Convert ICO 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.


    I tried this PHP class, but it tends to generate a lot of noise in PNGs for some favicons:

    controlstyle.com/articles/programming/text/php-favicon/


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


    Thanks for your help!

    I know PHP can turn a PNG, JPG, BMP and GIF image into almost any other image (via headers).

    What you could try doing is getting the code from the ICO and sending it back as a PNG.

    
<?php
header("Content-Type: image/png");
echo file_get_contents("file.ico");
?>
    PHP:
    It most likely will not work, but you could give it a go :)

    If that files, look for a shell script that does this.

    You're fooling the browser this way. PHP doesn't do any changes on the image and doesn't convert anything. And if it works, it may not work on all browsers.

    For ICO stuff, I always use the net NetPBM library via exec() calls. Messy (and can load the CPU), but reliable.

    Also, there's a native PHP library for ICO manipulation, but I don't remember what it's called. You can search for it at sourceforge.net

    Sorry for digging up this thread but I thought this one may help visitors who have searched through Google to here for an answer.

    If you are just an end user you may use this online image converter that converts .ICO to .PNG and vice versa.

    Actually it does much more than an ordinary one-way image converter. It's almost an all-image converter that converts between all common image formats.
