Why Are My Favicons Blurry?

Blurry favicons are usually caused by incorrect size implementation. Here's how to ensure crystal-clear icons:

Troubleshooting: Common Display Issues

Here are solutions to frequent favicon problems:

  • Favicon not showing: Add this line in your HTML head: <link rel="icon" type="image/png" href="/favicon.png">
  • Old favicon persisting: Add ?v=2 to your favicon URL to bypass cache
  • Blurry on mobile: Include the 192x192 and 512x512 sizes
  • Missing from bookmarks: Ensure you have the 32x32 size

Quick Fix Guide: Missing or Broken Favicons

Follow these steps to fix favicon issues:

  • Verify your favicon files exist in the correct location (usually root directory)
  • Check your HTML implementation (see example code below)
  • Clear your browser cache and reload
  • Test in incognito/private mode to rule out caching issues

Example of minimal HTML implementation: 


<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="manifest" href="/site.webmanifest">

Dark Mode Support: Modern Best Practices

Implement dark mode support using this code: 

<link rel="icon" media="(prefers-color-scheme: light)" href="/favicon-light.png">
<link rel="icon" media="(prefers-color-scheme: dark)" href="/favicon-dark.png">

Create two versions of your favicon with appropriate contrast for each mode.

  • Implementation: Add <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

Performance Tips: Optimizing Favicon Delivery

Follow these best practices for optimal performance:

  • Compress PNGs using tools like TinyPNG
  • Use cache headers: Cache-Control: public, max-age=31536000
  • Lazy-load larger sizes using the media attribute
  • Consider using SVG for better compression and scaling

Using only favicon.ico limits your site's capabilities. Here's what you need for modern web standards:

  • High-Resolution Support: Include PNG versions for crisp display on modern screens
  • Mobile Optimization: Add specific sizes for iOS and Android devices
  • Modern Features: Implement manifest.json for PWA support and advanced features

Testing Your Implementation

After implementing your favicon, test it in these scenarios:

  • Browser tabs and bookmarks bar
  • Mobile home screen (iOS/Android)
  • Dark and light mode
  • Different browsers (Chrome, Firefox, Safari, Edge)
  • PWA installation
