The CRW file extension stands for Canon Raw CIFF Image Format, a raw image file format used by Canon digital cameras. Developed to store uncompressed and unprocessed images, CRW files offer high-quality image data that can be edited with Canon's software or third-party editors like Adobe Photoshop. Introduced by Canon, this format has been largely superseded by newer formats like CR2 and CR3 but remains significant in the history of digital photography for its role in preserving image integrity.
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.
