About the Favicon Checker
The Favicon Checker reads every icon declaration from a page's HTML, probes the default /favicon.ico path, and verifies each file actually loads — with live previews, HTTP status and file size. Missing or broken icons cost you the logo in browser tabs, bookmarks and Google's mobile results. Need icons? Use the Favicon Generator.
A 32×32 PNG covers browser tabs, 180×180 apple-touch-icon covers iOS homescreens, and a 192/512px icon serves Android/PWA — plus the legacy /favicon.ico for old clients.
Google requires a crawlable icon that is a multiple of 48px, referenced on the homepage, and stable — check that it returns 200 and isn't blocked by robots.txt.
Browsers request /favicon.ico as a fallback when no link tag is found; serving one avoids 404 noise in logs even if modern tags exist.
