Type an expression: % \f is defined as #1f(#2) using the macro \f\relax{x} = \int_{-\infty}^\infty \f\hat\xi,e^{2 \pi i \xi x} ,d\xi

See how it renders with KaTeX:

Simple API, no dependencies – yet superfast on all major browsers.

• Fast: KaTeX renders its math synchronously and doesn’t need to reflow the page.
• Print quality: KaTeX’s layout is based on Donald Knuth’s TeX, the gold standard for math typesetting.
• Self-contained: KaTeX has no dependencies and can easily be bundled with your website resources.
• Server side rendering: KaTeX produces the same output regardless of browser or environment, so you can pre-render expressions using Node.js and send them as plain HTML.

Lightning-fast, even on pages with hundreds of expressions:
