Convert PWP to JBIG

The PWP file extension stands for PhotoWorks Image File, associated with the PhotoWorks software developed by Seattle FilmWorks. Primarily used in the late 1990s and early 2000s for storing color images, PWP files are similar to SFW files and were commonly used for image downloads from the internet. Although the software is now discontinued, PWP files can be converted to standard JPG images using specific converters.

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.
