JP2 files, normally with the .jp2 extension, store bitmap images. You can also use them to store biometrics, cinema and internet graphics, medical pictures, or digitized scans. You can only create this file format using a standard JPEG 2000 core coding application, which uses a discrete wavelength transform as its compression algorithm.

This technique allows these files to support lossy and lossless image compression. JP2 files mainly contain graphics but may also have the image metadata, bit depth, and resolution.
