Hiya,
'pngcrush' (commandline option) can do this as well as
'imagemagic' (also commandline).
imagemagick: convert pic.png -background white -flatten +matte
pic_new.png
Unless what you want to do is get it into indexed (palette) mode and
remove the alpha channel from there.
png2pdf might be an option, it can take care of the alpha channel and
give you a pdf, which you can embed into a pdf
(http://png2pdf.sourceforge.net)
Cheers,
Luis.
