The DjVu file extension, developed by AT&T Labs in 1996, stands for "Digital Journal Viewer". It is designed to store scanned documents and combine text, line drawings, and images with high compression efficiency. DjVu files are widely used for digitizing books, magazines, and historical documents due to their ability to produce smaller file sizes compared to PDF, JPEG, and TIFF formats. This format employs advanced technologies like image layer separation, progressive loading, and arithmetic coding, making it ideal for web distribution and archival purposes.
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.
