GroupDocs.Conversion for Python via .NET is a document conversion API that lets you easily convert the most popular file formats, including DOCX, XLSX, PPTX, PDF, CAD drawings, and many more. It preserves layout and formatting while offering customization options for each format.

Get Started

pip install groupdocs-conversion-net

from groupdocs.conversion import Converter
from groupdocs.conversion.options.convert import PdfConvertOptions

with Converter("document.docx") as converter:
    converter.convert("output.pdf", PdfConvertOptions())

How It Works

The package is a self-contained Python wheel (~200 MB) that includes everything needed to process documents. No external software installation is required - just pip install and start converting. The wheel works across Python 3.5 - 3.14 on Windows, Linux, and macOS (Intel + Apple Silicon).

Features

• Wide Format Support: Over 10,000 conversion pairs across Microsoft Office, PDF, HTML, images, CAD, and more.
• Flexible Options: Convert entire documents, specific pages, page ranges, or files within archives.
• Format Detection: Automatically detects input file format.
• No External Dependencies: No Microsoft Office or other software required.
• Cross-Platform: Windows x64/x86, Linux x64, macOS x64/ARM64.

Examples

Convert DOCX to PDF

from groupdocs.conversion import Converter
from groupdocs.conversion.options.convert import PdfConvertOptions

with Converter("./business-plan.docx") as converter:
    converter.convert("./business-plan.pdf", PdfConvertOptions())

Convert with Advanced Options

from groupdocs.conversion import Converter
from groupdocs.conversion.options.convert import PdfConvertOptions
from groupdocs.conversion.options.load import WordProcessingLoadOptions

load_options = WordProcessingLoadOptions()
load_options.password = "12345"

with Converter("./protected.docx", load_options) as converter:
    options = PdfConvertOptions()
    options.dpi = 300
    options.page_number = 1
    options.pages_count = 2
    converter.convert("./output.pdf", options)

Get Document Info

from groupdocs.conversion import Converter

with Converter("./document.pdf") as converter:
    info = converter.get_document_info()
    print(f"Pages: {info.pages_count}")

Convert from Stream / BytesIO

import io
from groupdocs.conversion import Converter
from groupdocs.conversion.options.convert import PdfConvertOptions

with open("document.docx", "rb") as stream:
    with Converter(stream) as converter:
        converter.convert("output.pdf", PdfConvertOptions())

buf = io.BytesIO(downloaded_bytes)
with Converter(buf) as converter:
    converter.convert("output.pdf", PdfConvertOptions())

AI Agent & LLM Friendly

This package is designed for seamless integration with AI agents, LLMs, and automated code generation tools.

• AGENTS.md in the package — AI coding assistants (Claude Code, Cursor, GitHub Copilot) auto-discover the API surface, usage patterns, and troubleshooting tips from the installed package
• MCP server — connect your AI tool to GroupDocs documentation for on-demand API lookups:

  { "mcpServers": { "groupdocs-docs": { "url": "https://docs.groupdocs.com/mcp" } } }
  

• Machine-readable docs — full documentation available as plain text for RAG and LLM context:
  • Single file: https://docs.groupdocs.com/conversion/python-net/llms-full.txt
  • Per page: append .md to any docs URL

Evaluation Mode

The API works without a license in evaluation mode with the following limitations:

• A watermark is added to output documents.
• Only the first 3 pages are processed.

To remove these limitations, apply a license or request a temporary license:

from groupdocs.conversion import License
License().set_license("path/to/license.lic")

Or set the environment variable (auto-applied at import):

export GROUPDOCS_LIC_PATH="path/to/license.lic"

Troubleshooting

Issue	Platform	Fix
System.Drawing.Common is not supported	Linux/macOS	apt-get install libgdiplus (Linux) or brew install mono-libgdiplus (macOS)
Garbled text or missing fonts in PDF	Linux	apt-get install ttf-mscorefonts-installer fontconfig && fc-cache -f
The type initializer for 'Gdip' threw an exception	macOS	brew install mono-libgdiplus
DOTNET_SYSTEM_GLOBALIZATION_INVARIANT errors	Linux	Do NOT set this variable. ICU must be available.

System Requirements

• Python 3.5 - 3.14
• Windows x64/x86, Linux x64, macOS x64/ARM64
