First, to be safe, convert the original icon to .ico using this converter .
Then for compatibility with several browsers (in particular, Internet Explorer) use:
<link rel="shortcut icon" href="http://www.yoursite.com/youricon.ico" />
Most browsers are smart enough to use any PNG / ICO named favicon.ico located at the root of your site, but this is not always reliable.
