Convert AVIF to PJPEG

AVIF, or AV1 Image File Format, is a modern image format derived from the AV1 video codec developed by the Alliance for Open Media. It is designed to deliver high-quality images with superior compression efficiency compared to traditional formats like JPEG and PNG. This format supports advanced features such as HDR (High Dynamic Range), WCG (Wide Color Gamut), 10-bit color depth, and alpha transparency, making it ideal for web developers and digital content creators seeking to optimize performance and visual fidelity. Introduced in 2018, AVIF has rapidly gained adoption due to its open-source nature and effectiveness in reducing file sizes without compromising quality.

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.
