Favicon Checker
Favicon Checker — paste a URL and get the answer in seconds.
A missing favicon is one of those faults nobody notices until a page is bookmarked or pinned. This checks every icon a site declares, plus the implicit /favicon.ico fallback, reports whether each one really loads, and points out the sizes that are missing for iOS and Android.
Frequently Asked Questions
How do I use the favicon checker?
Paste the URL into the box and press the button. The check runs on our server — not in your browser — because browsers are not allowed to read another site’s response, and the result appears within a few seconds.
Which favicon sizes do I actually need?
A 32px icon for browser tabs, a 180px apple-touch-icon for iOS home screens, and 192px plus 512px referenced from a web manifest for Android and PWA installs. The classic /favicon.ico is still worth keeping as a fallback for older browsers and feed readers.
Why does this one need a server when your other tools do not?
The browser’s same-origin policy stops JavaScript reading a response from another website, and a browser has no access at all to a TLS certificate chain. Almost every tool on this site runs entirely on your device; these few genuinely cannot, so they run on ours instead.
Do you store the URLs I check?
No. The request is made, the answer is returned to you, and nothing about it is kept.
Can I check a site that is not mine?
Yes — everything here reads only what the site already serves publicly to any visitor. Nothing is scanned, probed or attacked; it is the same information your own browser fetches when it loads the page.
