An AI duplicate photo finder for macOS and Windows that never uploads a single photograph.
An AI duplicate photo finder for macOS and Windows. It scans any folder — including external drives — and finds exact copies as well as resized, recompressed and edited ones, using a carefully tuned on-device pipeline.
No cloud, no uploads: your photos never leave your computer. The whole detection pipeline runs locally on both platforms, which is the point — a photo archive is one of the most private things a person owns.
The easy case, handled first: byte-identical files scattered across a decade of folders.
The same photograph saved smaller, or re-exported at a different quality, still recognised as the same picture.
Crops and adjustments matched back to the shot they came from, rather than counted as new photographs.
Point it at a folder on either platform — including one on an external drive — and let it work through the archive.
A carefully tuned detection pipeline that runs entirely on your own computer's hardware, on macOS and on Windows alike.
No cloud service, no account, no uploads. The photographs never leave the machine.
PhotoDedupe will be launched soon for macOS and Windows. Nothing on this page is a promise of a feature, a date or a price.
We invite a small circle of testers before every release. Write to us and say you're interested in PhotoDedupe.
