Files that contain the .jp2 file extension normally store compressed bitmap images. These files are most commonly created using the JPEG2000 Core Coding application.
The JPEG2000 Core Coding software uses a wavelet compression algorithm instead of the common DCT compression method that is used with standard JPEG images.
The JP2 file format can be used to store either lossy or lossless compressed JPEG images and provides the user with a better quality and smaller file size than the traditional JPG image files.
JP2 files are identical to JPX files, except they are stored with the .jp2 file suffix rather than the .jpx file extension.

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the JP2 file format or software that uses files with the JP2 suffix, please do get in touch - we would love hearing from you.
