Faviscan reports which of your site icons exist and which are missing
Paste a URL. Faviscan reads the page’s <head>, collects every declared icon, then requests each one and reports what came back — present with real pixel dimensions, wrong format for what it claims, or missing entirely.
What Faviscan checks
- Declared icons — every <link rel="icon">, <link rel="apple-touch-icon">, and related declaration in the
<head>, with its declared sizes, type, and color attributes. - Root fallbacks — /favicon.ico and /apple-touch-icon.png at the site root, requested by convention even when not declared. A page can declare everything correctly and still show a blank tab because the root fallback 404s.
- Real pixel dimensions — parses the actual image bytes to confirm what size the icon is, not what it claims to be. Supports ICO, PNG, JPEG, GIF, WebP, SVG, and BMP.
Per-consumer verdicts
One report tells you what each client actually uses:
How it works
Submit any URL. Faviscan follows up to 5 redirects, respecting the final destination.
The <head> is parsed for every icon declaration — any rel value that a browser or search engine might use.
Each declared icon is fetched in parallel. The bytes are examined to determine the real format and pixel dimensions, not just the Content-Type header.
Root fallbacks are checked separately. A verdict is produced for each consumer (browser tab, Google search, iOS bookmark) showing what it would actually display.
