.webpファイルとは？

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. WebP images are typically 25-34% smaller than equivalent JPEG images and 26% smaller than PNG images while maintaining comparable visual quality. WebP also supports transparency (like PNG) and animation (like GIF), making it a versatile replacement for multiple older formats. All major browsers now support WebP.
