Convert JBIG to EPSF

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.

An EPSF, or Encapsulated PostScript File, is a graphics file format used primarily in the publishing and printing industries for embedding high-resolution images within other PostScript documents. Introduced by Adobe Systems in the late 1980s, EPSF files enable seamless integration of complex visual elements, maintaining quality and device independence. They encapsulate both vector and raster graphics, allowing detailed illustrations and photographs to be embedded without loss of resolution, facilitating professional-quality output across various platforms and devices.
