Convert PSB to JBIG

The PSB (Photoshop Large Document Format) file extension is utilized for handling exceptionally large images in Adobe Photoshop. Introduced to support projects exceeding the limitations of the traditional PSD format, PSB is optimized for files that surpass 30,000 by 30,000 pixels, accommodating up to 300,000 pixels in either dimension. This format is essential for professional photographers, graphic designers, and digital artists who work with high-resolution images, providing a robust solution for maintaining the integrity and quality of detailed visuals in complex projects. PSB's development has been integral to Adobe's efforts to enhance the capacity and efficiency of its image editing software, ensuring that professionals can work without restrictions on image size and complexity.

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.
