About formats

PWP is a proprietary image format used by Seattle FilmWorks (later renamed PhotoWorks) for their internet-based photo delivery service in the mid-to-late 1990s. When customers mailed film rolls to Seattle FilmWorks for developing, the company offered a Pictures Online service that let users download their scanned photos through a dial-up internet connection. PWP files were the format used for these online downloads, containing JPEG-compressed image data wrapped in a proprietary container with additional metadata for the PhotoWorks viewing software. The format was intentionally tied to Seattle FilmWorks' proprietary desktop viewer application (PhotoMail), which customers needed to install to view and manage their downloaded photos. PWP represented one of the earliest attempts at digital photo delivery — bridging the gap between traditional film processing and the emerging internet, at a time when most consumers had no other way to get digital copies of their photographs. One advantage of the PWP format's historical context is that it preserves scanned film images from a transitional era when few consumers owned digital cameras or scanners, making PWP files potentially the only digital record of photographs from that period. The format's JPEG-based internal structure is another practical consideration: despite the proprietary wrapper, the underlying image data uses standard JPEG compression, and tools like ImageMagick, XnView, and dedicated PWP converters can extract the images for viewing in any modern application.

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.
