Is there a way to create smaller, better PDFs? As just one example, I have a Powerpoint PPTX that is about 3MB. Saved or printed to PDF it's over 6MB. If I open it in Preview and re-save with the Quartz filter to reduce file size, it's still 5MB. The same presentation saved to PDF on Windoze about the same size, if not smaller, than the original Powerpoint! And to add insult to injury, the Mac-produced PDF looks worse both in Acrobat on the Mac and anything on Windows. Has anyone compared the built-in Mac PDF output to Acrobat? Are there other tricks or drivers out there to make smaller PDFs?
