About PDF Split by Bookmark
Got a long PDF with chapters or sections marked by bookmarks, and you want each one as its own file? Splitting by hand means hunting through dozens of pages. This tool reads the bookmark structure and cuts the document at each bookmark automatically, giving you neatly separated files.
Upload the PDF and the tool divides it wherever a top-level bookmark appears, producing one file per section bundled in a ZIP. It runs in your browser, so your document stays on your device. It's free, needs no signup, and adds no watermark. It's a fast way to turn a single bookmarked book or manual into individual chapter files.
