CCITT Group 4 Fax Image (.g4)

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.

JPEG 2000 Code Stream Syntax (.j2k)

The J2K file extension stands for JPEG 2000 Code Stream Syntax, a part of the JPEG 2000 standard developed by the Joint Photographic Experts Group (JPEG). Introduced in 2000, JPEG 2000 offers superior image compression and quality compared to the original JPEG format. The J2K codestream is highly flexible, supporting both lossy and lossless compression, and allows for scalable decoding, which means images can be efficiently accessed at various resolutions and quality levels. This makes J2K ideal for applications requiring high-quality image storage and transmission, such as medical imaging, digital cinema, and satellite imagery.
