Favicon Checker
Check which icons a page declares and which platforms have nothing to show.
About this tool
Lists every icon a page declares — favicon, Apple touch icon, web app manifest — and says which platforms are left without one.
This is not cosmetic. Google shows a favicon next to every result on mobile, so a missing one is a visible hole in your search listing. The usual cause is a site that declares the modern icons correctly and assumes the old /favicon.ico fallback stopped mattering. It did not.
Common questions
Does a favicon affect SEO?
Not rankings. It affects the result itself — Google displays a favicon beside every mobile listing, and a missing one leaves a blank where every competitor has a logo. That is a click-through problem, not a ranking one.
What sizes do I need?
A 32x32 for browsers, a 180x180 apple-touch-icon for iOS, and 192x192 and 512x512 in a manifest for Android. Google asks for a multiple of 48 pixels and square. One well-made SVG plus a fallback .ico covers most of it.
Why does my old favicon still show?
Favicons are cached aggressively by browsers and by Google, sometimes for weeks. Changing the filename forces browsers to refetch; Google refreshes on its own schedule and there is no way to hurry it.
Do I still need /favicon.ico?
Yes, as a fallback. Some crawlers and older software request that exact path regardless of what your HTML declares, and it costs nothing to have it there.
