I'll just send an image and not bother with a PDF.

(Note there's also other metadata in a PDF, which you may not want your recipient to know either.)

There's also metadata in the image files. What specifically would be sensitive in the pdf with screenshots metadata that is also not present in the sceenshot image metadata?

		PDF has something called an "info dictionary", which most mainstream PDF-writing software will fill out with various bits of info that you might not want known. Image files usually have substantially less metadata by default, unless it's one taken by a camera.
