If you're looking for an online utility to convert JPEG, PNG, or GIF images to ICO format, here's one that does exactly that. It supports full transparency when converting 24-bit PNGs and even lets you combine multiple resolutions into one icon file — perfect for generating favicons.

The name of the tool is ICO Converter and, while the design of the page isn't very flashy, it works exceptionally well. Give it a try and start making some icons!
