32x32 Icon

Checks that an icon is defined in the HTML for the 32x32 size.

The favicon.ico file is a legacy format that you should include, but for modern web browsers it is better to provide an optimized PNG image. You can do this by including a <link> tag in the <head> of the webpage. The website should define several different sizes for different purposes. One of those sizes is the 32x32 pixel size. The following code is our recommendation.

<link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">

This test will check for the presence of a <link> tag with the appropriate size and then download the image to make sure it is the proper size and format.
