Hey @RoseKawaii352 I hope you like your logo! How to use: Screenshot the image and then crop it to what you like, and then I think that automatically makes it a JPEG. That will probably be sorta low-quality, but the scratch profile picture has a limit of 500x500 pixels if you're using it for scratch, which is pretty low anyway, and also the logo itself will almost never be seen big.
If anyone wants their own logo just ask in the comments!
