A favicon or site icon is displayed in the browser tab and address bar. To add a favicon to your site, navigate to AppearanceCustomizeSite Identity and click the Select Image button. If your favicon has already been uploaded to your Media Library, navigate to it and select it. Alternatively, click the Upload Files tab and drag your favicon from your desktop into the modal window. The suggested favicon size is 512 x 512px. Once selected you’ll have the opportunity to crop your image should you need to do so. Once done, click the Save and Publish button at the top left of the Customizer window.
