Favicon & Web App Manifest Checker

Audit website favicon implementations across modern browsers, iOS home screen touch icons, SVG dark-mode favicons, and Progressive Web App (PWA) manifest configurations.

Modern Favicon & App Icon Implementation Standards

Favicons are small visual brand identity icons displayed in browser tabs, bookmark bars, mobile search snippets, and mobile home screen shortcuts. In modern search engine results pages (Google Mobile & Desktop SERP), Google displays a 16x16 pixel favicon next to the domain name, making a valid favicon a critical factor in search branding and click-through rates.

Recommended Favicon Asset Inventory

  • /favicon.ico (Legacy Fallback): A multi-resolution .ico file containing 16x16, 32x32, and 48x48 pixel icons placed at the web server root.
  • /apple-touch-icon.png (180x180): High-resolution PNG used by Apple iOS Safari when users save web pages to their mobile home screen.
  • Vector SVG Favicon (/favicon.svg): Scalable vector icon supporting @media (prefers-color-scheme: dark) for automatic dark mode adaptation.
  • Web App Manifest (manifest.json): Declares 192x192 and 512x512 PNG icons for Progressive Web App (PWA) installation.

Standard HTML Link Tags for Complete Compatibility

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

Frequently Asked Questions

Why is my favicon not showing up in Google Search results?

Googlebot-Image crawls favicons independently on a separate schedule. Ensure your favicon URL is not blocked in robots.txt, returns a 200 OK status, and is a multiple of 48px square (e.g. 48x48, 96x96, 144x144).

Can I use SVG favicons in all browsers?

All modern evergreen browsers (Chrome, Firefox, Safari 15+, Edge) support SVG favicons. Older browsers will automatically fall back to the declared favicon.ico.
