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.
