How about ImageMagick's convert program:

And don't forget to have a look at all the options in "man comvert" for enhancing/smoothing/etc (you may need to look up "man ImageMagick" to get explanations of some of them).
The -quality option is often worth setting when working with JPEGs - the default can be a bit low for some purposes IME. But remember that you're not going to "get back" anything lost in previous JPEG compression.
