AVIF, or AV1 Image File Format, is a modern image format derived from the AV1 video codec developed by the Alliance for Open Media. It is designed to deliver high-quality images with superior compression efficiency compared to traditional formats like JPEG and PNG. This format supports advanced features such as HDR (High Dynamic Range), WCG (Wide Color Gamut), 10-bit color depth, and alpha transparency, making it ideal for web developers and digital content creators seeking to optimize performance and visual fidelity. Introduced in 2018, AVIF has rapidly gained adoption due to its open-source nature and effectiveness in reducing file sizes without compromising quality.
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.
