Compressing resources using gzip or deflate can reduce the amount of data transferred over the network. This is the recommendation that usually appears after checking the site using PageSpeed Insights.
If the owner of the resource does not have sufficient skills to fix the problem, he can contact the technical support service of the resource with the request to enable gzip-compression of the site files.
