+ (description
+ "WebP is a new image format that provides lossless and lossy compression
+for images. 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.")
