Favicon Guide: Creating Icons for Modern Browsers

Favicon Guide: Creating Icons for Modern Browsers

The favicon is one of the smallest but most recognizable parts of your website. That tiny icon in browser tabs helps users identify your site among dozens of open tabs. Getting it right matters.

What Is a Favicon?

Short for "favorite icon," the favicon appears in:

  • Browser tabs
  • Bookmarks and favorites
  • Mobile home screen shortcuts
  • Browser history
  • Search results (sometimes)

Create yours with our favicon generator.

Essential Favicon Sizes

Modern websites need multiple sizes:

Minimum Required

  • 32×32 pixels: Standard browser tab icon
  • 16×16 pixels: Very small displays

Recommended Additions

  • 180×180: Apple Touch Icon (iOS home screen)
  • 192×192: Android Chrome
  • 512×512: Android PWA splash screens
  • 150×150: Windows tiles

Favicon Formats

ICO (Traditional)

  • Contains multiple sizes in one file
  • Maximum compatibility
  • Supported everywhere including older IE

PNG

  • Modern standard
  • Supports transparency
  • Crisp at all sizes
  • Separate file per size

SVG

  • Scales perfectly to any size
  • Smaller file size
  • Limited browser support for favicons
  • Good for high-DPI displays

HTML Implementation

Basic setup in your HTML head:

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

<!-- PNG versions -->
<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
<link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">

<!-- Apple Touch Icon -->
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

<!-- Web App Manifest (for Android) -->
<link rel="manifest" href="/site.webmanifest">

Design Best Practices

Keep It Simple

At 16×16 pixels, detail is lost. Use:

  • Simple shapes
  • Bold colors
  • High contrast
  • Single letters or icons

Test at Small Sizes

Design at large size but check at actual favicon size. What looks good at 512px might be unrecognizable at 16px.

Consider Dark Mode

Light favicons disappear on dark tab bars. Add borders or use colors that work on both light and dark backgrounds.

Match Your Brand

Use your logo, brand colors, or a recognizable element from your visual identity.

Common Favicon Mistakes

  1. Too complex: Intricate details become muddy at small sizes
  2. Wrong format: Using JPEG (no transparency support)
  3. Missing sizes: Only providing one size looks blurry elsewhere
  4. Poor contrast: Invisible against certain backgrounds
  5. Forgetting touch icons: Mobile shortcuts look unprofessional

Web App Manifest

For PWAs and Android home screen icons, create site.webmanifest:

{
    "name": "My Website",
    "short_name": "MySite",
    "icons": [
        {
            "src": "/android-chrome-192x192.png",
            "sizes": "192x192",
            "type": "image/png"
        },
        {
            "src": "/android-chrome-512x512.png",
            "sizes": "512x512",
            "type": "image/png"
        }
    ],
    "theme_color": "#ffffff",
    "background_color": "#ffffff",
    "display": "standalone"
}

Testing Your Favicon

  • Check in multiple browsers (Chrome, Firefox, Safari, Edge)
  • Test on mobile devices
  • Add to home screen on iOS and Android
  • Verify in incognito/private mode (no cached version)
  • Check both light and dark mode tabs
