it's a program called FileOptimizer. it's free and open source and it basically allows you to put a file through a bunch of different file optimizers instead of just one. it works on a ton of different file formats, however it tends to break some so i'd recommend to use common sense if it's not just an image file you're optimizing https://nikkhokkho.sourceforge.io/static.php?page=FileOptimizer
