Convert ICO (favicons) to PNG or GIF?

Is there a script to convert ICO images to PNG or GIF?

I'm looking for a PHP script (or anything server-side) that can convert ICO images (favicons) to either PNG or GIF.

Anyone know of a script that converts ICO to PNG or GIF?

Thanks for your help!

ImageMagick support this and can be integrated on the server-side with ease. Many tutorials going for using ImageMagick with PHP.
