Nutrient’s Document Web Services (DWS) platform offers cloud-native APIs that support every stage of the document lifecycle — from rendering a single PDF in the browser, to high-volume processing and automation.
What is an OCR SDK and what does it enable?
An optical character recognition software development kit, or OCR SDK, provides developers with tools to extract text from scanned images, PDFs, or other visual formats. Nutrient’s OCR SDK supports printed and handwritten text, Unicode characters, and complex layouts — making it easy to turn static files into searchable, editable content.
What file types and platforms are supported?
OCR and data extraction capabilities are available across web, mobile (iOS, Android), desktop (.NET), and server environments (Document Engine). You can process more than 100 file types — including image formats (TIFF, JPG, PNG) and scanned PDFs — with consistent output across platforms.
Can Nutrient handle handwriting and zonal OCR?
Yes. Nutrient OCR supports handwritten text recognition and zonal OCR, enabling you to target specific regions of a document — perfect for processing forms, ID cards, and invoices.
How does Nutrient ensure accurate results on complex documents?
Our SDKs use advanced OCR engines, AI-driven preprocessing (deskewing, noise reduction, contrast balancing), and document layout analysis to maximize recognition accuracy — even on distorted or low-quality scans.
Which languages are supported?
Nutrient OCR supports more than 30 languages, including complex character sets like Arabic, Japanese, and Cyrillic. Language packs can be easily toggled based on your application’s needs.
What data extraction capabilities are included?
Nutrient supports structured extraction of key-value pairs, tables, and form fields — powered by heuristic models, AI classification, and layout-aware logic. You can export results as JSON or XML, or integrate directly into downstream workflows.
What’s the difference between OCR and AI Document Processing?
OCR converts images into machine-readable text. AI Document Processing goes a step further by using classification, layout detection, and optional LLMs to extract meaning from an entire document, and not just words on a page. It’s ideal for unstructured or high-volume workflows.
Can I automate document classification and extraction without templates?
Yes. With AI Document Processing, you can classify documents and extract data without needing rigid templates. It’s powered by ML models that adapt to diverse formats — perfect for onboarding large volumes of semi-structured files.
Is there a trial version of Nutrient OCR and extraction tools?
Yes. You can start a free trial with watermark-limited access to all OCR and extraction features. For enterprise demos or extended testing, contact Sales for a temporary license key.

FOR DEVELOPERS
Integrating data extraction capabilities into your applications can significantly enhance efficiency and accuracy in processing documents. This section will explore the essentials of data extraction SDKs to guide you through this integration.
A data extraction SDK (software development kit) is a collection of tools and APIs that enables developers to incorporate data extraction functionalities into their software applications. These functionalities allow for the automatic retrieval of specific data from various document formats, such as PDFs, images, and scanned files, converting unstructured data into structured, actionable information. This is particularly beneficial for applications requiring document processing, data analysis, or automation of data entry tasks.
When selecting the appropriate data extraction SDK, consider the following factors:
Various data extraction tools are available, each offering distinct features:
Choosing Nutrient’s data extraction SDK offers several advantages:
While other data extraction tools may offer basic functionalities, Nutrient’s data extraction SDK stands out with its advanced OCR capabilities, high performance, and focus on security. Its design prioritizes ease of use and seamless integration, making it a robust choice for applications aiming to enhance document processing and data accuracy.
