What is a Favicon?
Learn the basics
What does the favicon checker test?
The favicon checker analyzes a website's HTML and server responses to preview the icons that browsers and mobile devices can reach. Use it as a favicon tester when you want to confirm that a live site has the right favicon files installed. It checks for:
- favicon.ico — The classic favicon file at the website's root directory
- PNG favicons — Modern <link rel="icon"> tags with PNG images in standard sizes (16x16, 32x32)
- Apple Touch Icon — The 180x180 icon used when iOS users add your site to their home screen
- Web App Manifest — The manifest file containing 192x192 and 512x512 icons for Android and PWA support
- SVG favicon — Optional scalable vector icon for modern browsers, shown separately from the package score
Why check your favicon?
A properly configured favicon helps with brand recognition, improves your appearance in browser tabs and bookmarks, and ensures your site looks professional in Google search results. Missing or broken favicons can make your site appear untrustworthy to visitors.

Why is my favicon not showing up?

What favicon files do I need?
At minimum, you need a favicon.ico (16x16, 32x32, 48x48), an apple-touch-icon.png (180x180), and android-chrome icons (192x192 and 512x512) in a web manifest. See our complete favicon sizes guide for details.
