- The quick facts

What are JP2 files and how to open them

Are you having problems opening a JP2 file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a JP2 file?

A .JP2 file is a JPEG 2000 Image file.

Files that contain the .jp2 file extension normally store compressed bitmap images. The JPEG2000 Core Coding System 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 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.
