it safe to use this online PDF splitter for confidential files?

Yes. Unlike traditional online converters, our technology processes the PDF directly within your web browser. Your file is not transmitted to our servers, making it safer than almost any other online tool.


What if my PDF doesn't have an outline?

This tool relies on internal PDF bookmarks. If your document lacks a digital outline, the tool will not be able to identify split points automatically. You may need to add bookmarks using a PDF editor first.
