Note that in some cases, lossless compression can give you much better
results than jpg. Particularly if the original is a complicated line
drawing (high contrast). Also, if the original is using indexed colors,
it may be more efficient. And if the original is a b/w 1 bit/pixel image,
even more so.

Try to convert to PNG or GIF and check if those formats give you more
logical sizes - they work better with the mentioned image types.
