Are you tired of using the default favicon provided by Next.js? Do you want to add a personal touch to your website’s identity? Look no further! In this comprehensive guide, we’ll walk you through the process of changing the favicon using Next.js. By the end of this article, you’ll be able to replace the default favicon with a custom one that reflects your brand’s personality.
What is a Favicon?
Before we dive into the tutorial, let’s quickly cover the basics. A favicon (short for “favorite icon”) is a small icon or image that represents a website or web page in a browser’s address bar, bookmarks, and search engine results. It’s a small but significant element that helps users quickly identify your website and adds a touch of professionalism to your online presence.
Why Change the Default Favicon?
The default favicon provided by Next.js is, well, basic. It’s a simple black and white icon that doesn’t do much to differentiate your website from others. By changing the favicon, you can:
- Establish a strong brand identity
- Enhance user experience
- Differentiate your website from others
- Showcase your creativity and attention to detail
Step 1: Create Your Custom Favicon
Before we start coding, you’ll need to create a custom favicon. You can use a tool like Adobe Photoshop or Canva to design a 16×16 or 32×32 pixel image. Save the file in a format like .ico, .png, or .jpg.
For the purpose of this tutorial, let’s assume you’ve created a favicon called “custom_favicon.ico” and saved it in the same directory as your Next.js project.
Step 2: Add the Favicon to Your Next.js Project
In your Next.js project, create a new folder called “public” if it doesn’t already exist. Inside the “public” folder, create another folder called “icons”. This is where you’ll store your custom favicon.
PROJECT STRUCTURE: my-next-project/ components/ ... pages/ ... public/ icons/ custom_favicon.ico next.config.js package.json ...
Step 3: Update next.config.js
In your “next.config.js” file, add the following code to specify the custom favicon:
module.exports = {
//...
async headers() {
return [
{
source: '/icons/custom_favicon.ico',
headers: [
{
key: 'Cache-Control',
value: 'public, max-age=31536000',
},
],
},
];
},
};
This code tells Next.js to serve your custom favicon from the “public/icons” folder and cache it for a year (31536000 seconds).
Step 4: Update head.js
In your “pages/_app.js” file or “components/layout.js” (depending on your project structure), add the following code to the `Head` component:
import Head from 'next/head';
function MyApp({ Component, pageProps }) {
return (
<>
<Head>
<link rel="icon" href="/icons/custom_favicon.ico" />
</Head>
<Component {...pageProps} />
</>
);
}
export default MyApp;
This code adds a `link` tag to the `Head` component, specifying the custom favicon’s relative URL.
Step 5: Verify Your Favicon
Start your Next.js development server using `npm run dev` or `yarn dev`. Open your website in a browser and check the address bar – you should see your custom favicon instead of the default one!

Troubleshooting Tips
If you’re having issues with your custom favicon not displaying, try the following:
- Check the file name and path: Ensure that your custom favicon is named correctly and stored in the correct location (i.e., “public/icons/custom_favicon.ico”).
- Verify the file format: Make sure your favicon is in a supported format like .ico, .png, or .jpg.
- Clear browser cache: Sometimes, browsers cache the default favicon. Try clearing your browser cache or using a private browsing mode to verify your custom favicon.
- Check for syntax errors: Review your code for any syntax errors or typos that might prevent the favicon from displaying.
