Duplicate cleanup

Scan a messy folder in the browser and see duplicate clusters before you touch a file.

Why this tool exists

  • Shows exact duplicate groups and image near-matches in one pass.
  • Highlights recoverable space so the payoff is obvious fast.
  • Hands off the destructive part to DupeZappa where undo and history exist.

Local scope

No upload. No hidden apply step.

Pick a folder and let the browser worker inspect the files you expose. The results stay local and the delete or move decision stays inside DupeZappa.

Folder scan

Run the scan and inspect the groups.

Your browser is using directory upload fallback. The scan is still local, but empty folders cannot be detected.
