markdawn

A Markdown-to-HTML converter with math support, designed to produce textbook-quality, beautifully readable documents.

Pronunciation: /ˈmɑːrkdɔːn/

The name markdawn is a play on md (markdown) + dawn — the goal is to produce documents that are cleaner and more readable than plain Markdown, like a new dawn for your notes.

Features

  • Math rendering powered by KaTeX (LaTeX-style equations work out of the box)
  • Textbook-style appearance — clean typography suitable for study notes, reports, or polished LLM outputs
  • Syntax highlighting for code blocks via highlight.js (multiple themes available)
  • Single-file HTML output — easy to share, host, or print
  • Customizable header, subtitle, accent color, and language

Installation

pip install markdawn

Usage

From the command line

The basic form is:

markdawn input.md

This produces input.html next to the source file.

Available options:

Option Default Description
input (required) Input Markdown file
-o, --output same name with .html Output HTML file path
--title H1 or filename Title shown in the header bar
--subtitle (empty) Subtitle shown in the header bar
--accent #2c5f8a Accent color (hex code)
--lang ja lang attribute of the HTML (e.g. ja, en)
--hl-theme atom-one-light highlight.js theme name (e.g. github, github-dark, monokai, vs2015)

Example:

markdawn notes.md -o notes.html --title "Lecture 3" --subtitle "Linear Algebra" --accent "#8a2c5f" --lang en --hl-theme github-dark

From Python

import markdawn

markdawn.convert("input_filename.md")

When to use markdawn

  • Turning LLM responses into clean, shareable documents
