Free Favicon Checker — Does Your Site Have a Valid Favicon?

This tool checks whether a website has a favicon and whether it's correctly linked in the HTML. Enter any URL and you'll see whether a valid site icon exists and is properly referenced — the little icon that appears in browser tabs, bookmarks and, increasingly, search results.

Favicons are small but they punch above their weight for branding and trust. Google shows favicons next to listings in mobile search results, so a missing or broken one means your result looks less polished and recognizable than competitors that have one. In a crowded tab bar or a long bookmarks list, a distinctive favicon is how users find you at a glance. A missing favicon also produces a stream of 404 requests as browsers automatically look for one — minor, but untidy.

Use this tool to confirm your favicon exists and is linked correctly, to catch a broken reference after a redesign, and to verify the right formats are in place for different devices (modern sites typically provide an SVG plus PNG sizes and an Apple touch icon). If it's missing or misconfigured, adding a proper favicon and link tags is a quick win that improves how your brand shows up everywhere from the browser tab to the search results page.
