Replace font in PDF

Question

Is it possible to replace the (embedded) font in a pdf file? I tried Acrobat, but there I can just replace the paragraph. I want to replace every word with this font in the full document.

Perhaps perhaps with ghostscript or something like that?

Answer 1

Infix Pro can do it
