OpenJPEG is an open-source library to encode and decode JPEG 2000 images. As of version 2.1 released in April 2014, it is officially conformant with the JPEG 2000 Part-1 standard.[3] It was subsequently adopted by ImageMagick instead of JasPer in 6.8.8-2[4] and approved as new reference software for this standard in July 2015.[5] OpenJPEG is a fork of libj2k, a JPEG-2000 codec library written by David Janssens during his master thesis at University of Louvain (UCLouvain) in 2001.

Unlike JasPer,[6] another open-source JPEG 2000 implementation, OpenJPEG fully respects the JPEG 2000 specification and can compress and decompress lossless 16-bit images.
