Convert MNG to G3

The MNG (Multiple-image Network Graphics) file extension is a specialized format for animated images, originating from the creators of the PNG format. Developed in 1999, MNG supports features like image sequences, transparency, and JPEG data embedding, making it useful for complex animations and graphics interchange. Primarily utilized in web applications and multimedia presentations, it offers efficient compression and high-quality visual representation, catering to the needs of graphics-intensive environments.

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.
