依書籤分割 PDF
將每個有書籤標記的章節轉換成獨立檔案。
運作方式
上傳您的 PDF 並下載結果——檔案會依每個頂層書籤分割成一份檔案，並以該書籤命名。
這個工具使用哪些書籤？
PDF 現有的頂層大綱（目錄）項目——每個項目所指的頁面都會成為一個新檔案的起始頁。
如果我的 PDF 使用的是具名目的地連結，而不是直接的頁面書籤怎麼辦？
這類書籤會盡力跳過處理——此工具只能解析常見的直接頁面參照式書籤，無法處理所有 PDF 目的地類型。
What happens to pages before the first bookmark?
They're included in the first split file, since there's no earlier bookmark to start a new section.
Are the split files named after the bookmarks?
Yes — each output file is named using its corresponding bookmark's title, made safe for use as a filename.
What if my PDF has no bookmarks at all?
You'll see a message that none were found — use Split PDF instead if you want to split by page count or file size rather than by bookmarks.
Does it handle nested bookmarks, like sub-chapters under a chapter?
No — only the top-level entries in the outline are used. If a chapter has sub-bookmarks nested underneath it, those sub-sections aren't split out on their own; they just stay bundled inside that chapter's file along with everything else in its page range.
My PDF doesn't have bookmarks — can I add some first?
