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.
The PJPEG (Progressive JPEG) is a file extension for images that enhances the standard JPEG format by displaying images in successive waves of increasing detail, improving the user experience during slow network conditions. The JPEG stands for "Joint Photographic Experts Group", the organization that developed the standard in 1992. PJPEG is particularly useful for web applications, as it allows images to appear more quickly and progressively refine in quality, rather than loading from top to bottom like baseline JPEGs.
