🔹 What Is a Favicon, and Why Does It Matter?

A favicon (short for “favorite icon”) is the small image displayed next to your website’s title in browser tabs, bookmarks, history, and even search results. It’s also called a website icon or browser tab icon.

🔹 How to Add a Favicon in HTML

⭐ Basic HTML Favicon Code

Add the following <link> tag inside your HTML <head> section:

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

<!-- For PNG format -->
<link rel="icon" type="image/png" href="/images/favicon.png">

<!-- For SVG format -->
<link rel="icon" type="image/svg+xml" href="/images/favicon.svg">

<!-- For legacy support -->
<link rel="shortcut icon" type="image/x-icon" href="/images/favicon.ico">

Key Attributes:

  • rel="icon" or rel="shortcut icon" (for older browsers)
  • type="image/x-icon", type="image/png", or type="image/svg+xml" depending on your favicon file format
  • href attribute points to your favicon path

💡 Did you know?
If you place a favicon.ico file in your site’s root directory, most browsers will automatically detect it, but using the favicon link tag in your HTML head section is the best practice for favicon visibility and control.

🔹 Favicon Design Tips and Best Practices

🎨 Design Guidelines:

  • Keep it simple and legible at small sizes (16×16 px)
  • Use high contrast and minimal detail
  • Base your favicon image on a recognizable element of your logo for instant brand association.
  • Test your favicon icon on different backgrounds and devices

⭐ Pro Tip:
Use a favicon generator tool to create all required favicon sizes and formats from a single design.

🔹 Favicon for Mobile and Modern Devices

📝 Note:
To ensure your favicon displays correctly on mobile devices and as a home screen icon, consider providing multiple favicon sizes and using the appropriate HTML favicon link tags.

🔹 Favicon SEO and Browser Support

  • Favicons can appear in search results, bookmarks, and browser history, aiding site recognition and click-through rates.
  • Modern browsers support PNG, SVG, and ICO formats, but for full favicon browser support, always include an ICO file.
  • Favicon for bookmarks, history, and search results helps users quickly identify your site.

🔹 Troubleshooting: Favicon Not Showing?

❓ Why isn’t my favicon displaying?
✅ Common issues include:

  • Incorrect favicon path in the href attribute
  • Missing or misnamed favicon file
  • Browser cache preventing favicon update (clear cache or use a hard refresh)
  • Unsupported favicon file format or dimensions

⭐ Pro Tip:
Use favicon testing tools to check favicon visibility and favicon browser support across platforms.

🔹 Favicon Tools and Generators
