My Golden Winston Badge is Defective

There are lots of Golden Winston badges and most of them look great. Here are a few of them:

And then there is the one I got (which I will post in a comment below because it is only letting me put one picture in this post).........

The background on my badge is a white square instead of transparent like every single other golden Winston badge. Which looks really bad and annoys me every time I see my badge. Is it possible that someone could quickly open up the badge's PNG file (math-winston.png (600×600) (kastatic.org)) in GIMP or something, make the background transparent and save it? It would be greatly appreciated.
