Full product details

Two ways to scan. UltraFast compares file names and lengths in seconds. Fingerprint listens to the audio and finds the same recording even under another name, without taking a remix for the original.

Duplicates appear in color-coded groups: each one shows the suggested original and its copies, and you listen, compare and decide.

No account, no ads, and nobody tracking you. Everything runs on your Mac.

Requires macOS 26 on a Mac with Apple silicon.

The story behind the app

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.
