How do I create a .ICO file?

To resize desktop icons, right-click (or press and hold) the desktop, point to View, then select Large icons, Medium icons, or Small icons .

You can either compress/reduce the filesize of the icon (I recommend using ImageMagick to do this, you can download it here), or you can make the dimensions smaller. However, if you are putting an ico file on a website I recommend using a different image format, such as . png.
