(translated from french)
Creating an icon can take more time than it seems. This is what it's always great to have tools that can automate the whole process and make it lighter on you.

ToYcon lets you create icons by simply dragging and dropping images onto its box-shaped interface. The program supports all the popular graphic formats and converts them right to ICO as soon as you drop the file on its interface. The resulting icon is saved in the same folder as the original image with the same name, though you can set the program to ask for destination after each conversion.

Despite its simplicity, ToYcon is quite a handy tool with support for several sizes and color depths. It doesn't really have many configuration options but it's very easy to use and works fine. Plus it doesn't require installation, so you can simply unzip the archive wherever you want to save the program and you're ready to go.

ToYCon is probably the easiest and fastest way to generate icons from your image files.
