Import from http to graphic pdf

Good morning everybody, My problem is as following:
What instruction or comand would I have to write in Mathematica in order to import a http file from Wikipedia in graphic PDF format? What I use to write is :

popo = Import ["http://es.wikipedia.org/wiki/vikingos"]
popo = Import ["http://es.wikipedia.org/wiki/vikingos", "Source"]

In this way the output comes in plain text and I need it in graphic PDF file as I said above.

Thank you very much

Your sincerily
