I grew up hanging around early 2000's era pixel art communities, so I not only know file formats, but I had very strong opinions on image formats when I was 13. I wouldn't have done any better at the AP submission than those kids did. If it's the default image format my device puts out, and the input doesn't tell me it's rejected, I assume things have worked out.
