.JPX File

The jpx file extension is associated with the JPEG 2000 file format, an image compression format based on the wavelet technology. The format itself is defined by several standards (parts), from the basic coding system, to support of other various aspects.

JPEG 2000 is more sophisticated image format than JPEG. It offers superior compression performance and compared to JPEG fully supports transparency and alpha planes.

The jpx files are JPEG 2000 images that also contain the second standard (PART 2) of the file format. PART2 is proprietary and is also as the ISO/IEC 15444-2 standard.

jpx file extension is more common for Mac platform. For Windows, the preferred suffix is the jpf file extension.

Viewers or editors that are able to open the .jpx files also have the options to save or export them another image file format.
