Submitting PDF Porftolio for Internship? (I only have a website) [on hold]

I'm submitting an application for an internship. It's asking for my website and a pdf of my portfolio. I don't have a pdf portfolio, what should be chosen from my website to put on it?

It can't have all the info from my website, that would be an enormous document because I explain the process of everything. So maybe just featured work? Any advice would be great.
