I too like webp, both for lossy and lossless images (particularly lossless), and you're right, the best I got (lossless) was 34.5kb using: cwebp -lossless -pas

I too like webp, both for lossy and lossless images (particularly lossless), and you're right, the best I got (lossless) was 34.5kb using: cwebp -lossless -pass 10 -m 6 MaxCDN-WebP.png -o image.webp Still that's not a bad compression improvement given that 'pngcrush -brute' failed to improve compression and pngout managed only to bring it down to 50.1kb
