Favicon checker

Discovers every favicon declaration on a page - icon, apple-touch-icon, mask-icon, manifest icons, and the root /favicon.ico fallback.

1 · Input


What is checked

Every <link rel="icon">-family tag (icon, shortcut icon, apple-touch-icon, apple-touch-icon-precomposed, mask-icon), whether a web app manifest with its own icons is linked, the root /favicon.ico fallback, duplicate declarations, and the common declared sizes (16x16, 32x32, 180x180).

Safe previews

Icon previews are rendered as plain <img> elements pointing at the discovered URL - an SVG icon is never injected into the page as live markup, only ever loaded as an image.
