Question - How do you Save a Photobucket file to PDF?

[pugpup]

Good Morning:
I have contacted a printer who will print, however they only use PDF. I have a MAC and when I downloaded the Photobucket files, they only open in my Preview. I can use the Save As option from Preview to change it to a PDF, however I'm not sure if the file is as "crisp" as the original in Preview. Can anyone advise?
Thanks!!!

Be sure the printer is not printing Disney images in violation of Disney copyrights.....a concern to many of our DISigners
