Replace Font in PDF

Question

is it possible to replace a (embedded) font in a pdf-file? I tried Acrobat, but there I just can replace paragraph by paragraph. I want to replace every word with that font in the complete document.

Maybe possible with ghostscript or anything like that?

Answer 1

Infix Pro can do it
