mathra
Math LaTeX to accessible SVG, without a TeX install. Every SVG carries the phrase a screen reader says, in 16 languages, and draws with the STIX Two Math font embedded, so it looks the same everywhere. Try it in the browser.
pip install mathra
Wheels for Linux, macOS and Windows, for Python 3.9 and later; nothing else to install.
Usage
import mathra
svg = mathra.tex_to_svg(r"x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}")
open("quadratic.svg", "w", encoding="utf-8").write(svg)
r = mathra.render(r"\frac{3}{4}", locale="fr")
r["speech"] # 'trois quarts'
r["warnings"] # [] — broken LaTeX is drawn anyway and reported here (E-REC-*)
mathra.tex_to_svg(r"\sum_{n=1}^{\infty} \frac{1}{n^2}", display=False) # inline style
mathra.tex_to_svg(r"\vertA\vert", strict=True) # ValueError, like TeX
mathra.render("sqrt(x)/2", input="asciimath")["speech"] # also input="mathml"
tex_to_svg(tex, locale="en", *, display=True, strict=False, input="latex", braille=None) |
The SVG as a string. |
render(tex, locale="en", *, display=True, strict=False, input="latex", braille=None) |
A dict: svg, speech, text, braille, braille_code, tree, applied, warnings. |
tex_to_tree(tex, locale="en", *, display=True, strict=False, input="latex", braille=None) |
The tree of meaning as JSON. |
locales() |
[{"code": "en", "name": "English"}, …]: en, pt-BR, es, fr, de, it, ru, zh, ja, ko, hi, ar, id, tr, nl, pl. |
input is "latex", "mathml" or "asciimath"; MathML passed as LaTeX, starting with <math, is recognized on its own. braille is "cmu" or "nemeth"; by default the locale's (CMU in pt-BR and es, Nemeth elsewhere). Errors are ValueError. Types are included (py.typed).
What it draws
Every image below is an SVG written by mathra, on a white card so it reads well on dark pages.
 Quadratic formula |  Gaussian integral |
 Matrix with dots |  Piecewise definition |
 Chemistry ( \ce) |  Units ( \SI) |
 Maxwell's equations | |
What the SVG carries
Speech in <title> linked with aria-labelledby, the source equation and the tree of meaning in <metadata>, color from the page (currentColor), size in em, a selectable text layer and ids unique to each equation. The same input always gives the same bytes, in Python and in every other package.
Also for JavaScript, Rust and the terminal
The same core is an npm package (@mathlabs/mathra), a Rust crate and a command-line tool: github.com/matheusmota-dev-br/mathra. Rules, languages and the full list of supported commands are there too.

The code is MIT or Apache-2.0; the embedded STIX Two Math font is under the SIL Open Font License 1.1.
