Do you optimise your website favicon?

Favicons are more than just a single icon, and they require proper optimisation to display correctly on all devices.

What is a Favicon?

Favicons are most commonly used to display a custom icon on a browser tab, but they can also be used to alter the display of your website in other cases such as Android, iPhone, Windows, and Mac icons.

How to Check Your Favicon

Even if your website has a favicon, it may not be fully compliant. You can use realfavicongenerator.net to check your website.

How to Update Your Favicon

realfavicongenerator.net also has a favicon generator that you can use to generate a set of icons and meta tags from a single image.

The site will guide you through all the settings and display a preview of how your favicon will look on each device.
