DupHunter

DupHunter is a tool that allows you to automatically filter the best images from a series of similar photographs, so that you can get rid of the worst ones and keep the best.

Using it is very simple: select the folder holding the photographs, and wait for the program to process them. Within a few seconds, it will display the different groups of images that it found, and the best option in each.

Once you've looked at your options, you can choose whether you want to erase the alternates, or simply save everything and leave the alternates for another time. It's all up to you - the application won't make any decisions for you.

DupHunter is a tool that you can use to save time and disk space by getting rid of duplicate or very similar photographs that have poorer quality than the few that really came out nicely.
