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 EXR file extension stands for OpenEXR, a high dynamic range (HDR) image file format developed by Industrial Light & Magic (ILM) in 1999 for visual effects and film production. OpenEXR is widely used for its ability to store multi-channel, floating-point images, supporting complex visual effects workflows with superior image quality and precision. Its features include lossless and lossy compression, arbitrary image channels, and a flexible data structure, making it an essential tool in professional digital imaging and animation industries.
