About Favicon Checker
Free online Favicon Checker tool.
Favicon Checker confirms that your site shows the small icon people use to find you among open tabs. Enter a URL and the tool requests the usual icon locations, from the classic favicon file to the modern link declarations, then reports the sizes and formats it found such as png, svg or avif. Missing icons, mismatched declared sizes and files that fail to load are listed with the exact path to fix, and you can see a rendered preview of how the icon looks at tab size. Designers hand off assets with it, developers catch a broken path after a deploy and site owners verify the branding on every template. Favicon Checker is free, runs in your browser and keeps no reports.
