Nutrient .NET SDK

Server-side .NET library for advanced document processing — formerly distributed as GdPicture.NET SDK and consolidated under the Nutrient brand. Covers a broader capability set than typical Nutrient PDF SDKs: OCR, data extraction, PDF editing, conversion, barcode reading/writing, and TWAIN scanning.

Documentation

Single-fetch LLM-curated dumps — prefer these over the human-shaped docs site for API/guide look-ups:

• API reference: https://www.nutrient.io/api/gdpicture/llms.txt (the API dump is served under the legacy gdpicture path, not dotnet — see Heritage below)
• Guides: https://www.nutrient.io/guides/dotnet/llms.txt
• Cross-product index (other Nutrient SDKs): https://www.nutrient.io/llms.txt

Key Concepts

• Heritage: this product was previously sold as GdPicture.NET SDK. After the Nutrient rebrand, it ships under the Nutrient .NET SDK name — the same codebase, not a separate product line.
• vs MAUI: this is the server / desktop .NET SDK. For the mobile cross-platform .NET MAUI SDK, see nutrient-maui-sdk. Different products.
• vs Nutrient DWS: this is in-process. The hosted REST API alternative is the Nutrient DWS Processor API (covered by a separate plugin).
• vs other in-process languages: see nutrient-python-sdk, nutrient-nodejs-server-sdk, nutrient-java-server-sdk for the same in-process capability in those runtimes.
