Convert ICO to JBIG

The ICO file extension, standing for "Icon", is integral to Microsoft Windows for storing icons of different sizes and color depths. Its primary use is to display graphical representations of executable programs, files, and folders within the Windows operating system. The ICO format's origins trace back to the early versions of Windows, evolving over the decades to support enhanced resolutions and alpha transparency. Today, ICO files ensure visually consistent and scalable icons that maintain their appearance across various display settings, aligning with modern user interface standards.

The JBIG (Joint Bi-level Image Group) file extension, standardized as ISO/IEC 11544 and ITU-T T.82 in 1993, is a lossless image compression format primarily used for binary images, such as those in fax transmissions. Developed by the Joint Bi-level Image Experts Group, JBIG offers significant compression efficiency over previous standards, achieving up to 50% better compression than Fax Group 4. Its history dates back to 1988 when ISO and CCITT collaborated to create a unified standard for bi-level image coding.
