Runs entirely in your browser. Nothing leaves your device.

How it works

  1. Export bookmarks from Chrome, Firefox, or Edge as a bookmarks HTML file.
  2. Drop the file here to get a local analysis of duplicates, empty folders, and tracking parameters.
  3. Choose the cleanup options you want; the original export remains untouched.
  4. Download a cleaned bookmarks.html file and import it only after reviewing the result.

Clean bookmark clutter without giving up your original file

Bookmark libraries get messy slowly. Browser sync merges old folders, repeated imports create duplicates, and links saved from newsletters or ads often carry tracking parameters that make the same page look different. A cleaner export gives you a portable way to tidy the library before re-importing.

This tool reads the standard bookmarks HTML format locally in your browser. It reports duplicate URL groups with folder locations, counts empty folders, and identifies links with tracking parameters such as utm_*, fbclid, gclid, mc_eid, and igshid. The download is a new file, not an edit to your original export.

The duplicate strategy matters. Keeping the first copy is conservative and preserves export order. Keeping the deepest-nested copy is useful when a flat import folder and a carefully organized folder both contain the same link; the deeper folder is often the one you meant to keep.

Frequently Asked Questions

Why do I have duplicate bookmarks?
Duplicates usually come from browser sync merges, repeated imports, or saving the same page into multiple folders over time. The cleaner groups likely duplicates by matching address so you can see where they live before downloading a cleaned copy.
Which copy is kept?
By default, the first copy in the export is kept. You can switch to keep the deepest-nested copy, which is often the more intentionally organized bookmark when a duplicate also exists in a flat import folder.
Is it safe, and can I undo?
Your original export is never modified. The tool downloads a new cleaned bookmarks.html file, and browsers usually import it into a new folder instead of replacing existing bookmarks. Keep the original export until you are happy with the result.
Does it check for dead links?
No. This cleaner removes duplicates, empty folders, and tracking parameters. Use the Dead Bookmark Checker if you want a separate reachability scan for dead domains and unreachable servers.

Bookmarks rot because saving is easier than organizing.
