Favicon checker
Favicon checker finds an icon candidate in a webpage response. Review the reported asset URL and confirm that it displays correctly in your browser tab.
What is Favicon checker?
Favicon checker inspects link declarations in a webpage to identify an icon candidate. It helps you review the URL a page publishes for a small identifying image, such as a browser tab icon. Use it after changing brand assets or updating a theme's icon settings.
How to use this tool
Submit the page URL and review the reported icon address. Open the address separately when you need to confirm that the asset exists and looks correct. Also check the original page in a browser, since the image chosen for a tab can depend on available declarations and browser behavior.
Understanding the results
The checker resolves relative asset paths against the submitted page URL. Its detection is broad and can match an alternate-link declaration, so a returned address is a candidate that needs confirmation. It does not verify image dimensions, formats, caching, or every icon choice a browser may make. A missing result also does not rule out a conventionally located favicon that lacks an explicit matching link tag.
Frequently asked questions
Does finding a URL prove the icon works?
No. Confirm that the URL returns the intended image and that the browser displays it. A stale browser cache can delay a recently changed icon.
Why is a non-image URL shown?
The matching logic can include alternate link declarations. Inspect the page's actual icon elements and supported theme settings before treating the candidate as the favicon.
