description MathJax Overview
MathJax is the industry-standard JavaScript display engine for mathematics on the web. It is not an editor in the traditional sense, but rather the engine that powers the rendering of equations on millions of websites, including Wikipedia and Stack Exchange. It supports LaTeX, MathML, and AsciiMath, ensuring that equations look crisp and professional on any device or browser. For developers building educational platforms or scientific blogs, MathJax is the essential tool for ensuring mathematical content is accessible, searchable, and perfectly formatted for every reader.

help MathJax FAQ
How do I add MathJax to my website?
Add the MathJax CDN script tag to your HTML head section. For LaTeX input, use the configuration code: window.MathJax = { tex: { inlineMath: [['$', '$']] } }; and load the tex-chtml.js component.
What is the difference between LaTeX, MathML, and AsciiMath in MathJax?
LaTeX is the most popular choice with extensive macros and formatting commands. MathML is a W3C standard using XML tags. AsciiMath uses simpler ASCII syntax like `sum_(i=1)^n i^2`. MathJax converts all three to accessible HTML/CSS or SVG.
Is MathJax free to use commercially?
Yes, MathJax is completely free and open source under the Apache 2.0 license. You can use it in personal, commercial, and educational projects without any licensing fees or restrictions.
How does MathJax compare to KaTeX in performance?
KaTeX generally renders faster for simple equations due to its lighter codebase, but MathJax offers broader compatibility, more input format options, and better accessibility support at the cost of slightly slower parsing.
