I created a site using Gatsby and I wanted to change the favicon.

Open the gatsby-config.js file and change the plugins.gatsby-plugin-sharp.options.icon property from src/images/gatsby-icon.png to the one you want.

For example I put my new favicon image in src/images/logo-small.svg and I changed that configuration property to point to it.

I ran gatsby develop and I could immediately see Gatsby updated all the favicon images, in different sizes:
