If you're using the Mac's built-in PDF generator, there is a HUGE difference in filesize between different browsers' output.
How do you mean? (I'm not too familiar with Macs.) Filesize in what the end user sees when viewing the PDF in the browser? Or filesize when actually creating the PDF (in browser?)? Having looked at a few of the PDFs, they seem to have been generated mostly with InDesign CS3/CS4.
