Free utility from Panic; losslessly shrinks PDFs by running them through Mac OS X’s built-in PDF engine.

...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.

ShrinkIt is a simple, small, Panic-internal tool (for Mac OS X Snow Leopard) that will automate the process of stripping needless metadata from PDFs by re-saving them using Apple’s PDF processor. We believe this is 100% lossless — it’s not compressing anything, just removing cruft. Simply drop a bunch of files (not folders) onto it — such as the contents of your app’s Resources folder — to have it find the PDFs and do its magic. The original files will be renamed with the prefix “_org_” for safety, but you’ll likely want to delete ‘em. That’s it!
