drawio2tikz 0.1.1

Convert diagrams.net/draw.io diagrams to TikZ via SVG.

drawio2tikz

drawio2tikz is a thin wrapper around svg2tikz that converts draw.io diagrams to TikZ code for embedding in LaTeX documents.

Features

• Converts either a single draw.io page or all pages
• Preserves label colors, bold text, font sizes, and simple line breaks
• Ignores draw.io font family names, allowing output to use the host LaTeX document font
• Removes draw.io SVG CSS that svg2tikz cannot parse, including light-dark(...) from draw.io's dark mode color scheme
• Restores draw.io labels emitted as SVG foreignObject elements, which draw.io exports as HTML fragments

Requirements

• Python 3.14 or newer
• drawio CLI available on PATH (install from diagrams.net or via Homebrew: brew install --cask drawio)

Installation

pip / uv

Install from PyPI:

uv tool install drawio2tikz

Or with pip:

pip install drawio2tikz

Development Setup

Clone the repository and install in development mode:

git clone https://github.com/daikiokayama/drawio2tikz.git
cd drawio2tikz
uv sync
uv run drawio2tikz --help

Usage

Basic Usage

Convert a single page from a draw.io file to TikZ:

drawio2tikz path/to/figure.drawio -o output_dir

This generates figure.tikz in the output directory.

Convert All Pages

To convert all pages in a multi-page .drawio file:

drawio2tikz path/to/multipage.drawio --all-pages -o output_dir

Each page is saved as figure_page{N}.tikz.

Keep Intermediate SVG

To debug or inspect the intermediate SVG (after sanitization):

drawio2tikz path/to/figure.drawio -o output_dir --keep-svg --svg-dir output_dir/svg

View Help

drawio2tikz --help

LaTeX Setup

Add these packages to your LaTeX document preamble:

\usepackage{xcolor}
\usepackage{tikz}

Include the generated TikZ file:

\input{path/to/figure.tikz}

For support of arbitrary large font sizes, use a scalable font:

\usepackage{mlmodern}

Example LaTeX Document

\documentclass{article}
\usepackage{xcolor}
\usepackage{tikz}
\usepackage{mlmodern}

\begin{document}

\section{My Diagram}

\begin{figure}
  \centering
  \input{figures/diagram.tikz}
  \caption{A diagram created in draw.io}
\end{figure}

\end{document}
