Was ist eine J2K-Datei?
A J2K file is a compressed bitmap image saved in the JPEG 2000 format. It supports 16-bit color and alpha transparency and may incorporate lossy or lossless compression. J2K files typically store digital photos.

The Joint Photographic Experts Group (JPEG) committee created the JPEG 2000 format in 2000 to replace the JPEG format. However, few applications and platforms adopted the format, and the JPEG format is still overwhelmingly favored.
There are several differences between J2K files and JPG files. For example, J2K files use wavelet compression instead of the Discrete Cosine Transform (DCT) compression used by standard .JPEG images. Also, J2K files store metadata that describes the image in the XML standard instead of the Exchangeable Image File Format (EXIF).
HINWEIS: JPEG 2000 images may be saved with file extensions other than .j2k. Other common extensions include .jp2 (.JP2 files) and .jpx (.JPX files).
