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. WebLossless image compression. Images are all around us, from application icons to animated GIFs to photos. Image files can take up a lot of space, so computers employ a range of algorithms to compress image files. For the simplest of images, computers can use a compression algorithm called run-length encoding (RLE).

Video and audio compression works very differently. Unlike with text where you can have lossless compression, and no data is lost, with images we have what’s called “Lossy Compression” where you do lose some data.
