Image files constitute a majority of total web traffic.[17]
Unlike text-based web file formats, binary image files do not benefit from
built-in webserver-based HTTP gzip compression.
imgmin offers an automated means for enforcing image quality as a
standalone tool and as a webserver module.
imgmin determines the optimal balance of image quality and filesize, often
greatly reducing image size while retaining quality for casual use, which
translates into more efficient use of storage and network bandwidth, which
saves money and improves user experience.
