Favicon Validator
Check your favicon against Google's requirements and browser standards.
You spent weeks on your logo. Google crops it to 16 pixels square and sticks it next to your URL in every search result. It should work at 16 pixels. This checks if it does — and whether Google will even show it.
We'll probe common favicon paths at your domain using image loading — no fetch, no CORS issues. For full link-tag analysis, use Paste HTML mode.
