This tool converts an image into a proper .ico file - the format browsers and operating systems expect for favicons and desktop shortcuts. Modern favicons often need multiple sizes bundled into one .ico file so it looks sharp everywhere from a browser tab to a bookmark.
Frequently asked questions
Start with a square image, ideally at least 256x256 pixels, so the generator has enough detail to produce sharp icons at all the smaller sizes bundled into the .ico file.
A proper favicon .ico typically bundles several sizes (like 16x16, 32x32, 48x48) into one file, so the browser/OS can pick whichever fits the context.
Favicons are expected to be square - a non-square source image will typically be cropped or padded to fit a square canvas before generating the icon sizes.
