Convert RW2 to G4

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 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.
