Convert MRW to G3

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 G3 file extension refers to the CCITT Group 3 Fax Image, a standardized format developed by the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as ITU-T. This format was created to efficiently compress black-and-white fax documents for transmission over telephone lines. It employs a method called Modified Huffman Coding for data compression, enabling reduced transmission time and bandwidth usage. G3 was widely adopted in the 1980s and 1990s as the primary standard for fax transmissions, ensuring compatibility across different fax machines and systems.
