The compression format it specified has since been widely used, particularly in consumer digital photography. This success is due to its technical performance, the fact that no royalties are payable, and the availability of free, efficient software (codec) from the Independent JPEG Group.
However, JPEG's limitations (in terms of lossless mathematical quality, scalability, etc.) became apparent with the need to compress images in fields...
