About ICO Converter
An ICO file is the classic format for a website favicon and for Windows icons. Upload an image, such as your logo, tick the sizes you want (16, 32, 48 and 64 pixels), and the tool builds a single favicon.ico that contains every size you chose, so the browser or system can pick the sharpest one.
Images that are not square are placed in the middle of a transparent square instead of being stretched, so your logo keeps its proportions. Transparent areas are kept. For the best result, start with a square image that is at least 64 pixels wide, with a simple design, because small icons lose detail.
Put favicon.ico in the root of your site or link to it from the head of your pages. Modern browsers also accept PNG and SVG favicons, but an ICO file still works everywhere, including older browsers and some tools. The conversion happens in your browser and your image is not uploaded.
