Favicon Checker
See which site icons a page exposes to browsers and search interfaces.
Inspect favicon declarations
The tool finds icon and related rel values, resolves each href, and displays declared type and sizes beside a visual candidate.
Interpret the result
The inventory shows which page-level icons browsers and search interfaces can discover from HTML declarations.
Catch common problems
Missing declarations, broken URLs, unsuitable formats, absent size variants, or an icon that lacks contrast can produce generic or poor branding.
How to interpret favicon declarations
The tool does not download every candidate to validate bytes, dimensions, cache state, manifest icons, or how a specific platform ultimately displays it.
Common problems and next steps
