Convert G4 to BRF

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 Braille Ready Format (BRF) is a digital text file format used to store braille transcriptions. Developed by the National Federation of the Blind and the American Printing House for the Blind, BRF files represent braille pages in ASCII text, making them readable by braille displays and embossers. This format supports both contracted and uncontracted braille, facilitating accessibility for visually impaired users. BRF files are essential for converting printed text into a format usable by braille notetakers and refreshable braille displays.
