I remember this from the the original hacker news thread and still use it. Anything 'real' gets custom rendered icons for each size, but for side projects where the icon quality isn't critical it's very convenient.

For reference, the original HN thread: https://news.ycombinator.com/item?id=4529963

Looks useful, thanks for the link. In case its news to you, with iOS7, a few more suggested dimensions have been introduced than what is available on allthefavicons.com at the moment. More details at the cheatsheet.

Cheers. I may integrate the changes in the cheatsheet one day if i ever get round to updating my old side projects. :)

Can you open source this so I can beef it up please?

Edit: Actually, I just realized I can probably build this in a weekend with image magic.
