Coverage by surface
Each row answers a different question. A browser fallback does not replace a home page declaration for Google Search.

What to check next
Icon evidence
Declared values and detected file details stay separate so a wrong size or type hint remains visible.
Files to review
What this check cannot prove
Check the home page favicon declarations
Enter a domain or any URL on the site. The checker uses the hostname's home page because Google supports one favicon per hostname. It reads icon link elements, checks the usual /favicon.ico fallback, and follows one declared web app manifest.
Each icon result keeps the declared relationship, size, type, and purpose next to the fetched file's HTTP response, byte size, format, and detected dimensions. That makes a stale declaration or wrong image response easier to spot.
Google Search favicon requirements
Google asks for a supported icon link on the home page, a stable icon URL, and a square image of at least 8 by 8 pixels. Google recommends an icon larger than 48 by 48 pixels for clearer rendering across its surfaces. The home page and icon must also be crawlable by Googlebot and Googlebot-Image.
This check can confirm the declaration, response, format, and dimensions it observes. It does not run as Googlebot or decide whether the image is visually representative of the site. Meeting the checked requirements does not guarantee that Google will show the icon. Read the current Google Search favicon documentation before changing a production site.
Browser, iOS, and web app icons are separate
Browsers can use a declared icon or the conventional /favicon.ico file. Apple touch icons are intended for iOS home screens. Manifest icons are used when a web app is installed and can declare purposes such as maskable. One file may cover several surfaces, but the declarations are still different.
The web app manifest icon reference explains how manifest sizes, types, and purposes guide browsers and operating systems.
What the checker covers
The checker reads the home page declarations, the usual favicon.ico fallback, Apple touch icons, and icons from the web app manifest. Each result shows a preview, response status, file type, dimensions, and the places where the icon can be used.
Use the findings to catch missing files, broken declarations, incorrect sizes, and gaps between browser, search, iOS, and installed app icons.
