JPEG 2000 is a file format for encoding raster images created in 2000 by the Joint Photographic Experts Group to improve JPEG. It stands out to be one of the most scalable standards. Different parts of an image can be stored using diverse qualities.
JPEG 2000 supports progressive encoding, an efficient method for image encoding that displays the lower-quality recognizable version of an image during data transmission; the quality improves as more data bits arrive. It also delivers both lossy and lossless image compression which for JPEG it was only lossy. JPEG 2000 also supports transparency in images and preserves higher quality than JPEG images for the same size. On the other hand, not all the major browser supports it and it has a CPU-intensive encoding.
