Favicon URL builder

build favicon URLs for any domain · 4 services, side-by-side preview

Construct the standard favicon URL patterns for a domain — the site's own /favicon.ico, Google's S2 service, DuckDuckGo's icons API, Icon Horse — with side-by-side preview.

How to use

Paste a domain or full URL.
The tool emits four URL patterns:
- https://example.com/favicon.ico
- https://www.google.com/s2/favicons?domain=example.com&sz=64
- https://icons.duckduckgo.com/ip3/example.com.ico
- https://icon.horse/icon/example.com
A preview row uses <img> tags to actually render each one — the browser handles the request, so it works without us hitting any API.
Copy any URL or Copy all as HTML for a fallback chain.

Which service for what

Own /favicon.ico — the only source you fully control. Use this for your own product.
Google S2 — high coverage, configurable size, fast. Good default for displaying third-party domains in a UI.
DuckDuckGo — privacy-friendly, no tracking. Sometimes misses obscure domains.
Icon Horse — higher quality (does best-effort search if /favicon.ico isn't found), but rate-limited on the free tier.

FAQ

Does this tool fetch the favicons?

The browser does, when it renders the preview row's <img> tags. That means each service sees your IP and the domain you're looking up. The URL builder itself runs locally.

Why use a third-party service vs. the site's own favicon?

Reliability and uniformity. Some sites don't host /favicon.ico directly; they use Link headers, manifest.json icons, or just nothing. Google S2 / DDG / Icon Horse abstract over all of that.

Can I get different sizes?

Google S2 supports sz=16, 32, 64, 128, 256. The others return a single fixed size.

Is this safe to use in production?

For external services, you're trusting them to stay up. Self-host the icon (download it once, cache it) if reliability matters.
