No point in fiddling around with Quartz filters: Preview will Save As a
variety of graphics formats.
GIF is the smallest (but is only suitable for screen captures).
PNG is the next smallest: about a 20th of the size of BMP, and is very good
for screen shots and line drawings.
JPG enables you to specify a "Quality" rating that enables you to specify
the size of the output file: from "large" to "very small". When you reduce
the quality, you are removing detail from the image, so save as a copy and
test to learn how low you can set the quality without wrecking your image.
This is best done with a proper graphics editor that also enables you to
crop the image and to adjust the resolution. For screen-based display,
there is no point in setting the resolution above 96 pi. If you set it that
low, you will save a huge amount of file size, regardless of which of the
above formats you choose.

Apple's PDF generator is a space hog. In general, when I compare pdfs
generated by Apple's pdf they are 10 times the size of the same pdfs
genenrated by Adobe Acrobat professional on my PC. 10 times! That doesn't
matter from what source: word, .ps, .eps etc. So, if you're interested in
compact pdfs I would recommend trying Acrobat professional.
If you have bitmap images in your document, you can reduce the file size by
opening in Apple's preview and using save as and applying a quartz filter
(reduce file size). I find that Apple's standard filter makes the image
quality very poor, but you can define your own filters in colorsync utility
(yes, this is kind of complicated; this part of OS X is not that user
friendly).
