WebCompression allows a larger number of images to be stored on a given medium and increases the amount of data that can be sent over the internet. It relies on two main strategies: redundancy reduction and irrelevancy reduction. Redundancy reduction, used during lossless encoding, searches for patterns that can be expressed more efficiently.

Web1.1.2 Lossy Compression.
