Convert RW2 to G3

The RW2 file extension stands for Panasonic Digital Camera Raw Image File, primarily used by Panasonic LUMIX cameras. This format captures uncompressed image data directly from the camera's sensor, ensuring high-quality images suitable for professional editing. Introduced with models like the LUMIX LX3 and LX5, RW2 files are based on the TIFF specification and are similar to other raw formats like RAW and RWL. These files can be opened and edited using various software.

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.
