## Description
The KaTeX WordPress plugin enables you to use the fastest [TeX math typesetting engine](https://github.com/Khan/KaTeX)
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.

The source
code is available in [the KaTeX git repository on GitHub](https://github.com/KaTeX/KaTeX/tree/v0.16.22).
## Screenshots

* KaTeX
## Installation
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.
## FAQ
### 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.
## Reviews
### [Updates again](https://wordpress.org/support/topic/updates-again/)
[gkoper](https://profiles.wordpress.org/gkoper/) 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. Ger
### [Rendering inline](https://wordpress.org/support/topic/question-427/)
[Difa](https://profiles.wordpress.org/difawa/) March 31, 2024
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!](https://wordpress.org/support/topic/rtl-equation-in-rtl-websites/)
[مرتضی رستگار](https://profiles.wordpress.org/qwerty13/) August 20, 2023 1 reply
This plugin have no options at all! and sets its direction by global direction that
means RTL equations in RTL websites!
### [Great plugiin](https://wordpress.org/support/topic/great-plugiin-4/)
[macadk](https://profiles.wordpress.org/macadk/) 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.

Fortunately, this is compatible with Elementor!
### [Nice Plugin](https://wordpress.org/support/topic/nice-plugin-4422/)
[allabakash](https://profiles.wordpress.org/allabakash/) September 26, 2021 1 reply
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.

## Changelog
#### 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](https://wordpress.org/plugins/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 `
` 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
* Upgrade KaTeX resources to v0.10.2.
#### 1.0.3

#### 1.0.0
* Initial release.
