Files with JPX extension belong to JPEG 2000.  These files are image files created using the specifications and format of JPEG released in 2000.  JPEG or Joint Photographic Experts Group is a standard image file that is widely accepted around the world.  Many image files and pictures that are saved on people’s computers are saved under the JPEG format specifications.  Back in 2000, some JPEG image files are saved with the JPX extension. These files are considered update files to the previously released format of 1992.  Along with files with JP2 extension, JPX files are image files that conform to international standards.

JPX files are created using a program called JBuilder. This application runs under the Java platform and is able to create JPEG 2000 files or files with JPX extension.  The wide acceptance of JPX files is its main feature of image compression.  Under the JPEG 2000 specifications, image files are saved and rendered using a compression technique.  This technique enables the files to be saved with much fewer megabytes compared to other image saving formats.  Fewer megabytes simply translate to less storage or disk space requirements for files that are saved with the JPX extension.  Aside from the standard image content of JPX files, they may also carry or store other details relating to them.  These details may include metadata, color space, and resolution details.

Compared to the previous image format of 1992, JPEG 2000 files that have the JPX extension feature a much-improved compression technology. This is due to enhancements made on the image encoding under JPEG standards.  JPX image files also have the progressive transmission feature in terms of image resolution and the pixel density.  In the case of transferring image files that have the JPX extension, the image may be partially displayed with few pixels as the data stream is ongoing.  With all image components received, the partial display of an image will then be completed resulting to a more vivid photo with the specifications of the original JPX file.  JPX files may also be saved with either a lossy or lossless compression technique.
