Frequently asked questions

Do I need every favicon size?

No. A browser tab uses one selected icon. Extra sizes matter only for the platforms you target, such as a home-screen shortcut or an installed web app. This checker does not require every size.

Must my icon be named favicon.ico?

No. An icon declared in HTML or a manifest can live at another path. /favicon.ico is only a labeled root fallback. Optional filenames are probes, not required files.

Why does the checker see HTML instead of an image?

The URL returned an HTML document, often an error page. HTTP 200 and a .ico extension do not make that body an image.

Does this confirm the icon appears in Google Search?

No. Google publishes separate favicon guidelines. Meeting them does not guarantee display and is not a ranking claim. This checker does not test Googlebot.
