ShrinkIt... is your application larger than necessary because of needless data stored in image resources? What is making your PDFs four times the size they ought to be? More on this shocking discovery at 11!

Being a responsible and forward-thinking developer, you're probably good and ready for the day Mac OS X supports resolution independence so you use multilayer TIFFs and PDFs instead of flat bitmap images whenever possible.

I found a much better, free alternative which works in Mac OS X 10.6 Snow Leopard. Apple does offer to reduce file size using Preview, if you save the document as a new file and choose Quartz filter > Reduce file size.

It shrank some, it nearly doubled the size of others.
