Convert CR2 to G3

The CR2 (Canon Raw 2) file extension, developed by Canon Inc., is a digital image format used for capturing high-quality raw data from a camera's sensor. Introduced in 2004 with the Canon EOS-1D Mark II, the CR2 format preserves all the original details and metadata, allowing for extensive post-processing flexibility. It is preferred by professional photographers and IT specialists in image processing for its ability to retain maximum image information, facilitating enhanced editing and manipulation capabilities. The CR2 files are integral to workflows that require precision and detail, making them indispensable in fields like digital photography, imaging technology, and computer graphics.

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.
