為 PDF 新增書籤
選擇頁面並命名，建立可點擊的大綱目錄。
運作方式
上傳您的 PDF，點擊頁面縮圖為其新增書籤並命名，重複此步驟，然後下載結果。
如何新增書籤？
點擊任何頁面縮圖即可新增指向該頁的書籤，然後在下方清單中輸入名稱。可以新增任意數量。
這會取代 PDF 原有的書籤嗎？
會——此工具會寫入全新的大綱，所以如果 PDF 原本就有書籤，下載後會被您剛建立的書籤取代。
Can I create nested bookmarks (sub-chapters)?
This tool creates a flat, top-level outline — each bookmark points straight at a page. Nested sub-bookmarks aren't currently supported.
Can I reorder bookmarks after adding them?
Yes — remove and re-add them in the order you want, using the list controls shown once you've added more than one.
Will my bookmarks show up in any PDF reader?
Yes — bookmarks are written as a standard PDF outline, so they'll appear in the sidebar/navigation panel of Adobe Reader, browser PDF viewers, and most other readers.
Can I see or keep the bookmarks a PDF already has, and just add a few more?

Can I fake a hierarchy, like sub-bookmarks under a chapter, since nesting isn't supported?
Not structurally, but a naming trick works well in the outline panel: use consistent prefixes, like "2. Chapter Two" followed right after by "2.1 Setup" and "2.2 Usage". They all sit at the same flat level, but the numbering makes the grouping obvious to anyone browsing the sidebar.
Does it pull bookmarks automatically from my PDF's headings or table of contents?
No — every bookmark is added manually: click a page thumbnail, type a title, repeat. There's no heading detection, which is actually more reliable for scanned PDFs or files where headings aren't tagged properly — you decide exactly what gets bookmarked and what it's called.
