It has a pstopdf utility which is roughly the same as ps2pdf from Ghostscript.

If you want rasterized graphics though, you've got to open it in Preview and 
save it as some other format. Conceivably you could write some AppleScript to 
make Preview do this for you from the command line, but I don't envy the person 
who takes that on.
