Thanks to Max & Romain for noting alternative methods.

As mentioned in my original post, I've tried the png->imagemagick- 
 >gif solution and was displeased with quality of the results (using  
default quality values at least).

Additionally, I disliked the idea (shared with the menconder method)  
that part of the process involved the creation of a large number of  
intermediary files which would then have to be deleted at some point.  
I know 'rm *.png' is as easy as 'rm mypdf.pdf', but the difference in  
forgetting to do this, from the perspective of gui file browsing at  
least, is significant.
