TeX4ht is a highly configurable TeX-based authoring system dedicated mainly to produce hypertext. It interacts with TeX-based applications through style files and postprocessors, leaving the processing of the source files to the native TeX compiler. Consequently, TeX4ht can handle the features of TeX-based systems in general, and of the LaTeX and AMS style files in particular.

Pre-tailored configurations are offered for different output formats, including (X)HTML, MathML, OpenDocument, and DocBook.
