What Is WebP Format

WebP is a modern image format developed by Google that provides superior compression for images on the web. WebP images are 26% smaller than PNG at equivalent quality, and 25-34% smaller than JPG at the same quality level.

WebP supports both lossy and lossless compression, as well as transparency (alpha channel). This makes it an excellent replacement for both PNG and JPG formats.
