Convert J2C to PICON

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.

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.
