Not so.  On many Linux distributions it is not installed unless some
other product depends on it.  It is fairly small (528Kb Intel bin) and
so placing a dependency on it does not seem to me to be a worry.

Last I checked, netpbm is the best for this sort of stuff.  Rather than
write a converter from any image format to any other, netpbm solves the
issue by adopting a common intermediate format, and supplying converters
to and from that format.
