JPEG, short for Joint Photographic Experts Group, is a widely-used image file format for compressing digital photographs. Established in 1992 by the Joint Photographic Experts Group, it revolutionized digital imagery by providing efficient, lossy compression that maintains significant image quality. Primarily used in digital cameras, web graphics, and image sharing, JPEG files support full-color imaging with 24-bit depth, enabling detailed and high-quality photographs in relatively small file sizes.
The G4 file extension, standing for CCITT Group 4 Fax Image, is a specialized format used primarily for storing black-and-white facsimile (fax) images. Its origins trace back to the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as the ITU-T, which developed the Group 4 standard in the 1980s to improve fax transmission efficiency over digital networks. This format employs a high compression ratio to reduce file size while maintaining image quality, making it ideal for archiving documents and transmitting faxes in professional and business environments.
