Convert ICON to G3

An ICON file, an abbreviation for Icon Image File, is primarily used in Microsoft Windows operating systems to represent graphical icons. These files are essential for visually identifying applications, files, and folders, enhancing user experience through graphical representation. ICON files support multiple sizes and color depths, ensuring compatibility and visual clarity across different display settings. Introduced in the early versions of Windows, ICON files have evolved to accommodate higher resolutions and color variations, aligning with advancements in display technology. Their primary function is to provide a quick, intuitive visual reference for software and system elements.

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.
