Common questions
Frequently Asked Questions
What if my PDF has no bookmarks?
The tool requires bookmarks to determine split points. Add bookmarks first using the 'Add Bookmarks' tool, then split.
Can I split by top-level bookmarks only?
Yes. Only top-level bookmark headings are used as split points. Sub-bookmarks stay within their parent chapter.
How are output files named?
Each output file is named after its corresponding bookmark title, making it easy to identify chapter or section files.
Can I split a textbook into chapters?
Yes. If the textbook has bookmarks for each chapter, this tool creates one PDF per chapter automatically.
