Nutrient.SDK package

Markdown version of this page, suitable for AI agents and automation

The Nutrient .NET SDK ships in two NuGet packages. Both process PDF, Office, and image documents, and one license key works with either — pick the one that fits your project.

Nutrient.SDK is the newer of the two: an idiomatic, document-centric C# API for current .NET. The guides in this section cover Nutrient.SDK only; the rest of the .NET SDK guides cover the GdPicture.API package.
