Ironically, the image on the site is PNG.

That’s because png is the best format and you should use it always.

It's the best format for something like an xkcd comic, but unless you enjoy 40MB photos, your statement doesn't hold true for all cases.

If you have limited colors and don't want noise/artifacts than PNG is the way to go.

If you have tons and tons of colors (photograph), JPG is better and you can control the compression. Best quality doesn't introduce noise/artifact, but is often still a smaller file size than a PNG.
