Scanning complete!
After years of collecting, purchasing, and downloading music, duplicate files pile up. Same track, different sources. Same song, different bitrates. Same file, copied to multiple folders.
Manual cleanup is impossible. File names don't match. Metadata is inconsistent. And you definitely don't want to accidentally delete the wrong version.
No complex setup. No learning curve. Just point, scan, and clean.
Point DupeDJ at any folder containing your music collection. External drives, NAS, local folders - we scan it all.
We extract metadata, generate audio fingerprints, and compare files using multiple signals for maximum accuracy.
Preview duplicates, see quality recommendations, and move lower-quality versions to a review folder. Nothing is ever deleted—you stay in control.
Whether you're a touring DJ with terabytes of tracks or a vinyl collector digitizing your library, DupeDJ has you covered.
Industry-leading Chromaprint technology identifies duplicates even with different filenames, bitrates, or formats.

Finally cleaned up my 15-year DJ collection. Found over 2,000 duplicates I didn't even know existed. DupeDJ paid for itself in storage costs alone.
The audio fingerprinting is incredible. It found duplicates that were different rips of the same track, even with completely different metadata.
I was skeptical about the automatic quality detection, but it nailed it every time. Kept all my lossless files and flagged the lower quality duplicates.
