Convert JPEG to PJPEG

JPEG, short for Joint Photographic Experts Group, is a widely-used image file format for compressing digital photographs. Established in 1992 by the Joint Photographic Experts Group, it revolutionized digital imagery by providing efficient, lossy compression that maintains significant image quality. Primarily used in digital cameras, web graphics, and image sharing, JPEG files support full-color imaging with 24-bit depth, enabling detailed and high-quality photographs in relatively small file sizes.

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.
