LaTeX support for Jekyll.


jekyll-t4j is a Jekyll plugin providing (nearly) full support of LaTeX.

  • Comprehensive: support almost all packages, including tikz, chemfig, etc.
  • Highly optimized: employ KaTeX to boost speed. Use cache, precompiled preamble, bulk rendering.
  • Server side rendering: all stuffs are done in server.

T4J integrates Jekyll with your local TeX distribution, so you need to have either MikTeX or TeX Live installed.

Feel free to write any LaTeX! 🎉

Warning T4J now is in rapid development, it's pretty unstable. So don't forget to check and update frequently.

Getting Started

Let's start by a simple instance, write a post and fill it with:

layout: default
title:  Hello LaTeX
date:   2023-02-04 14:53:32 +0800

This is an inline math $r=\sqrt{x^2+y^2}$.


And this is vanillyl alcohol.

As you can see, its usage is the same as KaTeX or MathJax, but we only allow delimiters $...$, $$...$$, \(...\), \[...\].

Because we use the chemfig package, so open your _config.yml file and write:

    - chemfig

Finally, build your site, complete!

You can learn more about T4J here.


First of all, you need to have a TeX distribution. Just download and install MikTeX or TeX Live. Other TeX distirbution is also available.

Then, install jekyll-t4j like other Jekyll plugins. Add this line to your application's Gemfile:

gem 'jekyll-t4j'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jekyll-t4j

Lastly, add it to your _config.yml file:

    - jekyll-t4j
