Remove Duplicate Bookmarks from an HTML Export
Review duplicate bookmarks by folder, URL or tag. Keep selected groups, preserve supported dates and tags, and download a cleaned HTML backup locally.
Clean a bookmark backup
Export bookmarks as HTML in your browser, then choose that backup here. Processing stays in this tab.
UTF-8 HTML · up to 2 MiB, 10,000 links, and 128 nesting levels
Supported: folder order, titles, URLs, link tags, valid date fields, and toolbar-folder flags. Icons, descriptions, and other browser-specific fields are not exported.
Getting started
Keep your original HTML backup, then load it here. Choose global or per-folder matching, search duplicate groups by title, URL, folder or tag, review every path and optionally keep a whole group before downloading.
Before you use the result
Only the copy is edited. Supported dates, tags and toolbar-folder flags are retained, but icons and descriptions are omitted. Target browsers may ignore metadata. No dead-link or sync checks. Limit: 2 MiB, 10,000 links, 128 levels and 20,000 nodes.
Try an example
If the same URL appears three times after a Chrome/Safari sync, the preview marks two removable copies and keeps the first one.
How it works
Netscape bookmark HTML is parsed in this browser. Matching normalizes URL scheme, host and default port, while preserving different paths, queries and fragments.
