From the developer:
Faviconer is for creating favicons for websites (the site icon you see in browsers' favorites). The app is simple and intuitive. You just need to select the source image, choose the required icon size, click a button, and the favicon is ready. Faviconer supports most commonly used image formats: .psd, .ai, .png, .tiff, .gif, .jpg, .icns, and many others.
You may want to check out more software for Mac, such as Image to icon, Faviconographer or iOS Icons, which might be similar to Faviconer.
