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.
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.
