The degree of compression is adjustable so a user can choose the trade-off between file size and image quality. WebP typically achieves an average of 39% more compression than JPEG and JPEG 2000, without loss of image quality. + +WebP is a new image format that provides lossless and lossy compression for +images on the web. WebP lossless images are 26% smaller in size compared to +PNGs. WebP lossy images are 25-34% smaller in size compared to JPEG images at +equivalent SSIM index. + +WebP supports lossless transparency (also known as alpha channel) with just 22% +additional bytes. Transparency is also supported with lossy compression and +typically provides 3x smaller file sizes compared to PNG when lossy compression +is acceptable for the red/green/blue color channels. + +Webmasters and web developers can use the WebP image format to create smaller +and richer images that can help make the web faster. |
