The favicon, that small but mighty icon nestled in your browser tab, plays a crucial role in branding and user experience for any web application. For Angular developers, customizing this tiny visual element is a common and important task. It’s the first impression many users get of your application, even before fully loading the page, serving as a visual anchor in a sea of open tabs. Learning how to change Angular CLI favicon is a straightforward process that instantly elevates your project’s professional appearance and brand identity. This guide will walk you through the simple steps to update your Angular application’s icon, ensuring your web app stands out and reinforces your brand from the very first glance.

Understanding the Favicon’s Importance in Angular Projects

A favicon, short for “favorite icon,” is a small, typically 16x16 pixel image that represents your website or web application. It appears in various places, including browser tabs, bookmarks, history lists, and search results. While seemingly minor, this tiny graphical element is a powerful tool for visual branding and user recognition. In an Angular project, the default Angular logo serves as a placeholder, but replacing it with your unique branding is essential for a polished, professional look.

Beyond aesthetics, a well-chosen favicon significantly enhances the user experience. When users have multiple tabs open, a distinct browser tab icon helps them quickly identify and navigate back to your application. This improved navigability contributes to a smoother and more intuitive interaction. Furthermore, consistent branding across all touchpoints, including the favicon, builds trust and reinforces your application’s identity in the minds of your users.

Modern web development often involves Progressive Web Apps (PWAs), where favicons take on even greater significance. A PWA icon is crucial for how your application appears when added to a user’s home screen on mobile devices or installed as a desktop application. Using the Angular CLI, you can manage these assets efficiently, ensuring your application looks great across all platforms.

Preparing Your Custom Favicon for Angular

Before you dive into the code, you need a new favicon image. The quality and format of this image are paramount to ensuring it looks crisp and professional across various browsers and devices. While the traditional favicon.ico format is still widely supported, modern browsers also embrace PNG and SVG for better clarity and scalability. PNG files are generally recommended for their transparency support and widespread compatibility, while SVG offers vector scalability without pixelation.

When creating or selecting your image, consider its simplicity and recognizability at a very small size. Complex designs often become illegible. Common sizes include 16x16, 32x32, 48x48, and 64x64 pixels. For a comprehensive set of icons covering different devices and resolutions, you might even generate multiple sizes. There are many free online tools available that can help you convert an existing image (like your company logo) into the various favicon formats and sizes you might need. A popular choice is Favicon.io, which can generate all necessary files from text, an emoji, or an image.

Once you have your desired favicon file(s), typically named favicon.ico or favicon.png, you’re ready to integrate them into your Angular workspace. Remember, consistency is key; ensure your chosen icon aligns with your overall brand guidelines and visual identity.

Changing the default Angular project icon to your custom one involves a few straightforward steps. Follow this process carefully to ensure your new favicon displays correctly across all browsers.

To change the Angular CLI favicon, you need to replace the default favicon.ico file in your src directory with your custom icon and, if necessary, update the index.html file to point to the new asset. After making these changes, rebuild your Angular application and clear your browser cache to see the updated icon.

1. Prepare Your Custom Favicon File(s): Ensure you have your custom favicon file ready. For simplicity, let’s assume you have a favicon.ico file or a favicon.png file. If you have multiple sizes or different formats (e.g., for PWA support), place them all in a designated folder, typically src/assets/icons/ or directly in src/. For this guide, we’ll assume you’re using a single favicon.ico file.

2. Replace the Default Favicon: Navigate to the src/ folder of your Angular project. You will find a default favicon.ico file there. Delete this file and replace it with your custom favicon.ico file. Make sure your new file is also named favicon.ico. If your icon is a .png file, you can name it favicon.png instead, but you will need to update index.html accordingly in the next step.

3. Update index.html (if necessary): Open your src/index.html file. Inside the

   section, you will find a tag pointing to the favicon. By default, it looks like this: <link rel="icon" type="image/x-icon" href="favicon.ico"> If you replaced favicon.ico with your new favicon.ico, no change is needed here. However, if you chose a .png file and named it favicon.png, you would update it to: <link rel="icon" type="image/png" href="favicon.png"> For more advanced PWA icon sets, you might have multiple tags, each pointing to a different size or type. Refer to the Angular documentation on service worker configuration for details on PWA assets.

4. **Re Question & Answer :
   How can I change the default favicon that is set by the Angular CLI?

   I have tried many things, but it always shows the Angular logo as the favicon, even though I have deleted that icon (favicon.ico in src folder). It still shows, and I don’t know from where it’s loaded from.

   I have replaced that icon with another icon, but it still show the Angular logo:

   <link rel="icon" type="image/x-icon" href="favicon.ico"> 
   

   Make a png image with same name (favicon.png) and change the name in these files:

   index.html:

   <link rel="icon" type="image/x-icon" href="favicon.png" /> 
   

   angular-cli.json:

   "assets": [ "assets", "favicon.png" ], 
   

   And you will never see the angular default icon again.

   Size should be 32x32, if more than this it will not display.

   NOTE: This will not work with Angular 9

   For angular 9 you have to put favicon inside assets then give path like

   ``` ```
