About formats

JFIF (JPEG File Interchange Format) is the standard file format specification for storing JPEG-compressed images, published by Eric Hamilton at C-Cube Microsystems in version 1.0 in 1991 and updated to version 1.02 in 1992. While the JPEG standard (ISO/IEC 10918-1) defines the compression algorithm — the discrete cosine transform, quantization, and entropy coding that convert pixel data into a compact bitstream — it does not specify a file format. JFIF fills this gap by defining a minimal container that wraps the JPEG bitstream with the metadata needed for interoperable display: pixel aspect ratio, resolution units (DPI or dots per centimeter), color space specification (YCbCr using CCIR 601 conversion from RGB), and an optional embedded thumbnail. The JFIF container is identified by an APP0 marker segment at the start of the file containing the ASCII string 'JFIF' and a version number. Nearly every JPEG file in existence conforms to the JFIF specification — when people refer to a 'JPEG file,' they almost always mean a JFIF file, even if the extension is .jpg or .jpeg. One advantage is universality: JFIF's simplicity and early publication date (predating competing proposals like EXIF) meant it was adopted by virtually every software and hardware platform as the baseline JPEG file format, establishing the interoperability that made JPEG the world's most widely used image format. The specification's deliberate minimalism is another strength — by defining only the essential metadata for correct display and leaving room for application-specific extensions via additional APP markers, JFIF proved extensible enough to accommodate EXIF camera data, ICC color profiles, and XMP metadata without breaking backward compatibility.
Initial release: 1991
MNG (Multiple-image Network Graphics) is an animation and multiple-image format designed as the animated counterpart to PNG, with its specification reaching version 1.0 on January 31, 2001. Developed by Glenn Randers-Pehrson and members of the PNG development community, MNG extends PNG's capabilities with support for frame-based animation sequences, slide shows, complex sprite overlays, and JNG (JPEG Network Graphics) frames for lossy compression of photographic content within the same container. An MNG file consists of a series of chunks (following PNG's chunk-based architecture): MHDR and MEND chunks bookend the datastream, with embedded PNG or JNG images as individual frames and control chunks (DEFI, FRAM, LOOP, ENDL, TERM, BACK, BASI, CLON, PAST, DISC, SHOW) directing playback timing, looping behavior, layer compositing, and memory management. The format supports both full-frame replacement and delta (difference) updates for efficient encoding of animations with static backgrounds, as well as object-based animation where sprites are defined once and repositioned across frames. One advantage is technical sophistication: MNG provides a level of animation control that GIF and APNG cannot match — frame-accurate timing, nested loops, conditional branches, interframe compression, and mixed lossy/lossless content within a single animation. The PNG-based foundation ensures lossless quality with full alpha transparency for each frame. MNG is supported by ImageMagick, GIMP, and various media players, though browser support was limited, which led to APNG's emergence as a simpler alternative for web animation.
