If this is the problem, whoever generated the JPEG must have used an
extremely low quality setting. JPEG's loss is controllable. And GIF
is not lossless, because the step of quantizing to a 256-color palette
causes far more loss for a full-color image than JPEG does.

Yes, except for animations PNG totally dominates GIF (except that only the
latest browser versions support it).
