How many of your bookmarks are already dead?

Upload your browser's bookmark export and find out. Free, no account, and your bookmarks are never stored — the file is read in memory and thrown away once the report is built.

Drop your bookmarks .html file here

Where do I get that file?

Chrome / Edge / Brave: Bookmarks → Bookmark manager → ⋮ → Export bookmarks
Firefox: Bookmarks → Manage bookmarks → Import and Backup → Export Bookmarks to HTML
Safari: File → Export → Bookmarks

Every browser produces the same format, so any of them works here.
