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
PNG (Portable Network Graphics) is a lossless raster image format developed by the PNG Development Group and published as a W3C Recommendation on October 1, 1996, created as a patent-free replacement for GIF after the Unisys LZW patent controversy. PNG uses a two-stage compression pipeline: a prediction filter selects the optimal per-row preprocessing (none, sub, up, average, or Paeth), then DEFLATE compression encodes the filtered data. The format supports rich color modes — 1/2/4/8/16-bit grayscale, 8/16-bit per channel true color, and indexed color with palettes up to 256 entries — all with optional alpha transparency ranging from a single transparent color to a full per-pixel alpha channel with 256 or 65536 levels. PNG also stores gamma correction, ICC color profiles, text metadata, and suggested background color. One advantage is lossless compression with transparency — PNG preserves every pixel exactly while supporting smooth semi-transparent edges, making it the standard format for web graphics, UI elements, logos, screenshots, and any image where artifacts or color shifts are unacceptable. Universal support is another core strength: every web browser, operating system, image editor, and programming library handles PNG natively. The format has proven remarkably durable — after nearly three decades, PNG remains the default lossless web image format. While newer formats like WebP and AVIF offer better compression, PNG's combination of lossless quality, full transparency, and absolute ubiquity keeps it indispensable.
Initial release: October 1, 1996
