Gzip compression can speed up your WordPress website. When someone visits your site, their browser requests files like HTML, CSS, and JavaScript. Gzip compresses these files on the server before sending them to the visitor’s browser. Their browser then decompresses them and displays the site. This process happens quickly and automatically. With the usage of Gzip compression you also use lesser bandwidth and improve your Core Web Vitals score.
