# C#.NET PDF library

Nutrient.NET SDK (formerly known as GdPicture.NET SDK) empowers your.NET applications with advanced OCR, data extraction, PDF editing, conversion, barcode reading and writing, TWAIN scanning, and more. It provides developers with a robust API to integrate PDF, imaging, and intelligent data processing capabilities quickly and efficiently.

Nutrient.NET SDK is organized in clear layers so you can build and scale document workflows without changing stacks:

- **App/UI layer** — Build with WinForms, WPF, MAUI, web/WASM hosts, or backend services.

- **SDK API layer** — Integrate through a consistent public API surface for document operations.

- **Document processing core** — Combine capabilities such as PDF processing, imaging, OCR and data extraction, barcode reading and writing, conversion, and viewing/annotation.

- **Platform targets** — Run across Windows, Linux, and macOS, with a separate WebAssembly (browser) target.

This layered approach helps teams start with standard use cases and expand into advanced processing scenarios over time.
