JasPer is a project to create a reference implementation of the codec specified in the JPEG-2000 Part-1 standard, (ie. ISO/IEC 15444-1). The project was started by Image Power, Inc. and the University of British Columbia. It consists of a C library and some sample applications useful for testing the codec.

The license was changed in early 2004 to an MIT License-style one, in response to requests from the open source community. It is now used as a component of many software projects, both free and proprietary, including (but not limited to) netpbm (as of release 10.12), ImageMagick and KDE (as of version 3.2). As of June 22, 2010, GEGL graphics library has supported JasPer support on its latest Git versions.
