Hugo File / Image Optimization

Is there a Go package or configuration that can make Hugo implement compression on images? I haven’t been able to install or rest Hugo yet as I’ve just been reading documentation on it today and didn’t see this but it would complement minification and combining of files since many images can be decreased 59-80% and even converted to other file types like avg. If it can’t be apart of Go are there any best practices within Go or only with tools like NPM/Grunt?
