  1. Hello,

    PixCompare helps me a lot when cleaning up the photo-collections of my wife and mine. Fortuntely these was all .jpeg or .jpg.
    My Voila-collection of screenshots unfortunately is in .png. For various reasons I don’t like the idea to convert all screenshots to .jpg but there are a lot of duplicates because of optimization of workflow.

    To clean up the mess I’d greatly appreciate a PixCompare able to use .png.

    Best regards and continue your well appreciated work

  2. Just wanted to compliment you on PixCompare. I stumbled on it whilst looking for a duplicate detector.

    It has worked flawlessly and detected all the duplicate images I expected to find.

    You are a credit to application programming. Your app is functional, streamlined and unbloated, and it does what is says on the tin!

    Well done and thank you for a brilliant and extremely useful application!
