Summary

This Recommendation | International Standard defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone grey-scale, palletized color, or continuous-tone colour digital still images.

This Recommendation | International Standard:

specifies decoding processes for converting compressed image data to reconstructed image data;

specifies a codestream syntax containing information for interpreting the compressed image data;

specifies a file format;

provides guidance on encoding processes for converting source image data to compressed image data;

provides guidance on how to implement these processes in practice.
