Bookmark Manager & Duplicate Cleaner
Bring order to years of saved links. Import your browser bookmarks, tidy folders, review duplicates and preview URL cleanup before exporting a collection you can use again.
Try the example, or start your own project. Download a project to keep your work.
Imports add to this working collection. New project clears it; Undo restores the previous state.
URLs are compared using these settings. Removal is never automatic: preview the changes, then apply them. Fragments and query order can affect some websites.

Useful import details
CSV columns: title,url,folder,tags. Only url is required. HTML import supports the nested folder structure commonly exported by desktop browsers.
The cleaner preserves path case, HTTP versus HTTPS and trailing slashes. Known tracking keys include utm_ parameters, gclid, fbclid, dclid, msclkid, mc_cid and mc_eid. It does not resolve redirects or treat all similar-looking URLs as identical.
Browser HTML exports do not carry this tool’s tags. Save a project or CSV to retain them.
Your bookmarks stay under your control
Export an HTML bookmark file from your browser first. This tool edits a separate working copy; it cannot access or change your browser collection directly. Re-import the downloaded HTML when you are ready.
Up to 5,000 HTTP(S) bookmarks and 5 MiB per import. Unsupported schemes are skipped with a count. Tracking cleanup is optional and previewed. No links are fetched, so this tool does not certify that a page is working or safe. Folder paths use “ / ” as a separator; tags are retained in project/CSV exports, not the browser HTML format.
Processing runs in this browser. Projects are not automatically saved. Site advertising and optional analytics follow the website’s privacy and consent settings.
Using Bookmark Manager & Duplicate Cleaner
Import browser bookmarks, organize folders and tags, find duplicate destinations, preview tracking-parameter cleanup and export a clean browser bookmark file or CSV.
- Import a browser bookmark HTML file or CSV, or try the example collection.

- Review duplicate groups and optional tracking-parameter cleanup before applying changes.
- Export browser-compatible HTML, CSV or a project file.
Example
The demo includes repeated destinations and tracking parameters so you can compare exact and cleaned-URL duplicate detection.
Questions & answers
Can it modify my browser bookmarks directly?
No. Export bookmarks from your browser, import that file here, then import the cleaned HTML back into the browser. Your existing browser collection is not changed automatically.
Does it check whether links are broken?
No live requests are made. It checks URL syntax and duplicate destinations. It cannot confirm availability, redirects or page safety.
What does tracking cleanup remove?
Only the selected known tracking keys, such as utm parameters and click IDs. Review the before/after preview; some websites use query parameters for essential behavior.
What are the limits?
Up to 5,000 HTTP(S) bookmarks and a 5 MiB import file. Unsupported schemes are skipped with a count. Folders and bookmark titles are retained; browser-specific metadata and toolbar placement may differ on re-import.
Can I save and reopen my work?
Yes. Save project downloads a JSON file for this tool. Open project restores it. Projects are not automatically saved; download a copy before leaving.
Is my input uploaded?
Processing runs in your browser without a processing upload. Public pages may include advertising and optional analytics governed by the site privacy and consent settings.
