How to Convert LaTeX to DOCX

Why convert LaTeX to Word?

LaTeX produces beautifully typeset documents, but the academic and professional world does not run exclusively on LaTeX. Many journals, conferences, and publishers require manuscript submissions in Microsoft Word format. Springer, Elsevier, and Wiley all accept DOCX uploads, and some mandate it for the final camera-ready version. If you have spent months writing a paper in LaTeX, the last thing you want is to manually reformat it in Word. An automated converter preserves your equations, tables, citations, and section structure while producing a clean DOCX file that meets submission requirements.

Collaboration is another major reason. Not every co-author, reviewer, or supervisor is comfortable with LaTeX. Sending a DOCX file lets them use tracked changes and comments in Word or Google Docs, which is often the fastest feedback loop available. You can convert your LaTeX source to DOCX, collect comments, and apply the changes back to your original LaTeX file. This hybrid workflow is surprisingly common in interdisciplinary teams where some members work in LaTeX and others in Word.

Accessibility is a third consideration that is often overlooked. PDF files generated by LaTeX are not always screen-reader friendly. DOCX files, on the other hand, carry semantic structure that assistive technologies can parse more reliably. Converting to DOCX can be an intermediate step toward producing accessible documents, especially for institutions that must comply with accessibility standards like WCAG or Section 508. The conversion also makes it easier to extract plain text for translation services, plagiarism checkers, and language models that work better with structured document formats than with raw LaTeX markup.

Step-by-step: Convert with FormaTeX

The FormaTeX LaTeX to DOCX tool runs entirely in the browser. You paste your LaTeX source, upload any companion files, and download the result. No account is required, and the tool is free to use. Here is how it works, step by step.

Using the API for batch conversion

The browser-based tool is ideal for one-off conversions, but if you need to convert dozens or hundreds of LaTeX files, the FormaTeX REST API is a much better fit. The API accepts a LaTeX file upload and a target format parameter, then returns the converted document as a binary response. You can call it from any language that supports HTTP requests.

To get started, create an account on FormaTeX and generate an API key from your dashboard. The API key is shown once on creation and stored as a SHA-256 hash on the server, so save it in a secure location like an environment variable or a secrets manager. Include the key in the Authorization header of every request.

Below are two examples: a minimal cURL command for quick terminal-based conversion, and a Python script that converts every .tex file in a directory. Both examples use the same API endpoint and produce identical results.

curl -X POST https://api.formatex.io/api/v1/convert \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]" \
  -F "format=docx" \
  -F "engine=pdflatex" \
  -o thesis.docx

The cURL command sends a multipart form request with the LaTeX file, the target format (docx), and the compilation engine. The server compiles the document, converts it, and streams the DOCX binary back. The -o flag saves the output to a file.

import requests
import os
from pathlib import Path

API_KEY = os.environ["FORMATEX_API_KEY"]
BASE_URL = "https://api.formatex.io/api/v1"

def convert_latex_to_docx(
    tex_path: str,
    output_path: str,
    engine: str = "pdflatex",
) -> None:
    """Convert a .tex file to .docx using the FormaTeX API."""
    with open(tex_path, "rb") as f:
        response = requests.post(
            f"{BASE_URL}/convert",
            headers={"Authorization": f"Bearer {API_KEY}"},
            files={"file": (Path(tex_path).name, f, "text/x-tex")},
            data={"format": "docx", "engine": engine},
            timeout=60,
        )
    response.raise_for_status()
    with open(output_path, "wb") as out:
        out.write(response.content)
    print(f"Saved {output_path} ({len(response.content)} bytes)")


# Convert a single file
convert_latex_to_docx("paper.tex", "paper.docx")

# Batch convert every .tex file in a directory
for tex_file in Path("papers/").glob("*.tex"):
    docx_file = tex_file.with_suffix(".docx")
    convert_latex_to_docx(str(tex_file), str(docx_file))
    print(f"Converted {tex_file.name} -> {docx_file.name}")

The Python script defines a reusable convert_latex_to_docx function that handles file upload, error checking, and output saving. The batch loop at the bottom iterates over every .tex file in a directory and converts each one. You can extend this pattern to integrate with CI/CD pipelines, scheduled jobs, or document management systems.

Rate limits and compilation quotas depend on your plan. The free tier includes a generous number of conversions per month. For high-volume batch processing, consider the Pro or Team plans which offer higher rate limits and priority queue access. See the Python API guide for more examples, including async conversion with httpx and detailed error handling.

Advanced tips for better conversion results

The converter handles most LaTeX documents out of the box, but there are several things you can do to improve the quality of the output. These tips apply whether you use the browser tool or the API.
