As one of the most important elements on a web page, the size and quality of images directly affect the loading speed of the web page and the visual experience of users. To optimize the loading speed of web pages and enhance user experience, an image format called WebP has emerged.

WebP is an image format that supports both lossy and lossless compression. Its greatest advantage lies in its ability to significantly reduce file size while ensuring image quality. Compared with the traditional PNG format, the image file size of WebP lossless compression can be reduced by 26%. Compared with the JPEG format, the image file size of WebP lossy compression can be reduced by 25% to 34%. This means that in the same network environment, images in WebP format can load more quickly, thereby improving the loading speed of web pages.

In addition, WebP also supports transparency (alpha channel), which enables WebP to achieve richer visual effects while ensuring image quality. Moreover, WebP\'s lossy compression supports transparency, which can further reduce file size when processing images with transparency.
