Convert PCD to G3

The PCD (Photo CD) file extension, developed by Kodak, is used for storing digital images on a Photo CD. This format was introduced in the early 1990s to digitize and archive physical photographs. PCD files contain high-resolution images scanned from film, typically at resolutions of 3072 x 2048 pixels or higher. These files are utilized for preserving, viewing, and editing images using compatible software. The PCD format supports 24-bit color and includes multiple resolutions within a single file, facilitating versatile image processing and archival purposes.

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.
