A great utility. Thanks Mipey
There is another utiliity for windows called Real world icon editor.

It makes all of the icon sizes automatically for windows. It also allows you to poke the icons directly into the EXE files. This is AWESOME for people who use the Node Webkit exporter.
I have this ConvertIcon webpage bookmarked. It was nearly impossible for me to find a converter for my ChromeBook. Thanks again this will come in really handy <img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt=":D" title="Very Happy" />
