What is a j2k file?

J2K is a file extension used for JPEG-2000 standard image files. The Joint Photographers Expert Group created JPEG-2000 standard as an improvement on the JPEG baseline digital image standard. One of the advantages of J2K image files over standard JPEGJPG files is the ability to truncate the post-compression code stream. Having an adjustable code stream provides flexible results, such as scalable compression and improved application performance. J2K files feature can be compressed by both lossless and lossy methods. Due to the greater flexibility in code stream manipulation, the standard requires more complex and higher functioning encoder and decoders. Since web browsers do not commonly support J2K, it is not prevalent on the web.
