Convert PICON to G3

The PICON file extension, short for Personal Icon, is primarily used for small personal icons. These icons are commonly employed in digital satellite receivers to identify various channels and on websites to add small icons to the web address bar. The PICON format, classified as a raster image file, supports multiple operating systems, including Windows, macOS, and Linux. Its history traces back to its use in Dreambox satellite receivers, where it enhanced user interface customization.

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.
