A favicon is the small icon shown in the title or tab bar of a web page and on website bookmarks. You can change your page's favicon to match your brand or identity.
In the Appearance section of the Page Editor select the Custom option under Favicon to upload your own image.
To ensure the icon appears high resolution across all devices, it is recommend to use an image at least 64 x 64 pixels in size.
This feature is only available for the Professional Plan.
