Convert K25 to G4

The K25 file extension stands for Kodak DC25 Digital Camera Raw Image. It is a proprietary format used by the Kodak DC25 digital camera, introduced in the mid-1990s. K25 files store unprocessed image data directly from the camera's sensor, preserving high image quality and allowing extensive post-processing. This format was pivotal in early digital photography, enabling users to manipulate images without significant quality loss.

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.
