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.
The JNG format expertly blends JPEG's compression with PNG's transparency. Developed by the PNG Development Group, it's a member of the MNG family, designed for embedding lossy JPEG images in animations. While JNG files are more compact, they may exhibit typical JPEG compression artifacts.
