Favicon Checker

Enter a page URL: the tool reads the icons declared in the HTML, tests every file and checks the /favicon.ico fallback.

Page URL

Privacy and cost

This tool requests the public URL you enter from our servers. It is free, rate-limited to prevent abuse, and we do not store the URL or the page content.

How it works

Enter the URL of the page whose icon you want to check.
The tool extracts rel=icon, apple-touch-icon and mask-icon links and the manifest link.
Each icon is tested (HTTP status, Content-Type, size) along with /favicon.ico, and the problems are listed.

Example

A page that declares <link rel="icon" href="/favicon.ico"> while the server returns its HTML error page with a 200 status is flagged: the icon answers "reachable (HTTP 200)" but its Content-Type is HTML, so it is not an image.

What the result means

The favicon is the icon shown in the browser tab, bookmarks and, for Google, mobile search results. It must be an image reachable at a stable, crawlable URL. With no rel=icon link, browsers request /favicon.ico at the site root. Google recommends a size that is a multiple of 48 px.

Common problems this tool helps with

A declared icon that answers 404, 403 or an HTML page.
No rel=icon link, so only the /favicon.ico fallback can work.
A missing or wrongly sized apple-touch-icon, giving a blurry thumbnail on iOS.
An icon blocked by robots.txt or too heavy, which Google cannot use.

Frequently asked questions

What favicon size should I use?

Google asks for a square whose side is a multiple of 48 px (48×48, 96×96…), at least 8×8. Add a 180×180 px apple-touch-icon for iOS.

Does Google always show my favicon?

Not always: the icon must be crawlable, stable and follow Google's guidelines, and updates can take a while to appear.

Why does the tool use a server?

To read the headers of icon files, which a browser cannot inspect across domains. Requests go through a secured access that refuses private addresses.
