PNG (portable network graphics) and JPEG formats are very
common on the web. Gif is not such a good format on the web,
because gif is fat.

Different formats of the same stata graph, with size:

  tata.eps   9981 
  tata.png   6919 
  tata.jpg  11114 
  tata.gif 115882 
  
My stata knows about PNG, but only from the menu (unless I
missed something). -graph export tata.png, as(png)- does not
work. In any case, imagemagick <http://www.imagemagick.org>
does the conversion between 68 major formats for free, and
runs also under MS-windows.
