Title: Simple Mathjax Author: Samuel Coskey Published: September 20, 2011 Last modified: September 10, 2025 --- Search plugins ![](https://s.w.org/plugins/geopattern-icon/simple-mathjax.svg) # Simple Mathjax By [Samuel Coskey](https://profiles.wordpress.org/sgcoskey/) [Download](https://downloads.wordpress.org/plugin/simple-mathjax.2.1.1.zip) * [Details](https://wordpress.org/plugins/simple-mathjax/#description) * [Reviews](https://wordpress.org/plugins/simple-mathjax/#reviews) * [Installation](https://wordpress.org/plugins/simple-mathjax/#installation) * [Development](https://wordpress.org/plugins/simple-mathjax/#developers) [Support](https://wordpress.org/support/plugin/simple-mathjax/) ## Description This wordpress plugin is yet another simple plugin to load the [MathJax](http://www.mathjax.org) scripts at the bottom of all of your pages. It uses a very all-inclusive mathjax configuration by default, with $’s and $$’s the default delimeters for in-line and displayed equations. A preference pane is added to the “Settings” group where you can choose whether to use MathJax version 2 or 3, change the MathJax server location (CDN) and the MathJax configuration settings. (See [the mathjax documentation](https://docs.mathjax.org/en/latest/web/start.html#configuring-mathjax) for details on the options available.) You can also specify a LaTeX “preamble” of newcommands which will be loaded in a hidden element near the top of each page. Fork this plugin on [GitHub](https://github.com/boolesrings/Simple-Mathjax-wordpress-plugin). ## Installation Nothing unusual here! ## Reviews ![](https://secure.gravatar.com/avatar/67d845721a80c9c4969b5d0e6a1d6768e0b838ee97ad043fb6555fd1c9008c77? s=60&d=retro&r=g) ### 󠀁[My preferred MathJax plugin out of the 3 I’ve tried](https://wordpress.org/support/topic/my-preferred-mathjax-plugin-out-of-the-3-ive-tried/)󠁿 [tinacious](https://profiles.wordpress.org/tinacious/) May 15, 2026 I will preface this review with the statement that I am not a math expert and that I do not personally write LaTeX, though I do understand some basics about the syntax, so take this review with a grain of salt. This is my preferred MathJax plugin. I’ve tried 2 other plugins that can render LaTeX (1 KaTeX, 1 MathJax) and here are some reasons I prefer this one: Custom config: I’m able to provide custom configuration of the window.MathJax object which is very helpful, allowing me to configure custom macros, which I needed to do in order to support dark mode for some of the colourized syntax my client uses. Custom CDN: I’m able to configure the CDN that the plugin pulls from. I experienced a performance issue on one of my client’s pages. Unfortunately this plugin caused the tab to crash on one of my client’s pages (a page with a lot of LaTeX). I was able to debug the issue and see that it was coming from font loading. I don’t know enough about MathJax and LaTeX to understand why the font loading was triggered on this one specific page and not others, but I did see it was related to the font loading. Choosing a Cloudflare URL without fonts instead of the default jsDelivr one with fonts was the workaround I used. I’d provide the specific CDN URLs here but the review guidelines say no URLs allowed. Non-developers would likely have trouble debugging this issue, so it might be helpful if the developer chooses to use a version without fonts by default, or surface the performance risks in the configuration. I’m also not sure what will break by omitting the fonts but LaTeX content seem to be working fine for the time being after providing a custom CDN URL. Supported everywhere: This plugin supports native MathJax syntax anywhere on the site, not just in post and page bodies, and doesn’t require the use of shortcodes. My client uses MathJax in menu links and in page titles so it’s super helpful that this plugin isn’t restricted to post and page content. Out of the 3 MathJax and LaTeX plugins I tried, this one seems to be my preferred version for the time being. ![](https://secure.gravatar.com/avatar/80a79c36e9f2c97d8460a779beb8ebf9442d9ac1fc3f607760c63819f106879c? s=60&d=retro&r=g) ### 󠀁[Incompatible with WP version 6.7](https://wordpress.org/support/topic/incompatible-with-wp-version-6-7/)󠁿 [wengs](https://profiles.wordpress.org/wengs/) November 13, 2024 The plugin is great, but it’s not compatible with WP6.7, I used math symbols in $xxx$ format in the text, and it still shows $xxx$, no change, it only shows the formula correctly when I use math symbols in $$xxx$$! Still need to wait for the update ![](https://secure.gravatar.com/avatar/30fc91004637c9c0761bfc6219cf97e40bedae4fac177998d4f5b430f561a7c5? s=60&d=retro&r=g) ### 󠀁[Excellent Plugin](https://wordpress.org/support/topic/excellent-plugin-6210/)󠁿 [sebasmurgue](https://profiles.wordpress.org/sebasmurgue/) August 20, 2020 This plugin has been very useful for our website. It simply works, and it works well. We have been able to add some customization (for example to number the equations) without problem. I highly recommended it if you want to have MathJax in your wordpress site! ![](https://secure.gravatar.com/avatar/cf65989ca2f27b1f67a5036ca3b2fd134a958d00f208b92f67362dc024dc3f13? s=60&d=retro&r=g) ### 󠀁[Works as expected](https://wordpress.org/support/topic/works-as-expected-585/)󠁿 [edwardw](https://profiles.wordpress.org/edwardw/) July 6, 2020 Works as expected on 5.4.2! ![](https://secure.gravatar.com/avatar/6b73a85a58fe419734d2e659a331f3b8fe76f7fb9c89ad8a1904cf81a00cf306? s=60&d=retro&r=g) ### 󠀁[Great! Can use on specific pages](https://wordpress.org/support/topic/great-can-use-on-specific-pages/)󠁿 [hrd123](https://profiles.wordpress.org/hrd123/) June 19, 2020 1 reply Really like this plugin. It’s quick and very easy to use; the best Latex plugin I’ve tried. I initially had a problem where I only wanted to load the Mathjax on certain pages, and I found the solution was to install a separate plugin which lets you toggle all of your other plugins on and off on each page/post. ‘Plugin Load Filter’ worked for me, but it might not be useful to everyone though. ![](https://secure.gravatar.com/avatar/fa1d3907b6b9bb7c0cf7e424c3fbda8f499726792fd07f4602a6c7c482e12c69? s=60&d=retro&r=g) ### 󠀁[Top plugin, everything as described!](https://wordpress.org/support/topic/top-plugin-everything-as-described/)󠁿 [ars111](https://profiles.wordpress.org/ars111/) May 24, 2020 I would say that this is the best plugin that renders MathJax! I would recommend it to anyone who needs to use LateX on their website.
