According to the man page (and my own past experiences, I seem to recall),

	convert -geometry 640x480 in.jpg out.jpg

converts the image to have a maximum width of 640 and a max height of
480 _and_ keeps the aspect ratio. (If you don't want to keep the aspect
ratio, you need to add an '!' to the end of the geometry.)
