About formats

FAX is a generic image file extension associated with facsimile transmission formats standardized by the ITU-T (formerly CCITT), with the underlying Group 3 compression standard ratified in 1980. FAX files typically contain monochrome (1-bit, black and white) image data compressed using the Modified Huffman (MH) encoding defined in ITU-T Recommendation T.4, which assigns variable-length codes to run lengths of consecutive white or black pixels along each scanline. The standard resolution for Group 3 fax is 204x98 dpi (normal mode) or 204x196 dpi (fine mode), reflecting the capabilities of thermal and laser fax machines of the era. FAX files encountered digitally are often raw Group 3 encoded bitstreams or TIFF wrappers with CCITT Group 3 compression (TIFF compression tag 3). The Group 3 encoding scheme is highly efficient for typical business documents — pages with mostly white space and black text — achieving compression ratios of 10:1 to 20:1 compared to uncompressed bitmaps. One advantage is universal fax system compatibility: Group 3 encoding is the mandatory baseline for all fax machines worldwide, meaning FAX files contain data in exactly the format transmitted over telephone lines, preserving the original fax data without transcoding losses. The format's role in business communications history provides another dimension — billions of fax transmissions using this encoding moved legal documents, medical records, and business correspondence for decades, and archived FAX files represent an important documentary record. FAX images can be viewed and converted using LibreOffice, ImageMagick, GIMP, and standard document management systems.

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.
