Logo is part of the header and your site identity.
Customizer
To upload your own logo, you can do it from WordPress Customizer. To access customizer, please navigate to Appearance > Customize > Site Identity > Logo in your WP Admin.
SVG Logo
We recommend using a SVG logo for best experience in all types of screens including the Retina.
By default, WordPress does not allow SVG files to be uploaded for security purposes. You need to use a plugin like Safe SVG to upload your SVG logo safely.
Dimensions
The dimensions of the logo used in our demo is 92×28 pixels.
