Ghostscript is your friend here. You can use the pngalpha[1] device:

gs -dNOPAUSE -r200 -sDEVICE=pngalpha -sOutputFile=file.png -dBATCH file.pdf

(gswin32c on wWndows)

If you want to crop the ps file as well, there was recently a long
thread about this on comp.text.tex [2]. You may also find a few tips
here [3]
