HTML Favicon: Add a Site Icon
Learn how to add a favicon with a link element in the document head and choose an icon file for your website.
What a favicon is
A favicon is an icon associated with a website. Browsers may show it in tabs, bookmarks or other browser interface areas.
Link an icon in the document head
Use a <link> element inside <head>. A root-relative path can point to an icon at the website root.
<head>
<meta charset="utf-8">
<title>Example page</title>
<link rel="icon" href="/favicon.ico">
</head>
The rel="icon" value identifies the resource as a site icon. The href gives its URL. Browsers support common icon formats; check the requirements of the browsers and platforms your site serves.
