WebP is an innovative image file format designed for the Web. With the WebP format, image file sizes can be reduced by 25-34%, which is a significant optimization compared to traditional PNG and JPEG formats without sacrificing image quality.WebP images not only help to accelerate the loading speed of WordPress websites, but also work in tandem with WordPress caching plugins, CDNs, and other highly effective tools to further improve website performance.
