About formats

SIXEL (Six Pixel) is a bitmap graphics encoding format created by Digital Equipment Corporation (DEC) in 1983 for rendering images on character-cell printers and video terminals. The name derives from the encoding's fundamental unit: a column of six pixels represented by a single ASCII character. Each printable character in the sixel data stream (ASCII 63-126) encodes a 6-pixel vertical column, with the character's binary value determining which pixels are on or off. Color is specified through register-based palette control: a Select Color Sequence assigns an HLS or RGB color value to a numbered register, and subsequent sixel characters use that color until another register is selected. The encoding supports raster attributes for specifying pixel aspect ratio and image dimensions, repeat sequences (! followed by a count and character) for run-length compression of identical columns, and $ (carriage return) and - (new line) for navigating the sixel grid. DEC implemented SIXEL support in their VT240, VT241, VT330, and VT340 terminals, as well as multiple printer models. One advantage of the SIXEL encoding is its ASCII-clean nature: the data stream consists entirely of printable characters and standard control sequences, meaning SIXEL graphics can be transmitted through any text-based communication channel — serial terminals, SSH sessions, telnet connections — without requiring binary-safe transport or protocol modifications. The format's modern renaissance provides another remarkable dimension: after decades of obscurity, SIXEL support has been implemented in numerous contemporary terminal emulators, enabling inline image display in command-line workflows. SIXEL output can be generated by ImageMagick, libsixel, chafa, and various plotting libraries.

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 SIXEL to ABW?

Terminal-rendered SIXEL graphics are confined to the command line. Converting to ABW makes them usable across all platforms and apps.

What programs can open ABW?

AbiWord is the native editor. LibreOffice Writer can import ABW files, and some online converters render the document content.

Does SIXEL to ABW preserve quality?

ABW preserves image data without lossy compression, so the visual content from your SIXEL is retained faithfully during conversion.

How quickly can I convert SIXEL to ABW?

Conversion is handled on cloud servers and usually completes in a few seconds. Larger or higher-resolution SIXEL images may take slightly longer.

Can I convert multiple SIXEL images at once?

Batch conversion is supported. Queue as many SIXEL files as you need and convert them all to ABW in a single run — no repeating steps manually.
