PGF/TikZ is a pair of languages for producing vector graphics from a geometric/algebraic description. PGF is a lower-level language, while TikZ is a set of higher-level macros that use PGF. The top-level PGF and TikZ commands are invoked as TeX macros, but in contrast with PSTricks, the PGF/TikZ graphics themselves are described in a language that resembles MetaPost. Till Tantau is the designer of these languages, and he is also the main developer of the only known interpreter for PGF and TikZ, which is written in TeX. PGF is an acronym for "Portable Graphics Format". TikZ was introduced in version 0.95 of PGF, and it is a recursive acronym for "TikZ ist kein Zeichenprogramm" (German for "TikZ is not a drawing program").

The PGF/TikZ interpreter can be used from the popular LaTeX and ConTeXt macro packages, and also directly from the original TeX. Since TeX itself is not concerned with graphics, the interpreter supports multiple TeX output backends: dvips, dvipdfm/dvipdfmx/xdvipdfmx, TeX4ht, and pdftex's internal PDF output driver. Unlike PStricks, PGF can thus directly produce either PostScript or PDF output, but it cannot use some of the more advanced PostScript programming features that PStricks can use due to the "least common denominator" effect.[1] PGF/TikZ comes with extensive documentation. The version 3.0.0 manual has 1165 pages.

The standard LaTeX `picture` environment can also be used as a front end for PGF merely by using the `pgfpict2e` package.

Several graphical editors can produce output for PGF/TikZ like the KDE program Cirkuit,[2] and the math drawing program GeoGebra. Export to TikZ is also available as extensions for Inkscape,[3] Blender,[4] MATLAB,[5] matplotlib,[6] Gnuplot[7] and R.[8]

The project has been under constant development since 2005. Most of the development is done by Till Tantau.[9] Version 3.0.0 was released on 2013-12-20.[10] One of the major new features is graph drawing using the `graphdrawing` package, which however requires LuaTeX.[11] This version also added a new data visualization method and support for direct SVG output via the new dvisvgm driver.[12]
