Ways to go deeper with this site:
The right set depends on where your site needs to appear. Start with a square icon declared using <link rel='icon'>. You can also provide /favicon.ico as a conventional fallback, an apple-touch-icon for Apple home-screen bookmarks, and a web app manifest with app icons if you offer an installable web app. These files are not all mandatory for every website.
An apple-touch-icon gives Apple devices a chosen image for a website or web app saved to the Home Screen. Apple documents a 180×180 option for Retina iPhone displays, with other sizes available for different devices. This checker detects the link and its declared sizes but does not measure the image.
Google documents favicons as a search-result appearance feature, not a ranking factor. A valid favicon can make your site eligible to show a recognizable icon, but Google does not guarantee that it will display. This checker cannot measure rankings, impressions, or click-through rate.
Size requirements vary by context. Google Search currently requires a square favicon of at least 8×8 pixels and recommends one larger than 48×48. Apple documents device-specific touch-icon sizes, including 180×180. Chromium installability criteria expect 192×192 and 512×512 icons in the manifest. This checker records declared sizes but does not inspect image dimensions.
Check that the icon URL resolves, the HTML link uses rel='icon', the response is an actual supported image, and caching is not serving an older file. Relative icon URLs are valid when they resolve correctly. This tool only sends HEAD requests, so confirm the icon in a browser if the server handles HEAD differently from GET.
A web app manifest is a JSON file that describes an installed web app, including its name, icons, start URL, and display behavior. A basic content website does not need one solely to show a browser favicon. This checker confirms whether a linked manifest returns a successful HEAD response; it does not parse the manifest or test installability.
Create a square icon, publish it at a stable URL, and reference it in the page head with <link rel='icon' href='/path/icon.png'>. Add sizes and type when useful. Provide an apple-touch-icon or web app manifest only when those contexts matter, then test the live page and files in the browsers and devices you support.
The Favicon Checker fetches up to 500 KB of HTML from the submitted page and extracts supported icon-related link tags, including<link rel="icon">,<link rel="shortcut icon">,<link rel="apple-touch-icon">, and <link rel="manifest">. It then sends a HEAD request to each resolved URL and reports whether it returns a successful 2xx response. It also probes the conventional /favicon.ico fallback even when it is not declared in HTML. The result records link type, URL, declared size, response status, and an in-page preview where the resource can be rendered as an image. It does not inspect image dimensions or contents, parse the manifest, or reproduce browser selection behavior. Some servers also handle HEAD and GET differently, so confirm uncertain results in a browser.
Start with a square site icon declared using rel="icon". A root /favicon.ico can provide a conventional fallback. Add an Apple touch icon when Home Screen bookmarks matter, and add a web app manifest with app icons when you support an installable web app. Use the sizes attribute on link elements to describe raster dimensions; SVG icons can use sizes="any". The checker's score rewards coverage of these common declarations, but it is a configuration heuristic rather than a browser-compatibility or PWA-installability test.
Google Search can show a site's favicon with organic results, but appearance is not guaranteed. Google reads supported icon links from the home page, including <link rel="icon"> and requires the home page and image to be crawlable. Its current guidance requires a square icon of at least 8×8 pixels and recommends an icon larger than 48×48 for display across surfaces. Keep the favicon URL stable and use an image that clearly represents the site. This tool checks URL responses and declarations only; it cannot confirm Google's crawl access, processing, or final search-result display.
