Duplicate Clean

Private duplicate detection for music libraries on your Mac. Duplicate Clean compares file names, inferred artist and title, duration, size, format, and folder location to group likely matches. Drag in a folder, review each suggested keeper and copy, listen before acting, reveal the exact file in Finder, then move unwanted copies to the macOS Trash or to a separate folder. Scanning and playback stay on your Mac, with no account, advertising, or developer-operated tracking.

Like any DJ, I built a large music library over the years. Along with the tracks I wanted to keep came extra copies, slightly different file names, and folders that became increasingly difficult to manage.

I wanted a simple tool that could scan a music folder, bring likely duplicates together, and let me listen and compare before removing anything.

That practical need became Duplicate Clean: a focused way to review a large library, keep the version that matters, and clear the rest with confidence.
