Convert MRW to G4

The MRW file extension, short for Minolta Raw Image, is a raw photo file format developed by Minolta for their Dimage digital cameras. It stores uncompressed, unprocessed image data directly from the camera's CCD sensor, allowing photographers extensive post-processing control over elements like exposure and color balance. After Sony acquired Minolta, the MRW format was gradually replaced by Sony's ARW format, but MRW files remain in use, especially with legacy Minolta cameras. These files are compatible with various photo editing tools, ensuring continued accessibility for high-fidelity image editing.

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.
