Favicon Generator: favicons made easy
Generator mode is where you can upload your gifs, jpgs and pngs to be converted. The Generator will resize them to the standard 16x16 pixel favicon size for you, but you can easily get a full-sized .ico instead by clicking a checkbox. In Editor mode, you draw your own icon on an oversized 16x16 grid, using any web colors you like. There's no option to enlarge the grid, so this is no solution for serious pixel-art projects. When it comes to favicons, though, it's the perfect tool for the task.
