React – How to Add Favicon

A favicon is the small icon displayed in the browser tab next to the title of your webpage. Adding a favicon to your React application enhances your application’s branding and user experience.

Steps to Add a Favicon in React

Step 1: Prepare your favicon. Ensure your favicon is in the correct format (usually .ico, .png, or .svg) and saved with a square resolution, such as 32×32 pixels.

Step 2: Place your favicon in the public folder of your React application. This folder is ideal for static assets that need to be accessible directly.

Step 3: Update the index.html file to include the favicon and ensure it is recognized by the browser.

Steps in Detail:

Step 1: Place the Favicon in the Public Folder

Copy your favicon file (e.g., favicon.ico or favicon.png) to the public folder of your React project.

Step 2: Update the index.html File

Open the public/index.html file and add the following line inside the <head> section:

</>
Copy
<link rel="icon" href="/favicon.png" />
Step 3: Verify the Favicon in the Browser

Run your React application and check the browser tab to ensure the favicon is displayed correctly. If necessary, clear the browser cache to load the updated favicon.

Explanation

  • The public folder is used to serve static assets directly, ensuring that the favicon is accessible at /favicon.png.
  • The <link rel="icon"> tag in the index.html file explicitly tells the browser where to find the favicon.
  • This method ensures the favicon is immediately recognized without needing additional configurations.

Best Practices

  • Use a 32×32 pixel or higher resolution for your favicon for better clarity.
  • Include multiple formats (e.g., .ico, .png, .svg) to support a wider range of devices and browsers.
  • Always test the favicon on multiple platforms to ensure proper functionality.

Conclusion

Adding a favicon to your React application via the public folder and updating the index.html ensures consistent behavior across browsers and platforms. By following these steps, you can enhance your application’s branding and user experience.
