For those of you on Macs and without Acrobat, there's a modestly priced 
app called PDF Shrink, from Apago, which does the same thing. I've used 
it for a month or two now, and been quite happy with it.

It can be handy, in fact, even if you have Acrobat, since it allows you 
to specify different levels and types of shrinkage (e.g., choose the 
resolution for pixel graphics, chose how much metadata to remove); make 
a named icon for each of these choices; chose a string to be added to 
the file name applying each of these choices; and then activate any of 
the choices by just dragging the source file onto that icon.
