ICO is an image file format for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, allowing them to be scaled appropriately.
Add this code to your HTML <head> section:
<link rel="icon" type="image/x-icon" href="/favicon.ico">Use the ICO file as your application icon in your development environment (Visual Studio, etc.).
Recommendation: Use ICO for maximum compatibility, or provide both ICO and PNG versions.
For website favicons, include 16×16, 32×32, and 48×48. For Windows applications, also add 64×64, 128×128, and 256×256 for high-resolution displays.
