AntiDupl.NET can find and display duplicate images in the main graphic formats: JPEG, GIF, TIFF, BMP and PNG. The comparison is based on the contents of the files, so the program can find not only almost identical, but similar images.

Comments and Reviews

   
Comment summary: AntiDupl is often praised for its speed, efficient batch processing, and free, open-source nature. Users find its duplicate search and selection tools powerful, especially with features like caching and keyboard shortcuts. However, it may struggle with detecting similar (not exact) duplicates and has mixed results in accuracy versus other tools like Visipics. Some users note confusion with the interface, .NET dependency, and limited Linux support.

So far this is the best image duplicate search software in which you can compare the quality of images as well before deleting them. It automatically selects lower file sizes and lower dimensions and can even delete newer files with newer date if the file is exactly the same. I've tried a lot of such programs over the years and this one is the best one. It also caches images and is very fast (analyzing 100k images took 5 mins) so you don't have to waste time on every new search if you change only one folder location.

ok... but it's the .NET cancer bloat!

Excellent algorithm, marks the differences between two pictures, has great keyboard shortcuts to decide what to do with each duplicate pair that it finds. The only downside is I can't make it run on Linux.

The numpad system makes processing a long list of duplicates insanely faster than in any other program I've tried.

Update- I used xpadder to map the hotkeys to a gamepad and it's even better. Right bumper keep right image, left bumper keep left image, right trigger keep both, left trigger keep neither, one of the face buttons mark as false positive, bind another face button to undo... even better experience than before!

Out of about 50 duplicate images it found 1.

Review from a new or low-activity account — shown here, but not counted in the app rating.

[WebSite] link opens the developers NEWS (Home) page.

  • the News/Home page does NOT identify Languages (v1.2.3.10 is an updated CHINESE version) Clicking on the [ AntiDupl.NET-2.3.10.] link opens the downloads-table page, with all legacy editions. Including the English Edn. at number 2 on the table

The latest EN edition is v2.3.9 (01-09-2018) ... mm-dd-yyyy date format ... and not v2.3.10 which is implied by the NEWS page.

Text based Description is the only source of HELP ... from GUI and News (home) page

So far, the best anti-duplicate software, I've come across.
