The J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.
The G4 file extension is linked to the CCITT Group 4 Fax Image format, recognized by the International Telecommunication Union (ITU) for its ability to compress monochrome images without data loss. This format is integral to fax technology, employing a two-dimensional coding system that identifies image patterns, resulting in high compression ratios and minimized file sizes, key for efficient document transmission.
