What do you mean? Do you mean that the Mac OS X specific xdv2pdf  
creates with PNG inclusions a larger PDF file than xdvipdfmx? The PNG  
contents can be compressed by xdvipdfmx or pdfTeX, too, I think, up  
to the maximal value as set in their DEF or CFG files. Then both  
convertors create different versions of PDF: 1.4 vs. 1.3. I think PDF  
1.4 has learned LZW compression for "stream" objects, which can be  
better than the default FLATE. Some space (a few 100 bytes...1 K) can  
be saved by concatenating command chains, i.e. /a /b /c /d /e can  
become /a/b/c/d/c: five bytes saved!
