WebP is a raster image format developed by Google intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression, animation, and alpha transparency.
WebP files are typically smaller than JPEG or PNG files for comparable image quality. This is because WebP uses a more efficient compression algorithm. WebP files are also smaller than GIF files, even when they are animated.
WebP is supported by most modern web browsers, including Chrome, Firefox, Edge, and Opera. It is also supported by some image editing software, such as GIMP and Photoshop.
Here are some of the benefits of using WebP format:
- Smaller file sizes: WebP files can be up to 26% smaller than PNG files and 25-34% smaller than JPEG files at an equivalent SSIM quality index.
- Better image quality: WebP files can retain more image detail than PNG files at the same file size.
- Support for animation: WebP files can be animated like GIF files.
- Support for alpha transparency: WebP files can support alpha transparency, which is useful for images with semi-transparent elements.
Here are some of the drawbacks of using WebP format:
- Not as widely supported as JPEG or PNG: Not all web browsers and image editing software support WebP yet.
- Not as well-known as JPEG or PNG: WebP is not as well-known as JPEG or PNG, so there may be some compatibility issues.
