Need a document converter that doesn't require downloading?

Here you go! Docupub.com I'm creating .pdfs of my cat posters that I can email to friends to post on their driver's side back seat window to help get my long-termers out of here. All I had to do was upload my .jpg of the poster and then save the .pdf it returned to me in my browser. They also have an email version. I have not tried that.
