A rough contrast and detail check for how your icon holds up once it's shrunk down to 16 pixels.
A favicon is one of the smallest assets on your website, and one of the easiest to get wrong. It's also one of the few brand elements that shows up outside your site entirely — in a browser's tab bar, in bookmarks, in Google's mobile search results, and on a phone's home screen after someone saves your page. When it's missing, browsers fall back to a plain gray globe, and that gap is more noticeable than most site owners expect.
The tricky part is that a favicon which looks fine in one place can quietly fail in another. An icon designed on a white background can vanish in a dark-mode tab bar. A logo with fine detail can turn into a smudge at 16 pixels. A site can have a perfectly good favicon.ico and still not show up in Google search, because Google checks a separate set of size and crawlability rules. This tool checks all of those places at once, so you catch the gap before a visitor does.
