CANON · Favicons

Favicons are the smallest piece of branding and the most often botched. Modern browsers need multiple sizes, formats, and declarations.

The minimal set

<link rel="icon" href="/favicon.ico" sizes="32x32">
<link rel="icon" href="/icon.svg" type="image/svg+xml">
<link rel="apple-touch-icon" href="/apple-touch-icon.png">
<link rel="manifest" href="/manifest.webmanifest">

Files to generate

File	Size	Format	Purpose
`favicon.ico`	32×32 (can embed 16×16)	ICO	Legacy browsers, bookmarks bar
`icon.svg`	Scalable	SVG	Modern browsers (Chrome, Firefox)
`apple-touch-icon.png`	180×180	PNG	iOS home screen
`icon-192.png`	192×192	PNG	Android home screen, PWA
`icon-512.png`	512×512	PNG	PWA splash screen

SVG favicon with dark mode

SVG favicons can adapt to dark mode:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
  <style>
    rect { fill: #0a0a0a; }
    @media (prefers-color-scheme: dark) {
      rect { fill: #f5f5f5; }
    }
  </style>
  <rect width="32" height="32" rx="4"/>
</svg>

Web app manifest

{
  "name": "My App",
  "short_name": "App",
  "icons": [
    { "src": "/icon-192.png", "sizes": "192x192", "type": "image/png" },
    { "src": "/icon-512.png", "sizes": "512x512", "type": "image/png" }
  ],
  "theme_color": "#0a0a0a",
  "background_color": "#ffffff",
  "display": "standalone"
}

theme_color affects the browser toolbar color on Android.

Design rules

Simple at 16px. If your logo doesn't read at 16×16, simplify it to a lettermark or geometric shape.
No text at small sizes. Text is illegible below 32px.
High contrast against both light and dark browser chrome. Test on light and dark OS themes.
Square. All favicon slots are square. Don't force a horizontal logo into a square; make a square variant.
No transparency for apple-touch-icon. iOS fills transparent areas with black. Use a solid background.

Anti-patterns

Anti-pattern	Why it fails
Only a 16×16 favicon.ico	Blurry on retina, missing from home screens
Full logo crammed into 32px	Illegible
Transparent apple-touch-icon	Black background on iOS
No manifest for PWA	Missing home-screen icon on Android
favicon.png instead of .ico for legacy	Some browsers only check .ico
No SVG favicon	Missing dark-mode adaptation

Audit checklist

favicon.ico at 32×32
SVG favicon for modern browsers
apple-touch-icon.png at 180×180 (no transparency)
192px and 512px PNG for PWA manifest
manifest.webmanifest linked in <head>
Icon reads clearly at 16×16
Tested on light and dark browser chrome
theme_color and background_color set in manifest
