KaTeX

Description

The KaTeX WordPress plugin enables you to use the fastest TeX math typesetting engine on your WordPress website. You can include TeX inside a [katex]...[/katex] 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 [katex display=true]...[/katex] 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 [latex]...[/latex] shortcodes.

Plugin Website

Assets

This plugin includes minified assets provided by the KaTeX project.
The source code is available in the KaTeX git repository on GitHub.

  1. Upload the katex folder to your /wp-content/plugins/ directory or automatically download and install the plugin through WordPress’s plugin manager;
  2. Activate the plugin in WordPress; and
  3. Use the [latex] shortcode or KaTeX Gutenberg blocks in your posts and pages.
  1. Preview your TeX right inside the editor.

    Preview your TeX right inside the editor.

  2. TeX is rendered inside your visitors' browsers.

    TeX is rendered inside your visitors' browsers.

Can I move from LaTeX plugin X to this plugin?

You should be able to replace any other LaTeX plugin using [latex] shortcodes without having to make changes to existing posts. Other plugins might handle display-mode latex other than [latex display=true]...[/latex], in which case old posts unfortunately have to be changed.

Updates again

By gkoper on July 25, 2025

Thanks to Tom for reopening this plugin for updates. It must have been a chore to satisfy the "administrators" but the result is great. I have been using KaTeX all the time. WordPress complained about lack of updates where there was no real reason other than administrative. I am sure also in the future, updating only means adapting to new rules.

Rendering inline

Is it possible to render KaTeX for inline mode in a paragraph (Gutenberg preview)? Please consider this in next update.

RTL equation in RTL websites!

This plugin have no options at all! and sets its direction by global direction that means RTL equations in RTL websites!

Great plugiin

By macadk on September 12, 2022

This is a great plugin for everyone who wants to use the power of LaTeX or KaTeX to display properly typeset math on their site. My favourite aspect of this plugin is how the Ka block displays a preview of the formatted text. While you can insert KaTeX statements using the shortcode block, if you do that, then the equations will be left justified, and there is little to do about it. Using the KaTeX block, the calculations will be properly centred between the margins set by your theme. Great job by the developer! I hope that the plugin will continue to be maintained so that we don't lose compatibility with the latest versions of WordPress, as there are very few options otherwise.

Versatile

Fortunately, this is compatible with Elementor!

Nice Plugin

By allabakash on September 26, 2021

Veny nice plugin. Able to use very easily and without any issues. A cakewalk if you know latex syntax. Rendering is very fast too. There is lot of accounting related math content on my site (eduxir.com) which requires to use math equations. Was able to achieve very easily. One request to the author is that the font and related files are downloaded even on the pages that do not use katex. We need to modify the plugin to disable this option. If a configuration option that could be provided which would retain the configuration even after updating the file, would be of great help.

Amazing support.

I am writing a lot of equations these days and I am in love with this plugin.

Excellent Plugin

By examenmalin on November 1, 2020

The rendering for displaying equations is very good. Better than other plugins. The support is responsive and provides clear and working solutions.

Excellent support

Kudos to the author of this plugin for their incredible support!

2.2.5

  • As per WordPress’s guidelines, remove the ability to fetch KaTeX resources through jsDelivr’s CDN.
  • Various internal improvements based on WordPress’s Plugin Check.

2.2.4

  • Upgrade KaTeX resources to v0.16.22.

2.2.3

  • More robustly render shortcodes (even more robustly than 2.2.2).

2.2.2

  • More robustly render shortcodes.
  • Fix undefined variable notice.

2.2.1

  • Trigger rendering of KaTeX in more cases when the DOM is mutated (in 2.2.0, accidentally only a limited set of cases was checked).

2.2.0

  • Trigger rendering of KaTeX when the DOM is mutated by inserting a .katex-eq node. This allows rendering KaTeX markup that is not present when the page is loaded.
  • Upgrade KaTeX resources to v0.13.13.

2.1.2

  • Always load JavaScript and CSS assets by default. An option is introduced to switch to the old behavior of loading only when KaTeX is used on the page.
  • Make it easier for other code to manually trigger rendering of KaTeX.
  • Upgrade KaTeX resources to v0.13.0.

2.1.1

  • Remove <br> tags added by WordPress to shortcode output.

2.1.0

  • Prevent WordPress from texturizing KaTeX (prior to this change, WordPress would sometimes change e.g. apostrophes to quotation marks).
  • Fix issue where custom class names on the KaTeX block sometimes broke editor rendering.
  • Add some keywords to allow searching for the KaTeX block in the editor’s block list.
  • Update KaTeX resources to v0.12.0.

2.0.2

  • Fix block editor variable scoping.

2.0.1

  • Upgrade KaTeX resources to v0.11.1.

2.0.0

  • Support adding CSS classes to KaTeX Gutenberg Blocks to help with styling. Backwards compatibility note: KaTeX Gutenberg Blocks are now rendered wrapped in a div element on which classes wp-block-katex-display-block and katex-eq are set. You can add more classes to this div through WordPress’s post editor. Previously, KaTeX Gutenberg Blocks were rendered wrapped in an unclassed span. KaTeX shortcodes are still wrapped inside a span with only the class katex-eq set. If you depend on old behavior for styling, you might need to update your styling rules.

1.0.5

  • Fix 1.0.4 release issue: KaTeX resources were not committed correctly.

1.0.4
