Convert JPG to PJPEG

Understanding jpg and pjpeg file formats

JPG (or JPEG) is a widely used raster image format known for its efficient compression and compatibility across devices and platforms. It is commonly used for digital photos and web images due to its balance between image quality and file size.

PJPEG stands for Progressive JPEG. Unlike standard JPGs, pjpeg files are encoded so that images load in successive waves of increasing detail, making them appear to load faster on slow connections. This format is especially useful for web applications where user experience is a priority.
