They're part of OS X, period. It's essentially Objective-C code written using AppleScript: AppleScriptObjC.

If you're talking PDFs for pre-press, I'd stick to Acrobat Pro. This is basically using the code that apps like Preview use; the results are PDF 1.3.

I only tested it on a document with 100-odd pages, but it shouldn't take more than a couple of seconds for you to test it on the real thing.

If it's a one-off, then there's probably no point redoing that. But again, that would be relatively simple enough to incorporate as AppleScriptObjC code.

Simple: copy the code into a script editor's window, and hit the Run button.
