Convert PDF to PNG using ImageMagick

Question

using ImageMagick  what command should i use to convert a PDF to PNG  I need highest quality  smallest file size  this is what I have so far  very slow by the way    convert -density 300 -depth 8 -quality 85 a pdf a png   Looking at what Gmail does when a user  view  a PDF  the quality is awesome and the file size very minimal  The DPI is just 96  I have to set a density of 300 to get anything decent   Anyone know how GMail does it  Thanks

when you set the density to 96  doesn t it look good   when i tried it i saw that saving as jpg resulted with better quality  but larger file size

Reducing the image size before output results in something that looks sharper  in my case   convert -density 300 a pdf -resize 25  a png
