About this tool
Add a PDF that has bookmarks, such as a book, report or manual with a table of contents, and the tool lists the top-level bookmarks with their page ranges. One click saves each chapter as its own PDF inside a ZIP file. Nothing is uploaded.
When to use it
Long documents are usually organised by chapter. Splitting by bookmark gives you one file per chapter without counting pages by hand, which is handy for sharing a single section or for studying one unit at a time.
How the parts are decided
Each top-level bookmark starts a part that runs up to the page before the next bookmark. Nested bookmarks are not split further. If the first bookmark is not on page one, the pages before it become a start part.
No bookmarks?
Many PDFs have no bookmarks, especially scans. Use the Split PDF tool to cut by page ranges, or the Remove Pages tool to drop what you do not need.
Privacy
The work is done in your browser and the file is not uploaded.
