Google Upgrades WebP To Challenge PNG Image Format

New submitter more writes with news that Google has added to its WebP image format the ability to losslessly compress images, and to do so with a substantial reduction in file size compared to the PNG format. Quoting: "Our main focus for lossless mode has been in compression density and simplicity in decoding. On average, we get a 45% reduction in size when starting with PNGs found on the web, and a 28% reduction in size compared to PNGs that are re-compressed with pngcrush and pngout. Smaller images on the page mean faster page loads."
