Of course, a converter for base64 and others could be written
in TeX^1. But the result would have to be written in temporary
external files and be input as image via \includegraphics.
  But I don't see the point of this exercise, you have such
a converter already in a much more efficient programming
language than TeX.

^1 Some conversions already are written, e.g. for encoding and
   decoding hex dumps: package `pdfescape'.
