Convert DCR to G4

The DCR (Digital Camera Raw) file extension is used by Kodak digital cameras to store uncompressed, lossless image data exactly as captured by the camera's sensor. This format retains more detail and allows for greater post-processing flexibility compared to compressed formats like JPEG. DCR files contain metadata such as camera settings and image dimensions. Historically, Kodak introduced this format to provide photographers with high-quality images for editing and archival purposes.

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.
