title: Public service to convert bmp/gif/png/etc to jpg?
body: <p>Is there any public service which I can use to convert any of the common image formats (gif, png, bmp, tga, etc) to a jpg?  I'm looking for something I can use from within javascript, sending the image to whereever, then getting back a jpg I can use.</p>
  
  <p>I am not looking for something manual, where I can go to <a href="http://foo.bar.com" rel="nofollow">http://foo.bar.com</a>, manually upload the image, then manually save the returned jpg.  I'm looking for something I can use as an actual web service remotely.</p>
