By default, all software supports multiple file extensions. LaTeX supports at least 16 different file extensions. The basic files that LaTeX supports are .IDX. However, not all of the extensions listed on the list are always used to save the effects of work in LaTeX. Very often, files with such extensions are used as source data files used by LaTeX.
LaTeX can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via LaTeX and try to save it in another file format, also supported by LaTeX.
