Hi Oliver,

This is called "font subsetting". Gropdf does not do that at the moment so the 
size can be substantially reduced by running the pdf through ghostscript's 
ps2pdf, if the pdf contains large embedded fonts. I say "at the moment", watch 
this space, but it won't be in the upcoming 1.23.0.
