Bookmark Cleaner Open cleaner

Safety by design

Cleanup without risking your bookmark library

Bookmark cleanup is useful only when the user remains in control. The app produces a new file; it does not connect to Chrome's live bookmark database and cannot silently delete anything from the browser.

Manual decisions

No automatic deletion

Every duplicate starts undecided. The user explicitly chooses Keep, Remove, or Ignore, and can revisit groups before export. The original browser library is outside the app's reach.

Explainable results

Possible is not broken or disposable

Exact and normalized matches describe why URLs are grouped. Similar paths are labeled Possible and require extra care. A non-identical URL is never presented as a confirmed safe removal.

Required checkpoint

Backup before export

The cleaned export action remains locked until the original HTML has been downloaded as a dated backup. That backup preserves the original bytes, folders, titles, and URLs.

Output validation

Separate, verified Chrome file

Bookmark Cleaner creates cleaned-bookmarks.html rather than modifying the import. Before download, the output is parsed again and checked for structural validity and expected bookmark content.

A safe operating checklist

  1. 1. Keep the original Chrome export.
  2. 2. Review Possible groups manually.
  3. 3. Download the required backup.
  4. 4. Import the cleaned file and verify it in Chrome.
