Temml is a LaTeX-to-MathML JavaScript conversion utility. It is built to be lightweight.
| Library | Minified JavaScript + CSS |
|---|---|
| Temml | 144 KB |
| MathJax 2.7.5 | 338 KB |
| KaTeX | 280 KB |
| TeXZilla | 168 KB |
As a futher advantage, Temml can use local system fonts. The minimum Temml installation serves a font file that is only 12kb.
Temml’s MathML output conforms to both both MathML 3 (Firefox) and MathML Core (Chromium). When the MathML-in-Chromium project is complete, all the major browsers will support MathML and Temml will become the most lightweight way to render math in a browser.
Temml’s coverage of LaTeX functions is as good as MathJax, slightly better than KaTeX 0.13.0 and substantially better than TeXZilla. See a detailed coverage comparison.
Temml's test suite includes many rendered examples that are available for viewing.

I built Temml by:
-
Forking KaTeX.
-
Deleting half the code, removing the HTML parts and keeping the parser, the macro expander, and the MathML parts.
-
Doing some code refactoring and many MathML bug fixes.
-
Adding new functionality: upright lower-case Greek letters,
\euro,\label{…},\ref{…},\prescript,\definecolor,xcolorcolor names, etc.
I wish to thank Khan Academy and the many volunteer KaTeX contributors. This library would not exist if KaTeX had not existed first.
