A favicon is a small graphic representing your website in browser tabs, bookmarks, and search engine results pages. Traditional `.ico` files are being replaced by modern SVGs with `theme-color`, which offer more flexibility and scalability. Add an SVG favicon using `<link rel="icon" type="image/svg+xml" href="/favicon.svg">` and customize color scheme with `<meta name="theme-color" content="#hexcode">`.
Adding a modern favicon in 2025 involves using SVG format for scalability and flexibility, including multiple sizes (e.g., 16x16, 32x32, 64x64), and specifying the theme color with `theme-color`. Create your design using a vector editor, export different sizes from the same SVG file, add meta tags to your HTML, test on various devices and browsers.
Developers have two main options for adding icons and graphics to web pages: using the `<svg>` element inline or referencing an external file with the `<img>` tag. Inline SVGs offer flexibility, accessibility, customization, and performance benefits, but may increase HTML file size and be cumbersome to edit. External IMG tags keep HTML clean, allow caching, and are easy to swap, but limit customization and add HTTP requests.
