Bookmark Cleaner & Organizer

Import a bookmarks file exported from your browser, spot duplicate links, remove the ones you don't need, and export a cleaned-up file to import back. Everything happens in your browser — nothing is uploaded.

Import your bookmarks

Click to select your exported bookmarks .html file

In Chrome: Bookmarks menu → Bookmark Manager → ⋮ menu → Export bookmarks. In Firefox: Bookmarks → Manage Bookmarks → Import and Backup → Export Bookmarks to HTML.

No bookmarks imported yet. Select your exported bookmarks file above.

Frequently asked questions

Will this delete bookmarks directly from my browser?
No — it only works on the exported file you import. To apply the cleaned-up result, you'll need to import the downloaded file back into your browser afterward (most browsers let you choose to replace or merge on import).

Does this check if the links still work?
No, this tool only organizes and de-duplicates what's already in your export — it doesn't visit any of the links, since checking hundreds of live URLs from a browser tab isn't reliable due to cross-site request restrictions.

Can I use this across different browsers, like exporting from Chrome and importing into Firefox?
Yes — the bookmarks HTML export format is a shared standard supported by Chrome, Firefox, Edge, and Safari, so a cleaned file exported here should import into any of them.
