حول هذه الأداة
Split PDF by Bookmark divides a document into separate PDFs based on its top-level bookmarks (the outline). Each bookmarked section becomes its own file, named in document order and bundled into a single ZIP for easy download.
Great for breaking a bookmarked book, manual, or report into per-chapter files without manually entering page ranges.
All processing happens locally in your browser — your document never leaves your device.

الأسئلة الشائعة
What if my PDF has no bookmarks?
This tool needs bookmarks (an outline) to know where to split. If your PDF has none, use the regular Split PDF tool to split by page ranges instead.
How are the output files named?
Each file is named after its bookmark title and prefixed with a number so the sections stay in document order inside the ZIP.
Does it use sub-bookmarks?
Splitting is based on top-level bookmarks. Each top-level entry (and everything under it, up to the next top-level entry) becomes one PDF.
