Decent, not great

I tested this program on my wallpaper collection (2000+ images of varying resolutions).


  • Caches images, very fast after first initial scan.
  • You can mark matches as mistakes so they're never shown again.
  • Image previews are shown proportional, so larger images appear larger and vice versa.
  • Easy to use interface.


  • Only finds near-exact matches.
  • Missed many matches due to crops or differing resolutions which other programs found.
  • Turning up the threshold even a couple percent will result in hundreds of false duplicates.
  • I found the toolbar buttons for deleting images confusing, and had to be careful of what I clicked.

A good freeware for finding duplicate images and I do recommend it, but I find that Visipics is better at finding similar images.
