为 PDF 添加书签
选择页面并为其命名，构建可点击的大纲目录。
使用方法
上传您的 PDF，点击页面缩略图为其添加书签并命名，重复此操作——然后下载结果。
如何添加书签？
点击任意页面缩略图，即可添加指向该页的书签，然后在下方列表中为它命名。您可以添加任意数量的书签。
这会替换 PDF 中已有的书签吗？
是的——此工具会写入全新的大纲，因此如果 PDF 原本已有书签，下载后会被您刚创建的书签替换。
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.
