Nutrient Data Extraction API brings data extraction to PDFs, scans, and Office files, taking teams from document to structured, reviewable data with less manual review. AI/ML and data engineers use it to parse full document structure into Markdown or spatial JSON for RAG pipelines, search indexing, document Q&A, and knowledge bases. Backend and automation teams in finance, insurance, lending, legal, and healthcare use it to extract schema-defined fields from invoices, contracts, claims, forms, and statements. Bring your own JSON Schema to get conforming JSON with per-field confidence scores and source context, such as bounding boxes, so teams can validate values and route uncertain ones for review. Four processing modes (Text, Structure, Understand, and Agentic) combine OCR, ICR, computer vision, and VLM-enhanced ICR for born-digital files, scans, complex layouts, and handwriting. Credit-based per-page pricing avoids per-token fees.

Nutrient SDK brings real-time document collaboration inside your app: one document, every reviewer, live, without building sync infrastructure or routing files through a third-party collaboration tool. Developers, product managers, and UX engineers use it to add multi-user review to contract review, technical drawing markup, on-site field notes, and team approvals. Nutrient Instant, running with Document Engine over WebSockets, syncs annotations, comments, and form data across users and devices on web, iOS, and Android. Threaded comments pin to regions or annotations and can be resolved or reopened. Viewer, commenter, and editor roles are set with JWT-based permissions and can change mid-session. Document Engine can be self-hosted, so documents and collaboration data stay in your environment, and collaboration shares one document model with annotation, editing, and signing.

Nutrient SDK brings high-volume PDF generation into your app: data in, finished documents out, replacing hand-assembled documents and brittle scripts. Developers, operations teams, and business process owners use it to produce invoices, contracts, quotes, statements, and reports, from a single document in the browser to large batches for scheduled jobs and backend pipelines. Teams merge JSON data into DOCX templates with placeholders, repeating rows, nested loops, and conditional content, or render HTML and CSS into paginated PDFs, with output to PDF or Word. Generation runs client-side in the browser, server-side through Document Engine, or via a cloud API, so sensitive data can stay in the team's environment. SDKs cover JavaScript for the web, .NET, Java, and Python. Because output comes from the team's own templates, documents stay on-brand and consistent on every run, even when AI supplies the data.

Nutrient is the deterministic document platform organizations rely on to operationalize production capable agentic systems for document centric workflows. It combines reliable document processing infrastructure for agents, intelligent routing and governance, and interfaces for the human in the loop. Built on a decade of enterprise document expertise, Nutrient provides agentic document workflow solutions for thousands of organizations worldwide, including more than 15 percent of the Global 500, thousands of commercial businesses across 80 countries, and more than 130 public sector organizations in 24 countries.

Nutrient SDK delivers OCR for searchable PDFs and images, turning scans into selectable text and structured data rather than word soup. Developers, data engineers, and automation architects use it to index scanned records for search and compliance, digitize multilingual documents, and pull data from invoices, contracts, forms, and ID cards. OCR adds an embedded text layer while preserving the original layout, with PDF/A output for records management and accessibility. For structure beyond text, Data Extraction for Python and Java recognizes handwriting, equations, reading order, and tables with cell boundaries. The .NET SDK adds zonal OCR, image preprocessing such as deskew and noise removal, orientation detection, confidence scoring, and 100+ languages. OCR and extraction can run on your own infrastructure, and mobile SDKs process documents offline, keeping sensitive files in-house.

Nutrient SDK brings in-app PDF annotation and markup to document review, so users mark it up where it lives instead of exporting files to a separate review tool. Developers, product managers, and document review teams use it for contract and compliance review, board packs, blueprint and engineering markup, and approval workflows. It offers more than 15 spec-compliant annotation types, including highlights, underlines, strikeouts, ink, shapes, stamps, sticky notes, and free text, that render consistently across web, mobile, and desktop. Threaded comments attach to annotations, record author and time, and can be resolved or reopened, while permissions control who can view, comment on, or edit annotations. Teams can customize colors, toolbars, and stamps, query and manage annotations through the API, and export to XFDF for other PDF tools or Instant JSON for syncing across users and devices.

Nutrient DWS is a cloud platform of document APIs: Processor for headless document workflows (generation, conversion, OCR, redaction), Data Extraction for structured data from any document, AI Gateway for managed access to generative and decision models through flexible APIs, Viewer for embedding document viewing and review in your app, and Accessibility for PDF/UA tagging and validation — all without managing infrastructure.

Nutrient SDK brings PDF conversion into your app and pipelines: same document, different format, fidelity intact, without per-format libraries or a Microsoft Office installation. Developers, backend engineers, and document pipeline architects use it to turn contracts and reports into PDFs, export PDFs to editable Office files, convert images to PDF, and archive records as PDF/A. It converts Word, Excel, and PowerPoint to PDF, and PDF back to DOCX, XLSX, or PPTX, preserving layout, fonts, and tables. The Web SDK converts Office, TIFF, JPG, and PNG files client-side in the browser, so documents don't need to be uploaded, while Document Engine handles self-hosted, server-side batch conversion. The .NET SDK converts more than 100 file types to PDF, including HTML, email, and CAD. PDF/A output is designed to pass veraPDF validation for long-term retention.

Nutrient SDK brings PDF editing into your app, so users edit the document, not a copy of it, without a download-edit-reupload round-trip through a desktop editor. Developers and product managers use it to add in-app editing to contract, policy, proposal, compliance, and back-office workflows. The Content Editor lets users rewrite existing text, change font, size, and color, add or delete paragraphs, and resize or reposition text blocks, with fonts matched automatically and edits kept in the original file structure. The Document Editor handles page structure: reorder, rotate, delete, duplicate, insert, merge, and split pages through a thumbnail UI or in code, and page operations can run headless on a server for batch pipelines. Editing shares one API and document model with annotation, redaction, and signing, so a document can move from edit to redact to sign without leaving the application.

Nutrient SDK brings PDF generation to web, mobile, and server apps: data in, finished documents out, so teams stop assembling invoices, contracts, and statements by hand. Developers, operations teams, and business process owners use it to produce personalized documents on demand or in scheduled batches. DOCX templates support placeholders, repeating rows, nested loops, and conditional content filled from JSON data, with output to PDF or Word. Teams can also generate from PDF templates, images, or HTML and CSS, which Document Engine renders into paginated PDFs. AcroForm fields can be filled from JSON or XFDF and flattened for archiving, and pages from several files can be merged into one PDF. Generation runs client-side in the browser without a server, or headless on a server for automated pipelines. Because output comes from the team's own templates, documents stay on-brand and consistent on every run.

Integrate advanced document viewing, annotations, forms, signing, and editing into any JavaScript stack. Use the built-in UI, replace any component via the slot system, or run fully headless — every capability is reachable from code, ready for both human users and AI agents. Process client-side with WebAssembly, server-side, or in the cloud. Deliver pixel-perfect rendering with fast page streaming for large documents. Leverage 17+ annotation types, form creation and filling, plus electronic and digital signatures.

Nutrient SDK brings permanent PDF redaction into your app, so sensitive content is truly gone, not just hidden under a black box that can still be copied or searched. Developers, compliance officers, and legal teams use it to remove PII and confidential details from contracts, court documents, and board packs before sharing or archiving, supporting GDPR and HIPAA obligations. Applying redactions irreversibly deletes the text, images, and vector graphics in each marked region. Content can be marked manually or found with exact-text search, regular expressions, and built-in patterns for emails, phone numbers, and credit card numbers. A mark-then-apply workflow lets reviewers check every redaction before anything is removed, with customizable overlay text and fill colors. Redaction runs client-side in the Web and mobile SDKs, so files stay on the device, or through self-hosted Document Engine for headless and batch processing.

Nutrient PDF SDKs run consistently across all major platforms — Web (JavaScript/WebAssembly), iOS, Android, .NET, Java, Node.js, Flutter, and React Native — with native performance and unified APIs. Integrate document viewing, processing, and signing into your app with native and cross-platform SDKs. Explore features, tweak the UI, and export working code in seconds — with APIs that expose everything from prebuilt UI components to custom renderers, annotation hooks, and programmatic document operations.
