Convert ICON to J2C

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 J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.
