Why Use WebP on Your Website
Image weight is one of the biggest factors in page load time, and load time affects Core Web Vitals and search rankings. WebP keeps transparency like PNG while producing much smaller files, so it is a direct replacement for PNG graphics on the web.
All modern browsers, including Chrome, Firefox, Edge and Safari, display WebP. If you also need a fallback for very old software, keep the original PNG alongside.
