JPEG File Interchange FormatJFIF (JPEG File Interchange Format) is a minimal file format that enables JPEG bitstreams to be exchanged between a wide variety of platforms and applications. It provides a simple structure to store JPEG-encoded images while including necessary metadata like pixel density and color space information. JFIF files typically have a .jfif extension but can also be seen with .jpg or .jpeg extensions. The format is widely supported and commonly used for web images, due to its efficiency in compressing photos with minimal quality loss.
