I've made this web application primary to get favicons as PNG files (okay, originally gif, but this PHP version does not support this) without having to start Photoshop. Now it's a database driven tool, which allows you to view hundreds of favicons and add your own. You can use any favicon displayed to place it next to the related URL. Please do not steal them and say you made them.
Note: Some favicons seem to be somehow special. Unfortunately those are cyan in the current version and cannot be used they look strange and are useless. If you think you can improve this, contact me.
* New: Support for transparency added
SELECT id, url FROM faviconverter ORDER BY `usage` DESC, date LIMIT 1000
