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
KWD is the native document format of KWord, the word processor component of KOffice (later renamed Calligra Suite), developed by the KDE community with its first stable release in KOffice 1.0 in 2000. KWord distinguished itself from other word processors through a frame-based layout model where text, images, and other content existed in independent frames that could be positioned freely on the page, similar to desktop publishing applications — a departure from the linear text-flow approach used by most word processors. KWD files store document content in a compressed XML format that describes the frame hierarchy, text content with formatting markup, paragraph styles, page dimensions, headers, footers, and embedded media. The format uses a ZIP container packaging the XML document alongside any referenced images and resources. One advantage was the flexible frame-based layout — users could position text and image frames independently on the page, enabling newsletter-style layouts and creative document designs without switching to a dedicated DTP application. The open XML structure is another benefit, making KWD files transparent and accessible to automated processing. KWord was included in several Linux distributions as part of the KDE desktop environment during the 2000s. The project was eventually discontinued in favor of Calligra Words, which adopted the ODF standard. KWD files can be opened with legacy KOffice installations or converted through document conversion tools.
