DVI ("DeVice Independent") is the output file format of the TeX typesetting program. Unlike the TeX markup files used to generate them, DVI files are not intended to be human-readable; they consist of binary data describing the visual layout of a document in a manner not reliant on any specific image format, display hardware or printer (hence the DVI format's name). DVI files are typically used as input to a second program (called a DVI driver) which translates DVI files to graphical data. For example, most TeX software packages include a program for previewing DVI files on a user's computer display; this program is a driver. Drivers are also used to convert DVI files to popular document formats (e.g. PostScript, PDF) and for printing. Wikipedia uses a PNG driver to generate graphics for mathematical formulae in articles.

DVI is not a document encryption format, and TeX markup may be at least partially reverse-engineered from DVI files, although this process is unlikely to produce high-level constructs identical to those present in the original markup, especially if the original markup used high-level TeX extensions (e.g. LaTeX).

Publishers who require submissions in TeX format will generally reject DVI files not accompanied by TeX markup files.
