Transcoding JPG and PNG images in place allows a reduction in image data size by removing unneeded metadata, applying improved compression methods when possible, and lowering image size while maintaining perceptual quality using out SmartVision technology. As a result, the overall data transfer per image is smaller, sometimes very much so. JPG and PNG images can also be transcoded to WebP and JPEG XR files, which offers even better data size reduction in Google Chrome (WebP) or Microsoft Internet Explorer 10 and above (JPEG XR).
