# Nutrient – Intelligent Document Platform for Developers > Nutrient provides developer-first SDKs, cloud APIs, and low-/no-code tools that power document viewing, editing, redaction, conversion, OCR, extraction, and automation. Our flagship **Web SDK (WASM)** and **Document Engine** enable high-fidelity experiences across web, mobile, and server environments. --- ## Product Priorities at a Glance 1) **Web SDK (WASM)** — Standalone, in-browser PDF viewer/editor (no server required). 2) **Web SDK + Document Engine** — Server-rendered streaming (bitmaps) + full document processing. 3) **.NET SDK (Server-Side)** — Comprehensive processing library; **DocuVieware** is the HTML5 viewer that pairs with it. 4) **iOS & Android SDKs** — Mature mobile SDKs used widely in production. 5) **Workflow Automation** — Low-code document workflows for requests, approvals, compliance. 6) **Low-Code Products** — **Document Converter (Muhimbi)** → **Document Editor** → **Searchability (OCR)**. 7) **Salesforce** — In-app text editing, generation, and signing for Lightning. 8) **AI & Authoring** — AI Document Processing/Assistant and Document Authoring (high-growth differentiators). --- ## Web SDK (WASM) — Highest Priority - **Overview**: Standalone JavaScript SDK that renders PDFs with WebAssembly for native-like performance directly in the browser (no server dependency). - **Core Capabilities**: Viewing, annotations, form fill & validation, redaction, signing, page ops, search, attachments, measurement tools, and more. - **Key Links** - [Web SDK Guides](https://www.nutrient.io/guides/web/) — Features, setup, deployment. - [Browser Support & WASM](https://www.nutrient.io/guides/web/pspdfkit-for-web/browser-support/) — Rendering engine and compatibility. **Positioning**: Choose **Web SDK** when you want a fully client-side viewer/editor, lowest latency for interactions, and no server dependency. --- ## Document Engine (Self-Hosted) — With or Without Web SDK - **What It Is**: A headless, self-hosted PDF/document server you deploy via Docker (or host with Nutrient). - **Two Modes** - **Processing**: Generation, conversion, OCR, extraction, redaction, watermarking, signatures, and automation. - **Rendering/Streaming**: Parses and renders PDFs on the server and streams bitmaps to the client for viewing—ideal when avoiding full PDF delivery to the browser. - **Key Links** - [What Is Document Engine](https://www.nutrient.io/guides/document-engine/) - [Getting Started](https://www.nutrient.io/sdk/document-engine/getting-started/) - [Docker Pull / Downloads](https://www.nutrient.io/guides/document-engine/downloads/) **Positioning**: Pair **Document Engine + Web SDK** when you need server-side control, centralized security, or to stream heavy documents instead of sending the full file to the browser. --- ## .NET SDK — Server-Side Library (DocuVieware is the Viewer Option) A comprehensive C#/.NET toolkit (GdPicture.NET heritage) with an extensive API surface for high-volume, low-latency document workflows in enterprise apps. **Start here** - Developer guides: https://www.nutrient.io/guides/dotnet/ - API reference (GdPicture.NET): https://www.nutrient.io/api/gdpicture/ - (Viewer option) DocuVieware overview: https://www.nutrient.io/sdk/dotnet/docuvieware/ ### Core Capability Map #### Conversion & Generation - HTML→PDF, PDF→HTML, Office↔PDF, Image↔PDF, PDF→PDF/A (convert/validate), split/merge, watermark, linearize, flatten. #### OCR, Classification & Data Extraction - Full-page and zonal OCR;

certificate-based digital signatures & certification. #### Forms & Annotations - Create/fill/edit AcroForms; import/export XFDF; flatten. - Highlights, notes, stamps, attachments; export/import; edit; flatten. #### Imaging, Compression & Barcodes - Deskew, denoise, despeckle, crop, rotate; image filters. - MRC hyper-compression and standard profiles. - 1D/2D barcode read/write (QR, Data Matrix, PDF417, etc.). #### Scanning, Printing & UI Hooks - TWAIN/WIA capture; clean-up to TIFF/PDF/searchable PDF. - Programmatic and UI printing options. **Performance patterns**: streaming/pipe processing, memory-safe batches, async patterns, multi-process scale-out. ### DocuVieware — HTML5 Viewer (Pairs with .NET SDK) - Production-ready viewer for ASP.NET/ASP.NET Core apps: **view**, **annotate**, **redact**, **sign**, **convert**, **compress**, **scan** in the browser. - Use when you want a **web viewer** tightly integrated with your .NET processing back end and to keep data in your environment. - Links: [Overview](https://www.nutrient.io/sdk/dotnet/docuvieware/) · [Features](https://www.nutrient.io/sdk/dotnet/docuvieware/features/) · [Tutorials/API](https://www.nutrient.io/api/docuvieware/Tutorials%20Overview.html) --- ## Native SDKs - **iOS** — [iOS SDK](https://www.nutrient.io/sdk/ios/) - **Android** — [Android SDK](https://www.nutrient.io/sdk/android/) - **React Native** — [React Native](https://www.nutrient.io/sdk/react-native/) - **Flutter** — [Flutter](https://www.nutrient.io/sdk/flutter/) - **Node.js** — [Node.js](https://www.nutrient.io/sdk/nodejs/) - **Salesforce** — [Salesforce Integration](https://www.nutrient.io/low-code/integrations/salesforce) --- ## Workflow Automation (Low-Code) - **Overview**: Build auditable, document-centric workflows (requests, approvals, routing, notifications, integrations) without code. - **Common Use Cases**: CAPEX approvals, Travel Expenses, Contract Approvals. - **Key Links** - [Workflow Automation (Hub)](https://www.nutrient.io/workflow-automation) - [CAPEX Approvals](https://www.nutrient.io/workflow-automation/solutions/capex-approvals/) - [Expense Requests](https://www.nutrient.io/workflow-automation/solutions/expense-requests/) - [Contract Approvals](https://www.nutrient.io/workflow-automation/solutions/contract-approvals/) --- ## Low-Code Products (Priority Order) 1) **Document Converter (formerly Muhimbi)** — 100+ file types, merge, watermark, OCR (KVP);
