tikra
TikZ and pgfplots figures to SVG and PNG, without a TeX install: no LaTeX, no fonts on the system, no external processes. It reimplements TikZ, pgf and pgfplots, and labels are set by mathra in Latin Modern, TeX's own Computer Modern. Try it in the browser · See the gallery.
pip install tikra
Wheels for Linux, macOS and Windows, for Python 3.9 and later; nothing else to install.
Usage
import tikra
svg = tikra.tikz_to_svg(r"""
\begin{tikzpicture}
\draw[->] (0,0) -- (2,1) node[right] {$\vec v$};
\end{tikzpicture}
""")
open("v.svg", "w", encoding="utf-8").write(svg)
open("v.png", "wb").write(tikra.png(svg, dpi=300))
r = tikra.render(r"\tikz \draw (0,0) circle (1);")
r["warnings"] # [] — what tikra skips or approximates is listed here, and the rest is drawn
r["alt"] # 'Drawing of one shape, without text' — the figure in words, for those who cannot see it
tikz_to_svg(code, *, locale="en") |
The SVG as a string. locale (en, pt-BR, es, fr, de, it, ru, zh, ja, ko, hi, ar, id, tr, nl, pl) is the language of the figure in words; the drawing is the same in all. |
render(code, *, locale="en") |
A dict, the words in locale: svg; alt, the figure in one sentence (the SVG's <title>, for an image's alt text); description, the figure in words (the SVG's <desc>: a chart's axes and data, a diagram's nodes and connections); and warnings (a list of strings). When the picture has its author's text (\begin{tikzpicture}[alt={…}]), alt and description are that text. The words tikra writes are not perfect (they say what is in the drawing, not what it means, and little about free drawings): review them before publishing. |
png(svg, *, dpi=300, background=True) |
PNG bytes; background=False keeps it transparent instead of white. |
code is a full standalone document, a bare tikzpicture, an inline \tikz, an axis environment or loose TikZ statements. Errors (no figure in the input, an invalid dpi, a PNG past 100 megapixels) are ValueError. Types are included (py.typed).
What it draws
Every image below is an SVG written by tikra from a figure in the repository's corpus, on a white card; the gallery has all 227. Of the 2502 figures of the TikZ and pgfplots manuals, tikra draws 93.1% as TeX does (95.4% of the ones a converter can reproduce): docs/conformance.md.
 The Lorenz attractor, colored by height |  Nightingale's rose of the causes of mortality |
 The bell curve and the 68–95–99.7 rule |  The Petersen graph |
 A Feynman diagram, with decorations |  The golden spiral |
 The periodic table, by family |  A pgfplots surface and its colorbar |
Paths, nodes and every shape library, matrices, trees, graphs, mind maps, automata, circuits, arrow tips, shadings, fadings, patterns, decorations, pgfplots in 2D and 3D (polar, ternary, Smith charts, fill between, colormaps) and data visualization. What tikra does not understand becomes a warning, never a failure: the full subset is in spec/subset.md.
Also for JavaScript, Rust and the terminal
The same core is an npm package (@mathlabs/tikra), a Rust crate and a command-line tool: github.com/matheusmota-dev-br/tikra.
