Bookmark Cleaner

Review duplicate bookmarks locally, back up first, and export safely. Nothing is deleted automatically.

Clean years of accumulated bookmarks without handing your bookmark library to a cloud service. Bookmark Cleaner helps you scan your current browser bookmarks or import a Netscape-format `bookmarks.html` file, understand duplicate groups, review every proposed change, create a backup, and export a Chrome- and Firefox-compatible cleaned file. Core safety and privacy principles: - Bookmark titles, URLs, and folder paths are processed on your device. - Nothing is deleted automatically. - You decide whether to Keep, Remove, or Ignore each result. - A backup is required before a cleaned file can be exported. - Folder structure, bookmark titles, and URLs are preserved. Free features: - Scan the current browser bookmark tree after you grant optional bookmark access. - Import and parse Chrome/Firefox `bookmarks.html` exports. - Find exact, normalized, and possible duplicate groups. - Review duplicate reasons and make manual decisions. - Generate a byte-for-byte backup of an imported file. - Export a cleaned, re-importable bookmark file. Optional Pro v1 features: - Advanced local bookmark diagnostics and configurable URL cleanup rules. - Review bookmarks by domain. - Safe cleanup suggestions that prepare decisions but never delete automatically. - Local backup vault and privacy-safe aggregate reports. - Link Health checks in the extension, started only by you and using optional website access. Authentication-required, blocked, redirected, or uncertain results remain Needs Review; an HTTP response is not treated as broken in every case. The same Pro key works on Bookmark Cleaner Web and supported browser extensions for up to three active browser installations. Payment is completed on the Bookmark Cleaner website, never inside the extension.
