<p>I am serializing a <code>JPEG</code> Image in <code>c#.net</code>. I am simply converting it into a byte steam and sending it through web service. </p>

<p>I observed that serialized byte stream is 30 times more than that of the size of actual image. Can any one <strong>suggest me a better approach</strong> to serialize and stay relative to the size of the actual image?   </p>
