Favicon Checker

Paste domains or URLs — we’ll detect favicon tags, verify /favicon.ico, and flag broken icons or wrong content types.

Paste up to 100 domains/URLs (one per line)
Tip: A good setup includes at least one rel="icon" and a working /favicon.ico. Broken icon URLs can ruin SERP and tab icons.

“Odd content-type” usually means the icon URL returns HTML instead of an image.

Quick interpretation

Favicons are used by browsers, bookmarks, and sometimes search platforms. A broken icon link is a small issue that looks unprofessional.

Favicon Checker: verify icon tags and /favicon.ico

A favicon is the small icon shown in browser tabs, bookmarks, and shortcuts. Many sites provide multiple icon formats (PNG, ICO, SVG, Apple touch icons) for better compatibility. This tool scans favicon signals and checks that icon URLs actually load.

What this tool checks

  • HTML icon tags: rel="icon", shortcut icon, apple-touch-icon, mask-icon
  • Manifest: rel="manifest" (PWA icons)
  • Microsoft tile image: msapplication-TileImage
  • Default icon: /favicon.ico availability
  • Sanity checks: HTTP status, content-type, size, and best-effort dimensions

Common problems

  • Icon URL returns HTML (wrong path, blocked file, or redirect to a page).
  • Missing /favicon.ico — some clients still request it by default.
  • Links use relative paths that break after redirects or canonical host changes.

FAQ

Is /favicon.ico required?

Not strictly, but it’s a very common default request. Many browsers and bots still try /favicon.ico even if you set icons via HTML tags, so having it work is a safe baseline.

Why do I see “favicon.ico missing or not OK” as a warning?

It usually means /favicon.ico returns 404, redirects to HTML, or is blocked. Even if you have PNG icons in HTML, some clients still expect the default path.

What does “odd content-type” mean?

The icon URL responds with a content-type that doesn’t look like an image. Most often it returns HTML (a page, login screen, or error page) instead of image/png, image/x-icon, or image/svg+xml.

Why does the tool show HTTP 206 for some icons?

The checker downloads only a small byte range to be fast. Servers may respond with 206 Partial Content for range requests — that’s normal and not an error.

Why are icon dimensions shown as “—”?

Dimensions are best-effort. Some formats (especially SVG) or server responses make it impossible to detect size reliably from a small snippet, so the tool may leave it blank.

Does having a valid favicon guarantee it will appear in Google results?

No. Search platforms may cache, ignore, or replace favicons. This tool only checks your technical setup: icon tags, URLs, and server responses.

What icon setup is considered “good”?

A typical clean setup includes at least one working rel="icon" (PNG/SVG), a working /favicon.ico, and optionally an apple-touch-icon for iOS.

Why can icons break after moving to HTTPS or changing www/non-www?

Relative icon paths and redirects can break after canonical changes. If the HTML references /favicon-32x32.png but the final URL is a different host/path, some clients may fail. Using absolute URLs or validating redirects helps.
