How to use Favicon Checker online, free

Check which favicon(s) a website has declared - the small icon shown in browser tabs, bookmarks, and search results - and shows how they actually render across different contexts. Useful for verifying your favicon setup is complete and displaying correctly everywhere it should.

SEO and webmaster checks are only useful if they match what Googlebot or a browser would see. Guessing from the HTML source alone is how people ship broken tags.

Favicon Checker is a good fit when auditing favicon setup after website redesign.

Why this exists

Favicon Checker is built around a few practical wins, not a long feature list:

• Detects incomplete favicon setups before users notice broken branding.
• Improves tab, bookmark, and share-surface brand recognition.
• Helps validate cross-device icon coverage quickly.
• Useful for post-launch QA and rebrand verification.

Walkthrough

1. Enter website URL. Fetch declared favicon links and icon manifest references from the page head.
2. Inspect icon variants. Review `.ico` and PNG sizes used for tabs, bookmarks, and devices.
3. Check render quality. Verify clarity at small sizes where blurry icons usually fail.
4. Fix and redeploy icon set. Regenerate missing sizes and update head tags as needed.

Jobs it is built for

• Auditing favicon setup after website redesign.
• Debugging missing icons on iOS/Android homescreens.
• Checking brand consistency across browser contexts.
• Verifying client deliverables include full icon pack.

Worth knowing before you start

• Provide both `.ico` and multiple PNG sizes for compatibility.
• Use simplified icon marks for tiny 16x16 rendering.
• Clear browser cache after favicon updates during testing.
• Include Apple touch icon and manifest references where needed.

What not to expect

• Uploading one large logo and relying on browser downscaling only.
• Forgetting root `favicon.ico` fallback path.
• Using detailed text-based logos that blur at small sizes.
• Changing icon files without updating cache-busting strategy.

Privacy, in one paragraph

Favicon Checker needs the ToolBox API for work a browser cannot do. What you submit is processed, then discarded. It is not kept as a library of your files.

If this is one step in a longer job, these usually come after it:

• Favicon Generator - Turn any image, text, or emoji into a complete favicon package
• Meta Tag Analyzer - Analyze meta tags of any webpage by URL or pasted HTML

Short answers

Why might my favicon not show up in some places?

Different platforms (browser tabs, mobile home screen icons, search results) often expect different favicon sizes/formats - missing one of the expected variants can mean the icon fails to appear in that specific context even if your main favicon works fine.

What favicon formats/sizes should a site typically have?

A common baseline includes a standard .ico file plus various PNG sizes for different devices, and often an Apple touch icon for iOS home screen bookmarks - covering the range of places a favicon might be displayed.

Can I check any website's favicon setup, not just my own?

Yes - enter any public URL to see what favicons that site declares and how they're configured.
