Favicon Checker

About this tool

Favicon Checker audits a public URL or pasted HTML for favicon links, apple‑touch icons, PWA manifest references, light/dark adaptive icons, and related tile tags so you can see what browsers will request.

Best for: Debugging missing or cached favicons and confirming light/dark or Apple touch icon markup after a deploy.

How to use it

1. Enter a public site URL, or paste the page HTML if the live fetch fails.
2. Run the audit and review missing tags, manifests, and tile metadata.
3. Fix your HTML or regenerate assets with Favicon Generator.
4. Re‑scan after deploy; remember browsers may still cache old icons.

Common problems and tips

• Scan fails with a network or CORS error. Paste the page HTML instead, or try again later. Some sites block automated fetches and proxies.
• Icons show as missing but the site looks fine. Tags may be injected by JavaScript after load, or blocked redirects may hide files. View page source and network requests to confirm.
• Checker warns about light / dark favicons. Add dual <link rel="icon" media="(prefers-color-scheme: …)"> tags or an SVG favicon with prefers-color-scheme styles. Favicon Generator exports these automatically.
