What is a J2K file?
A .J2K file is specifically a JPEG 2000 Image file.
The .j2k file extension represents a raster bitmap image file type utilized by Joint Photographic Experts Group (JPEG) 2000 files. Unlike the standard .jpeg or .jpg format, JPEG 2000 employs wavelet-based image compression instead of DCT (Discrete-Cosine-Transform) compression and stores metadata. The metadata or description information of the .j2k file is encoded in XML, distinguishing it from the EXIF data typically found in standard JPEG files.
JPEG 2000 files are saved with a .j2k extension, but they can also use either a JP2 or JPX extension. While not as common as standard JPG files, J2K files support 16-bit color, alpha transparency, and lossless compression. They can be opened on Windows using popular image viewers and editors pioneered by Adobe and Corel.
