Thanks.

It's an easier way to expand the pdf, and remove incompatible security, fix incompatible images, etc.

It's not so good for compressing the pdf. 150 dpi sometimes yields jagged lettering, and 72 dpi consistently yields jagged lettering.

On the Mac 300 dpi in k2pdfopt and 72 dpi in a quartz filter usually does all right.
