Convert G4 to JIF

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.

The JIF (Joint Photographic Experts Group Interchange Format) is a standard for compressing and encoding digital images. Initially introduced in 1992 by the Joint Photographic Experts Group, JIF became widely adopted due to its efficient lossy compression method, which significantly reduces file size without a substantial loss in image quality. Primarily used for web graphics and digital photography, JIF has influenced the development of other formats like JPEG and its various subtypes, ensuring high compatibility across different platforms and devices.
