Advanced tools
KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web.
KaTeX is compatible with all major browsers, including Chrome, Safari, Firefox, Opera, Edge, and IE 11.
KaTeX supports much (but not all) of LaTeX and many LaTeX packages. See the list of supported functions.
Try out KaTeX on the demo page!

You can also download KaTeX and host it yourself.
For details on how to configure auto-render extension, refer to the documentation.
Call katex.render to render a TeX expression directly into a DOM element.
For example:
katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, {
throwOnError: false
});
Call katex.renderToString to generate an HTML string of the rendered math,
e.g., for server-side rendering. For example:
var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", {
throwOnError: false
});
// '<span class="katex">...</span>'
Make sure to include the CSS and font files in both cases. If you are doing all rendering on the server, there is no need to include the JavaScript on the client.
The examples above use the throwOnError: false option, which renders invalid
inputs as the TeX source code in red (by default), with the error message as
hover text. For other available options, see the
API documentation,
options documentation, and
handling errors documentation.
