OK, first you need to decide what you wish to convert to - another page layout program (such as Quark) or a drawing program (such as Illustrator). I guess that depends on why you want to do the conversion.
Secondly, PDF may be the way to go, but you cannot edit a PDF placed in Quark. I think you can edit a PDF opened in AI.
To make the PDF, you need to have Acrobat. Do you have this program, or something similar?
