Note

GroupDocs.Conversion for Python via .NET does not require any external software such as Microsoft Office or third-party document editors. To install the library, follow the steps in the Installation guide.

GroupDocs.Conversion for Python via .NET runs on Windows, Linux, and macOS. Choose the wheel that matches your platform — the package ships as a platform-specific .whl on PyPI and pip will pick the correct one automatically.

• Microsoft Windows 10 (x64)
• Microsoft Windows 11 (x64)
• Microsoft Windows Server 2016 and later

• Ubuntu 20.04+, Debian 11+, CentOS 8+, Fedora 36+ (glibc-based distributions)

• macOS 12 (Monterey) and later — Intel and Apple Silicon (M-series)

GroupDocs.Conversion for Python via .NET supports Python 3.5 through 3.14. The wheel uses the py3-none-{platform} tag, meaning it works with any Python 3.x version in that range without per-version rebuilds.

GroupDocs.Conversion for Python via .NET is distributed via PyPI:

pip install groupdocs-conversion-net

The PyPI index hosts one wheel per platform:

The wheel bundles its own .NET runtime and native rendering libraries, so there is nothing to install on Windows. On Linux you need fonts and ICU; on macOS, nothing.

Note

libgdiplus is no longer required. Releases up to 26.5 rendered through System.Drawing.Common, which needs a GDI+ implementation. From 26.9 (conversion engine 26.8 on .NET 10) the cross-platform build uses SkiaSharp and Aspose.Drawing instead, and the Linux and macOS wheels no longer contain System.Drawing.Common at all. You can remove libgdiplus / mono-libgdiplus from your images and provisioning scripts.

Install the following packages on Debian / Ubuntu derivatives:

sudo apt-get update
sudo apt-get install -y libicu-dev fontconfig ttf-mscorefonts-installer

• ttf-mscorefonts-installer — Microsoft core fonts (Arial, Times New Roman, …), which the engine looks up by name. These are required, not cosmetic: without them, converting an image to PDF fails with Cannot find any fonts installed on the system, and metric-compatible substitutes such as fonts-liberation alone are not enough. The package lives in Debian’s contrib component, which is not enabled on slim base images — add it first:

  sudo sed -i'.bak' 's/$/ contrib/' /etc/apt/sources.list
  sudo apt-get update
  

  Run sudo fc-cache -f afterwards so fontconfig picks the fonts up.

• fontconfig — font discovery and caching.

• ICU — required by the .NET runtime. On minimal distributions install it explicitly: sudo apt-get install -y libicu-dev. Do not set DOTNET_SYSTEM_GLOBALIZATION_INVARIANT, as it disables culture-sensitive conversions.

No extra packages are needed. macOS ships the fonts and rendering libraries the wheel relies on.

If you see a DllNotFoundException: libSkiaSharp error after upgrading, an older system copy of SkiaSharp is shadowing the one bundled with the wheel. Rename it so the bundled copy wins:

sudo mv /usr/local/lib/libSkiaSharp.dylib /usr/local/lib/libSkiaSharp.dylib.bak

No extra dependencies — the wheel is self-contained.
