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.

ABW is the native document format of AbiWord, a free and open-source word processor originally developed by AbiSource in 1998 and later maintained as part of the GNOME Office suite. The format stores document content as well-formed XML, describing paragraphs, character formatting, page layout, headers and footers, tables, lists, footnotes, and embedded images in a human-readable structure. ABW files use a straightforward markup where document sections map to XML elements with attribute-based styling, making the format transparent and easy to parse programmatically. AbiWord was designed as a lightweight alternative to heavyweight office suites, running efficiently on older hardware and resource-constrained systems while still providing core word processing functionality. One advantage is the clean XML foundation — ABW files can be inspected, transformed, and generated using standard XML tools and scripting languages without requiring the AbiWord application itself. The lightweight nature of both the format and its parent application is another practical strength: AbiWord and its ABW format are commonly found on Linux distributions targeting older computers and educational deployments in developing countries through projects like OLPC. ABW files can be converted to mainstream formats like DOC, ODT, and PDF through AbiWord's built-in export or through document conversion tools.

Frequently Asked Questions

Why convert FAX to ABW?

FAX files need ABW conversion for proper archival, text extraction, and integration into modern document systems.

What software opens ABW?

Use AbiWord, LibreOffice Writer, or Calligra Words to view ABW files.

Is any detail lost during conversion?

FAX files are typically monochrome scans. The converter maintains full resolution and sharpness in ABW output.

Does the FAX to ABW converter cost anything?

The converter is free for standard use. Premium plans offer expanded limits and priority queue access.

Can I batch convert FAX to ABW?

Upload multiple FAX files together — the converter processes each one and delivers separate ABW outputs.

Do I need to install any software?

No installations needed. The FAX to ABW conversion runs entirely in your browser — nothing to download or set up.
