If you spend any time with a camera, you have lots of pictures on your PC - most likely hundreds of them, taking up gigabytes of space.
And no matter how good you think you are at managing your photos, you probably have plenty of duplicates, and they consume a substantial amount of your storage.
Trying to weed through everything and find duplicates is a wearying, thankless task.
VisiPics does all of that for you, for free.
It doesn't rely on looking for duplicate file names, either; it actually compares the photos themselves. Before you run the program, tell it whether you want the comparison to be Strict, Basic, or Loose, which determines how the program evaluates your photos.
It then shows the duplicates it uncovers, side by side. Mouse over any photo and its apparent duplicate, and you'll see them in a preview pane, where you can make sure that they're actually the same.
VisiPics can delete duplicate photos as well; just click on any duplicate you want to eliminate. Alternatively, you can have the utility move the duplicates to a folder.
I tested VisiPics on seven folders containing 359 photos, and it took a little more than 3 minutes to do its work.
I used the Loose setting, and the program listed 68 photos that it said were duplicates. About a quarter of those, however, were not actual duplicates, but the same scene taken from a slightly different angle.
When you use this utility, be sure to confirm that the images it unearths are in fact duplicates.
