About formats

AW is the document format of Applix Words, the word processor component of the Applix office suite (later renamed Anyware Office) developed by Applix, Inc. for Unix and Linux workstations. The suite targeted enterprise Unix environments during the 1990s, providing word processing, spreadsheet, graphics, and presentation capabilities on platforms like Solaris, HP-UX, AIX, and Linux where Microsoft Office was unavailable. AW files store formatted text documents with support for character and paragraph styling, page layout, tables, headers and footers, and embedded graphics. The format uses a proprietary binary structure optimized for the Applix application's internal document model. Applix Words gained particular visibility in the Linux community during the late 1990s when it was bundled with several commercial Linux distributions as their default word processor before OpenOffice.org became widely available. One advantage was native Unix platform support — Applix provided professional word processing capabilities on Unix workstations at a time when few commercial alternatives existed. The format's tight integration with other Applix suite components enabled cross-referencing between word processing documents, spreadsheets, and presentations. Applix was acquired by Cognos in 2003, and the office suite was discontinued. AW files are primarily encountered today in archived documents from Unix enterprise environments of the 1990s and early 2000s.

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.

Frequently Asked Questions

What is the FAX format?

FAX is a TIFF-based image format using Group 3 fax compression — optimized for transmitting documents over fax lines.

Why convert AW to FAX?

If you need to send old AW document content via fax, the FAX format is optimized for that transmission method.

What opens FAX files?

Windows Fax Viewer, IrfanView, XnView, and fax software applications can open and display FAX image files.

Is this free?

Yes — AW to FAX conversion is free. Premium plans provide extended capabilities for power users.

Is the output black-and-white?
