Convert PICON to JBG

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 JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
