Bursting PDFs in individual GIF files?

I have a  number of lengthy PDF documents ­­ seminar presentations 
actually ­­ in which the individual pages contain primarily text and 
vector graphics originally generated in Illustrator or from other 
PostScript sources.

I want to burst/ex****t/save/extract the individual pages of these 
dcuments as images, to be used as individual pages on a web site (i.e., 
in an HTML gallery).

I've been led to believe that GIF is the best and most compact format 
for displaying text and line art images of this type on the web -- but 
Acrobat only seems to be able to ex****t individual pages to JPEG format.

Is this correct?  Any easy way around the problem?  If I go through a 
two-step process, PDF -> JPEG -> GIF, have I already lost the image 
sharpness of the GIF format?  Can GraphicConverter convert individual 
PDF pages directly to GIF?

Or should I just stay with the JPEG images?  (which don't seem that bad, 
actually)
