The KaTeX WordPress plugin enables you to use the fastest <a href="https://github.com/Khan/KaTeX" rel="nofollow ugc">TeX math typesetting engine</a> on your WordPress website. You can include TeX inside a <code>[katex]...[/katex]</code> shortcode or in a Gutenberg block. Either way the math will render beautifully on your website. When using Gutenberg blocks, the equations will render immediately inside your editor!
Equations in blocks or using the <code>[katex display=true]...[/katex]</code> shortcode will render on page in display mode–with bigger symbols–centered on their own line.
For compatibility with other LaTeX plugins, this plugin optionally supports <code>[latex]...[/latex]</code> shortcodes.

WP MathJax displays mathematical notation in web browsers, using MathML, LaTeX and ASCIIMath markup on WordPress by using MathJax.js.
WP MathJax is smart enough that loads mathjax.js only when your posts contain mathjax syntax, by detecting the use of shortcode and block. So it will not be loaded on your website everywhere.
If you are not using Guteberg editor and looking for a <a href="https://github.com/terrylinooo/githuber-md" rel="nofollow ugc">Markdown editor</a> supporting MathJax, you can also check out my WordPress plugin called the WP Githuber MD, which provides a variety of features not just MathJax, it is worth to try.
