I was going to upload one of my first pixel art pieces which is 32x32. First, I uploaded a upscaled version, since it was not super clear that I should post original size. But then I saw dimensions written on top of preview and it made me decide I am supposed to do the original (and also then I read tiny hint "Can zoom in to see the pixels without blurring, scales up by default" which assured me it has to be original size). Then I posted the original, but it is all blurry in both previews :(
