J2K to BMP Conversion: FAQ

What are J2K files?

J2K represents an upgrade of the JPEG format, including more features, such as supporting transparency and alpha channel, or lossless compression. J2K is part of a larger pack of improved JPEG extensions, known as JPEG2000, together with formats such as J2C, JPX, JPM or JP2. Most of these formats are compatible with mainstream image viewers, but do not enjoy the popularity of JPEG.
