More about the Favicon Preview
An icon that looks crisp and detailed at full size can turn into an unrecognizable smudge once shrunk down to the sixteen pixels an actual browser tab uses, and a color scheme that reads clearly against a light background can disappear entirely against a dark one, neither of which is obvious just looking at the original full-size artwork. This tool previews how a favicon actually looks at different sizes and against various backgrounds, showing exactly what survives the shrink down to a real browser tab rather than just the original artwork at full size. Useful for checking whether a newly designed icon's fine details actually survive being shrunk to 16 pixels, seeing how an icon looks against both a light and a dark browser tab background before committing to it, or comparing a few icon design candidates side by side at their actual deployed size.
