-size has no effect here.  -resize would be better, but the size of 
the pdf is controlled by -density as it is a vector format.

logo: image is 640x480

using -density 72 will produce the same size pdf
using -density 144 will produce half that size pdf

convert logo: -density 72 logo1.pdf
convert logo: -density 144 logo2.pdf
identify logo1.pdf logo2.pdf
