- A process that reduces the storage space needed for an image file. If a digital image that has undergone lossy compression is decompressed, it will differ from the image before it was compressed (though this difference may be difficult for the human eye to detect). The most effective lossy compression algorithms work by discarding information that is not easily perceptible to the human eye. Also see lossless compression.
