Convert SVG to LaTeX

Why Convert SVG to LaTeX?

Converting SVG to LaTeX enables you to include vector graphics directly in academic papers, theses, and scientific publications as native TikZ code. This ensures that fonts, line weights, and text within diagrams match the surrounding document perfectly, producing professional, publication-quality results.

SVG diagrams created in tools like Inkscape, Figma, or D3.js often need to be embedded in LaTeX documents. While LaTeX can include SVG as external images, converting the graphic to TikZ code allows the LaTeX engine to render it natively, ensuring consistent typography and enabling direct modification of the graphic within the LaTeX source.

This conversion is especially valuable for researchers and engineers who create technical diagrams, flowcharts, or data visualizations in SVG format and need to incorporate them into papers submitted to journals and conferences that require LaTeX source files.

Our converter parses SVG elements including shapes, paths, text, and colors, then generates equivalent TikZ drawing commands that can be compiled with any standard LaTeX distribution.

Key Benefits of Converting SVG to LaTeX:

• Native Integration: Embed graphics directly in LaTeX documents as TikZ code
• Font Consistency: Diagram text uses the same fonts as the document body
• Publication Quality: Vector output at any resolution for print and PDF
• Editable Source: Modify graphic parameters directly in LaTeX source
• Version Control: Track diagram changes alongside document revisions
• No External Files: Self-contained document without separate image dependencies

Practical Examples

Example 1: Simple Diagram

Input SVG file (diagram.svg):

<svg xmlns="http://www.w3.org/2000/svg"
     width="200" height="100">
  <rect x="10" y="20" width="80" height="40"
        fill="none" stroke="black"/>
  <text x="50" y="45"
        text-anchor="middle">Input</text>
  <line x1="90" y1="40" x2="120" y2="40"
        stroke="black"/>
  <rect x="120" y="20" width="80" height="40"
        fill="none" stroke="black"/>
  <text x="160" y="45"
        text-anchor="middle">Output</text>
</svg>

Output LaTeX file (diagram.tex):

\begin{tikzpicture}
  \draw (0.1,0.6) rectangle (0.9,1.0);
  \node at (0.5,0.55) {Input};
  \draw (0.9,0.6) -- (1.2,0.6);
  \draw (1.2,0.6) rectangle (2.0,1.0);
  \node at (1.6,0.55) {Output};
\end{tikzpicture}

Example 2: Colored Shapes

Input SVG file (shapes.svg):

<svg xmlns="http://www.w3.org/2000/svg"
     width="200" height="100">
  <circle cx="50" cy="50" r="30"
          fill="#3498db"/>
  <rect x="120" y="20" width="60" height="60"
        fill="#e74c3c"/>
</svg>

Output LaTeX file (shapes.tex):

\begin{tikzpicture}
  \definecolor{svgblue}{HTML}{3498DB}
  \definecolor{svgred}{HTML}{E74C3C}
  \fill[svgblue] (0.5,0.5) circle (0.3);
  \fill[svgred] (1.2,0.2) rectangle (1.8,0.8);
\end{tikzpicture}

Example 3: Annotated Figure

Input SVG file (figure.svg):

<svg xmlns="http://www.w3.org/2000/svg"
     width="300" height="150">
  <title>System Architecture</title>
  <rect x="20" y="20" width="100" height="50"
        fill="#ecf0f1" stroke="#2c3e50"/>
  <text x="70" y="50"
        text-anchor="middle">Frontend</text>
  <rect x="180" y="20" width="100" height="50"
        fill="#ecf0f1" stroke="#2c3e50"/>
  <text x="230" y="50"
        text-anchor="middle">Backend</text>
  <text x="150" y="120"
        text-anchor="middle">REST API</text>
</svg>

Output LaTeX file (figure.tex):

% System Architecture
\begin{tikzpicture}
  \definecolor{bgfill}{HTML}{ECF0F1}
  \definecolor{bordercol}{HTML}{2C3E50}
  \draw[fill=bgfill, draw=bordercol]
    (0.2,0.67) rectangle (1.2,1.17);
  \node at (0.7,0.92) {Frontend};
  \draw[fill=bgfill, draw=bordercol]
    (1.8,0.67) rectangle (2.8,1.17);
  \node at (2.3,0.92) {Backend};
  \node at (1.5,0.2) {REST API};
\end{tikzpicture}

Frequently Asked Questions (FAQ)

Q: What is SVG format?

A: SVG (Scalable Vector Graphics) is an XML-based vector image format standardized by the W3C. It uses XML elements to define shapes, paths, text, and other graphical objects. SVG files are plain text, resolution-independent, and natively supported by all modern web browsers. They are commonly used for icons, logos, illustrations, and interactive web graphics.

Q: What LaTeX packages are needed for the output?

A: The converted output uses the TikZ package (\usepackage{tikz}), which is included in all standard LaTeX distributions (TeX Live, MiKTeX, MacTeX). For color support, the xcolor package may also be loaded. No additional or exotic packages are required.

Q: Are SVG gradients supported in TikZ output?

A: TikZ supports basic linear and radial gradients through shading commands. Simple SVG gradients are converted to equivalent TikZ shadings. Complex multi-stop gradients may be simplified, as TikZ shading syntax has some limitations compared to SVG gradient definitions.

Q: How are SVG colors mapped to LaTeX?

A: SVG hex color values (#RRGGBB) are converted to LaTeX color definitions using \definecolor with HTML color model. Named CSS colors are mapped to their hex equivalents. The xcolor package handles the color rendering in the compiled PDF output.

Q: Can I edit the TikZ code after conversion?

A: Yes, the generated TikZ code is clean, commented, and fully editable. You can modify coordinates, colors, line styles, text labels, and add mathematical annotations. This is one of the key advantages of native TikZ code over embedded image files.

Q: How are SVG transformations handled?

A: SVG transform attributes (translate, rotate, scale, matrix) are converted to equivalent TikZ transformation options. TikZ supports shift, rotate, scale, and arbitrary transformation matrices, so most SVG transformations can be accurately represented in the LaTeX output.

Q: Does the output work with Overleaf?

A: Yes, the generated LaTeX/TikZ code works perfectly in Overleaf and any other LaTeX editor. Simply paste the TikZ environment into your document or use \input to include it from a separate file. Overleaf has TikZ pre-installed in its TeX Live distribution.

Q: What happens to SVG text elements in LaTeX?

A: SVG text elements are converted to TikZ \node commands, which means the text is rendered by LaTeX using the document's font settings. This ensures typographic consistency between diagram labels and document body text, and you can even use LaTeX math mode in the text nodes.
