Why Your Favicon Matters

Favicons are small, but they have a big impact. They help users identify your site in tabs, bookmarks, and history. In addition, a clear icon improves trust and makes your brand look more professional.

Common favicon issues
  • Only one icon size (looks blurry on high-DPI screens)
  • Missing apple-touch-icon (iOS shows a generic icon)
  • Missing /favicon.ico (legacy compatibility problems)
  • Icons served over HTTP on an HTTPS site (mixed content blocking)
  • Manifest icons missing for PWA or Android shortcuts
