Detailed explanation-1: -Lossless compression refers to compression in which the image is reduced without any quality loss. Usually this is done by removing unnecessary metadata from JPEG and PNG files. RAW, BMP, GIF, and PNG are all lossless image formats.

Detailed explanation-2: -Lossless compression uses an algorithm to shrink the image without losing any important data. Essentially, it rewrites the file to make it more efficient-resulting in a smaller storage or transfer size. One way the algorithm does this is by replacing non-essential information and storing them in an index file.

Detailed explanation-3: -Lossy is the opposite of lossless. A certain amount of data is discarded; how much is usually dependent upon a quality or bit rate setting of the codec. This makes the file (or stream) much smaller that lossless compression, but reduces the quality.
