Important Note: Starting from version 25.1.0, the GroupDocs.Conversion package has been split into two separate packages to better cater to different platforms.

The GroupDocs.Conversion package targets .NET 6 and later, offering cross-platform support for Windows, macOS, and Linux. This package is designed for modern .NET development, providing a streamlined and optimized experience.

For .NET Framework users, we have introduced the GroupDocs.Conversion.NETFramework package. It is specifically tailored for projects targeting .NET Framework 4.6.2 and above. This package ensures compatibility and includes all necessary libraries optimized for the .NET Framework runtime, with improved dependency resolution.

By splitting the package, we aim to provide a more flexible and efficient solution for both modern and legacy development environments. If you have any questions or need assistance, feel free to reach out via our free support forum.
