A favicon, short for "favorite icon," is a small image displayed next to the page title on a browser tab and is also used when bookmarking the page. It's a crucial part of your website's identity, often reflecting your brand's logo or a simplified graphic related to your web content.
Favicons are not just for aesthetics; they help users locate and identify your website quickly among a sea of tabs and bookmarks. When you create a favicon, you're crafting a visual cue that resonates with your audience, enhancing user experience and reinforcing brand recognition.
Imagine you have multiple tabs open in your browser; it's the favicon that often allows you to navigate to the desired page without having to read each tab's title. This tiny icon plays a significant role in the usability of your website.
Moreover, a well-designed favicon is an extension of your brand that can leave a lasting impression on your users. When you add a favicon that aligns with your brand's color scheme and design ethos, you're ensuring a cohesive and professional look across all platforms.
Favicons come in several formats and sizes to accommodate different devices and contexts. The most common favicon file is the ico file, which is an image container that can store multiple sizes of icons. This ico file is widely supported across all desktop browsers.
However, modern browsers also support png, svg, and gif formats for favicons. The png format is particularly popular due to its support for transparency and lossless compression.
When it comes to sizes, a variety of dimensions are used to ensure that the favicon appears crisp and clear on different platforms. The standard sizes for favicon files include 16x16, 32x32, and 48x48 pixels, which are generally used for browser tabs and bookmarks.
For Apple devices, apple touch icons are used, which are typically sized at 180x180 pixels to accommodate the high-resolution displays.

Browsers are designed to look for favicon files when a user visits a website. They use the link rel attribute within the html head section of your web page to locate the favicon icon. The href attribute specifies the path to the favicon file, which is usually placed in the root directory of the website.
Once the browser retrieves the favicon, it displays it in the tab or address bar, helping users to visually identify the website.
For different devices and contexts, browsers may look for specific favicon formats and sizes. For instance, apple touch icons are used when someone adds your website to the home screen on an Apple device. Similarly, manifest files can be used to define app icons for Android devices.
By providing a range of favicon files in the appropriate formats and sizes, you ensure a consistent and recognizable presence across all platforms and devices.

The first step in adding a favicon to your Next.js website is to design the icon itself. The design should be simple, recognizable, and reflective of your brand. Remember that this icon will be displayed in small sizes, so intricate details may not translate well.
Several online tools and services can help you create a favicon. These include favicon generators that allow you to upload an image and generate the required favicon files and formats. Some popular services offer features like previewing how your favicon will look in different browsers and generating the necessary HTML code.
Once you have your design, you'll need to export the favicon file in various sizes and formats to ensure compatibility across all devices and browsers. Common sizes for favicon files include 16x16, 32x32, 48x48, and for Apple devices, you'll need Apple touch icons at 180x180 pixels. Export your design in .ico, .png, and possibly .svg formats to cover all bases.
In Next.js, the public directory is where you place static files that can be accessed directly by the browser. This includes images, stylesheets, and your favicon files. The files within this directory are served at the root URL of your website.
Place your favicon files in the public directory of your Next.js project. This makes them accessible via the root URL, which is the default location where browsers expect to find favicon files. For example, if your favicon file name is favicon.ico, it should be located at public/favicon.ico.
Next.js provides a built-in Head component that you can use to modify the head of your HTML document. To link your favicon, you'll need to import the Head component and add the appropriate link tags within it.
1import Head from 'next/head'; 2 3export default function MyPage() { 4 return ( 5 <> 6 <Head> 7 <link rel="icon" href="/favicon.ico" /> 8 {/* Add additional link tags for other favicon files and sizes here */} 9 </Head> 10 {/* The rest of your page */} 11 </> 12 ); 13}
Within the Head component, use the link tag to reference your favicon file. The rel attribute should be set to icon or apple-touch-icon for Apple devices, and the href attribute should point to the location of your favicon file in the public directory.
To ensure that your favicon appears correctly on different devices, you'll need to specify multiple sizes and types using a series of link tags. Include the sizes attribute for icons that have specific size requirements, like the Apple touch icon.
After adding your favicon files and linking them in your HTML document, it's important to test that they are displayed correctly. Open your Next.js website in a browser and look for the favicon in the tab. You can also add the page to your bookmarks and check the icon there.
Different browsers and devices may handle favicons differently, so it's crucial to test across a range of them. This includes checking on both desktop and mobile devices, as well as ensuring that Apple touch icons appear correctly when the page is saved to the home screen on Apple devices.
If your favicon isn't appearing as expected, check for common issues such as incorrect file paths, missing sizes, or caching issues. Browsers often cache favicon files, so you may need to clear your browser cache or change the file name of your new favicon to ensure the updated icon is displayed.
With these steps, you can successfully add a favicon to your Next.js website, enhancing your brand presence and improving the user experience for your visitors.
Apple touch icons are used when someone bookmarks your website or adds it to their home screen on iOS devices. These icons are larger than standard favicons, providing a clear and detailed appearance on high-resolution screens. To cater to different devices, you may need to provide several sizes of Apple touch icons.
To add Apple touch icons to your Next.js project, you'll need to create the icon files in the appropriate sizes, such as 180x180 pixels for the latest devices. Place these files in your public directory and link to them in your HTML head using the link rel="apple-touch-icon" tag. Specify the sizes attribute to help the browser choose the correct icon.
1<Head> 2 <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png" /> 3 {/* Add additional apple touch icon sizes as needed */} 4</Head>
A manifest file is a JSON file that provides metadata about your web application to the browser. It includes information about app icons, the web application's name, and the start URL, among other settings. This file is particularly important for Android devices when your website is added to a user's home screen.
Create a manifest file with the necessary metadata and place it in your public directory. Then, link to this manifest file in your html head using the link rel="manifest" tag. This allows browsers to access the file and use the specified icons and settings.
1<Head> 2 <link rel="manifest" href="/manifest.json" /> 3</Head>
SVG (Scalable Vector Graphics) favicons offer several advantages, including scalability and the ability to change colors based on the browser's theme color. They are ideal for modern browsers that support vector graphics.
To add an SVG favicon, place your .svg file in the public directory and link to it in your html head. You can use the type="image/svg+xml" attribute to specify the file type.
1<Head> 2 <link rel="icon" type="image/svg+xml" href="/favicon.svg" /> 3</Head>
The mask-icon is a Safari-specific feature that allows users to pin your website to the tab bar with a stylized icon that adopts the color of the Safari theme. To implement this, you'll need an SVG file and you should specify the color attribute to define the theme color.
1<Head> 2 <link rel="mask-icon" href="/safari-pinned-tab.svg" color="#5bbad5" /> 3</Head>
By utilizing these advanced favicon techniques, you can ensure that your website's branding is consistent and visually appealing across a wide range of devices and browsers. These methods allow for a more customized and professional appearance, enhancing the overall user experience.
Incorporating a favicon into your Next.js project is more than just a touch of visual flair—it's an essential aspect of your site's branding and user experience. By following the steps outlined in this guide, you can design, implement, and test a Next.js favicon that not only looks great but also functions seamlessly across various devices and browsers.
