Abstract: Image compression is process to remove the redundant information from the image so that only essential information can be stored to reduce the storage size, transmission bandwidth and transmission time. The essential information is extracted by various transforms techniques such that it can be reconstructed without losing quality and information of the image. The development of transmission and digital imaging has junction rectifier to high amount of knowledge needed to represent fashionable im-agery. this needs giant space for storage, and durable for transmission over Computer networks, and these are comparatively high-ticket. These factors prove the necessity for pictures compression. compression addresses the problem of reducing the quantity of house needed to represent a digital image yielding a compact illustration of a picture, and thereby reducing the image storage/transmission time necessities. The key plan here is to get rid of redundancy data bestowed among a picture to scale back its size while not moving the essential information of it.
