How To Convert Markdown to Beautiful PDF

Since I’m writing documentation, tutorials and guidelines on regular basis and often spent a lot of time on formatting until I get to know Markdown. Markdown is a lightweight markup language that helps you focus on writing. I have been using Markdown for a while now and have found that it has dramatically increased my productivity. Precisely because Markdown is lightweight and easy to learn, it has become increasingly popular over the years. Another great advantage is that its simplicity makes it quite easy and efficient to convert to other formats.

A Brief Introduction to Markdown

Markdown was developed and specified by John Gruber und Aaron Swartz back in 2004 with version 1.0.1. The goal was that the source language was easy for humans to read, even before conversion. There are now several extensions and flavours of Markdown that bring more features.

Key advantages of using Markdown are:

  • Markdown is easy to learn and easy to use. You can focus on content and (once you have defined a layout) don’t have to struggle with formatting and layout.
  • You can use your favorite editor to edit Markdown (.md) files, such as Visual Studio Code, Atom, Sublime Text, which help you to focus on content, are slim and efficient.
  • You can easily search files and content, since Markdown is based on textual files and content, which is readable by humans.
  • Because Markdown is slim and efficient, it is capable to be converted in many formats, such as PDF, HTML, epub or others.
  • Since the Markdown overhead is very small and textual based, it can be synced fast and easily between various devices and services.
  • Working together with others is very easy and highly efficient, if you use a version control system like git (e. g. GitHub, GitLab) or SVN (Subversion).

Why Did I Deal With This?

If you a familiar with Markdown and ever wondered how to convert Markdown files to beautiful PDFs, you might find the answer by continue reading.

Yes, Markdown is simple, easy to learn and has a small overhead, but what if you have to provide documentation to the management, customers or other external parties? Text files usually don’t cause a wow effect and it makes a better impression if your documents have a reasonable format and follow the corporate design.

Back in the days I struggled with this until I stumbled across a repository called “Eisvogel” on GitHub, which contains a generic LaTeX-template which uses pandoc (a universal document conversion tool) to create beautiful PDFs, which can be customised. I tried a lot and initially used a local setup, following the documentation of the repository.

However, my demands and desire for automation grew, so I started converting our documents, which we host on GitHub, automatically by using GitHub Actions. Of course, it was inefficient to build an environment for each operation and wait 5-6 minutes to set it up, and then convert documents in 10-30 seconds per operation.

That is why I have built a container.

Setup Container

This setup converts Markdown files to beautiful PDFs using pandoc, TeX Live and the “Eisvogel” Markdown template within a docker container. Not all Markdown flavours are supported to pandoc limitations, but vanilla markdown works like a charm.

Used Components

  • TeX Live 2021 docker image (Debian Bookworm / Testing)
  • TeX Live add-ons:
    adjustbox babel-german background bidi collectbox csquotes everypage filehook footmisc footnotebackref framed fvextra letltxmacro ly1 mdframed mweights needspace pagecolor sourcecodepro sourcesanspro titling ucharcat ulem unicode-math upquote xecjk xurl zref
  • pandoc 2.11.2
  • Eisvogel template 2.0.0


  • Your favorite text editor
  • Docker
  • An x86_x64 compatible system (ARM not supported at the moment)

Document Folder Structure

For using this container you need following structure:

  • /docker Contains the Dockerfile for creating docker images.
  • /config Contains the yaml config files for pandoc and the Eisvogel LaTeX template (metafile).
  • /docs Contains all markdown files and assets (e. g. images).
  • /docs/assets Contains additional assets (e. g. images or pdfs) and is optional.
  • /output Contains generated PDFs. Folder and file names can be changed in the config files.
  • /templates Contains the Eisvogel LaTeX template, page layout and a logo.

You can download the sample structure here


Please clone the repo locally or if you are familar with GitHub Actions, you can use this setup to run automated PDF conversion directly on GitHub.

Build Docker Image

From the cloned directory of the repo, build the docker image. This step only needs to be performed a single time. If you don’t want to build the image by yourself, feel free to skip building and proceed with here.

docker build -t md-pdf-conversion -f docker/Dockerfile .

Setup Container

Now, simply create a container using following command. Name of the container of cause can be changed.

docker run -v /path/to/your/workdir/:/var/opt/pandoc --name md-pdf-conversion maholick/md-pdf-conversion:latest

Use Container

If you decided to build the container by your own, you can skip the next part and proceed with Creating the Container.

Using the Prebuilt Docker Image

You can find the prebuilt docker image (maholick/md-pdf-conversion), which is based on the above mentioned repository, on Docker Hub:

Download the image by using the docker pull command:

docker pull maholick/md-pdf-conversion

You should see following output:

[~] # docker pull maholick/md-pdf-conversion  
Using default tag: latest

Create the Container

After you downloaded the image, we need to create the container with docker run. Please make sure that you specify the path to the directory, with the above mentioned folder structure. You can choose any name for the container you want. The container is configured to start

docker create -v /path/to/your/workdir/:/var/opt/pandoc --name md-pdf-conversion maholick/md-pdf-conversion:latest

The container will be created and you should see a similar output:

[~] # docker create -v /path/to/your/workdir/:/var/opt/pandoc --name md-pdf-conversion maholick/md-pdf-conversion:latest

Start the Container

Now we are ready and can start the container

[~] # docker start md-pdf-conversion

and check if the container is running

[~] # docker ps
CONTAINER ID   IMAGE                               COMMAND      CREATED         STATUS          PORTS     NAMES
18a67ddaaee6   maholick/md-pdf-conversion:latest   "/"   2 minutes ago   Up 18 seconds             md-pdf-conversion

Convert Markdown to PDF

Now we are ready for our first conversion. For this we will use the example files, which are included in the repository. Please navigate to docs folder in your working directory, which you configured with the container and create the start file “.start“. The conversion starts immediately by converting all “*.md” files recursively and ordered, using the configuration in “/config“.

[/] # cd /path/to/your/workdir/docs
[/path/to/your/workdir/docs] # ls  assets/
[/path/to/your/workdir/docs] # touch .start
[/path/to/your/workdir/docs] # ls
[/path/to/your/workdir/docs] # ls -all ../output/
total 160

-rw-rw-rw- 1 demo users 146270 2022-01-24 21:12 example.pdf

You can find the converted file in the output folder of your working directory and should now see a beautiful PDF file, which was converted from Markdown, based on your adjustments within the config files.

Successful Conversion

After a successful conversion the conversion folder will be emptied. Make sure that you only copy files here.

Unsuccessful Conversion

The start-file will be removed and you can check your config for errors.
