AntiDupl

Typically, modern computer users have large collections of images in various formats. With more of these collections, it is more likely to have a large number of duplicates. The natural desire of the user is to get rid of them. However, if the collection is large enough, performing this manually is a very tedious and unproductive task. AntiDupl.NET is a program to help you automate this process. It can find and display duplicate images in the most common graphic formats: JPEG, GIF, TIFF, BMP, PNG, EMF, WMF, WEBP, EXIF, ICON, JP2, PSD, DDS, HEIF, HEIC, TGA, AVIF and JXL. The comparison is based on the contents of the files, so the program can find not only almost identical, but also similar images. In addition, the program can find images with some types of defects.

AntiDupl.NET is free and open-source software. It is simple to use, has high speed and accuracy of work, and supports Russian and English interfaces.
