Nutrient Document Web Services (DWS) help you build faster, scale smarter, and move past infrastructure friction with AI-powered Viewer and Processor APIs built for today’s developers.
Nutrient's Document Web Services (DWS) is a cloud-native platform that helps developers and product teams handle every part of the document lifecycle — from rendering a simple PDF in the browser, to running complex document processing.
Deliver rich document interactions directly in the browser — render PDFs, annotate, fill forms, and collect signatures with a cloud-hosted viewer API.
Handle advanced, headless document workflows from the cloud — generate, convert, extract, automate, and more with a processing API built for scale.
Automate PDF accessibility with cloud-based auto-tagging and validation that help you generate compliant, inclusive documents faster.
Viewer
Offload rendering and document intelligence to the cloud without standing up or maintaining backend infrastructure.
Add rendering, OCR, Office conversion, and PDF generation to your app — without setting up servers or managing infrastructure.
Stream rendering and processing from the cloud for faster load times and smoother UX.
Keep documents in the cloud — never on local devices — to reduce data exposure and simplify compliance.
Support real-time interaction with shared annotations, form inputs, and signatures.
Processor
Integrate document conversion, extraction, redaction, and automation directly into your server-side workflows.
Convert HTML, Office files, or Markdown into polished PDFs — no rendering engine or server setup required.
Whether you're running serverless, on Docker, in queues, or on a no-code platform, integration is straightforward and language-agnostic.
Offload compute-heavy document processing to our cloud platform — built to handle spikes, batches, and volume effortlessly.
Orchestrate flows like OCR → table extraction → PDF merge, all using lightweight, composable endpoints.
Accessibility
Automate PDF accessibility with cloud-based auto-tagging and validation APIs that help you generate inclusive, compliant documents faster.
Generate structured, tagged PDFs that improve screen reader compatibility and document navigation.
Run automated accessibility checks through repeatable API-driven pipelines to catch issues before documents are released.
Process accessibility workloads in the cloud while keeping operations centralized and predictable.
One intelligence across SDKs, cloud, low‑code, and workflows. The same document‑tuned AI engine powers every Nutrient product, adding real insight, automation, and compliance in a single drop‑in.
Summaries, smart diffs, and chat answers in seconds.
Confidence‑scored redaction with full audit trails.
Prompt‑based data capture, no templates.
No-code workflows route documents and data wherever they're needed.
Self-host, run on Nutrient-managed infrastructure, or use our cloud service — same AI engine, same results.

Nutrient Document Web Services (DWS) is a cloud-native platform that provides two powerful PDF API services: the Viewer API for browser-based document interactions and the Processor API for headless document workflow processing. Our PDF tools API enables developers to view, annotate, edit, generate, convert, and process documents without managing any infrastructure.
The Viewer API is our PDF viewer API for embedding interactive document viewing, annotation, form filling, and signing capabilities directly into web applications. It provides real-time collaboration and client-side rendering. The Processor API is our PDF processing API designed for backend workflows—document generation, conversion, OCR, data extraction, watermarking, and batch processing. Many developers use both APIs together for complete document workflows.
Our API services support a wide range of formats including PDF documents (.pdf), image files (.png, .jpg, .tiff, .webp), and Microsoft Office files (.doc, .docx, .ppt, .pptx, .xls, .xlsx). You can convert between formats, generate PDFs from HTML, and process documents in all these formats through our unified API.
No infrastructure setup required! Both Viewer API and Processor API are fully cloud-hosted and managed. You simply integrate our API with a few lines of code, and we handle all the scaling, security, updates, and maintenance. This lets you focus on building your application instead of managing document processing infrastructure.
Security is built into every layer of our API services. We're SOC 2 Type II certified and GDPR compliant. All data is encrypted in transit (HTTPS) and at rest. We provide configurable access tokens, support for password-protected documents, and digital signatures. Learn more about our security practices.
Absolutely. Our cloud infrastructure automatically scales to handle your workload, from a few documents per day to millions per month. Fortune 500 companies rely on our API for mission-critical applications. You can start on the free tier, upgrade as you grow, and we offer custom enterprise plans for high-volume needs.
Our API services are language-agnostic and work with any framework capable of making HTTP requests. The APIs integrate seamlessly with React, Angular, Vue, Next.js, Node.js, Django, Flask, Spring Boot, .NET, and more. We also offer no-code integration through Zapier.
All paid plans include technical support from our expert team. You'll have access to comprehensive documentation, integration guides, code examples, and our Discord community. Enterprise customers receive priority support with guaranteed response times. We're here to help you succeed with our PDF tools API.
Yes! Our Processor API includes AI-powered features like document understanding, key-value extraction, and automated redaction. We also offer the Nutrient DWS MCP Server for seamless integration with Large Language Models (LLMs) like Claude, enabling you to create, edit, and process documents using natural language. This makes it easy to build AI-powered document workflows.
