JPEG 2000 codestream (also known as J2K, J2C, or JPEG 2000 Part 1, Core Coding System) is the wavelet-based compressed image format defined in Part 1 of the JPEG 2000 standard. It may appear in a file by itself, or embedded in JP2 or another file format.

Contents

Format

A JPEG 2000 codestream uses a variant of JPEG format, with the same system of markers and segments. (Note that the container formats used by JP2 and other JPEG 2000 file formats are completely different.)

Identifiers

There is no official filename extension, but .j2k and .j2c are commonly used.
