NODEJS PDF SDK

Node.js PDF SDK for creation, editing, annotation, and conversion

Generate, edit, merge, annotate, and convert PDFs — including Office documents and images — directly in your Node.js backend with a TypeScript-friendly SDK that ships as a single npm package and never leaks your documents.

GET STARTED NOW GUIDES

Simplify development

Install one package — npm i @nutrient/node. One TypeScript API generates, edits, and converts PDFs from Office files, images, and HTML while running in-process. No context switching or external calls.

Accelerate time to market

Drop the battle-tested SDK straight into your CI/CD and storage flows. Built-in methods seal PDFs, restrict printing, and add passwords — no glue scripts.

Optimize performance

Offload CPU-heavy jobs to Node.js worker threads. The SDK trims file size, linearizes PDFs, and starts streaming pages sooner, keeping the event loop responsive under peak load.

COMPONENTS

Modular building blocks that grow with you

Start with today’s PDF tasks, and add more as you go. New components drop into the same npm package, powered by a lean TypeScript API that stays inside your Node.js process. Move from conversion to editing, annotation diffing, or form filling without rewriting code or sending data offsite.

Content editing

Programmatically modify, move, and resize text blocks while preserving fonts, styles, and layout — all inside your Node.js process.

Guides
Image documents

Turn JPG, PNG, and multipage TIFF files into PDFs, or render any PDF page back to PNG or WebP — no external services required.

Guides
Office files

Convert Word, Excel, and PowerPoint documents to pixel-perfect PDFs without requiring Microsoft Office or adding extra binaries.

Guides
Annotations

Create, import, diff, and flatten notes, highlights, shapes, stamps, and more using the same library that powers our Web and mobile SDKs.

Guides
Form filling

Fill out PDF forms programmatically with Instant JSON — text fields, checkboxes, and more — all handled natively in your Node.js process. No manual typing, no external services.

Guides
Document editing

Rotate, merge, split, crop, or add pages with a single API call. Nutrient Node.js SDK lets you edit PDFs on the fly — no third-party dependencies, just fast, reliable document operations inside your application.

OPERATOR NODES

Bridge Web Viewer SDK to Node.js

Run familiar JavaScript PDF calls on the server through the same WebAssembly core that powers our Web Viewer SDK. Stay in TypeScript, skip native installs, and ship features faster. Need HTML-to-PDF conversion, OCR, or other headless-browser jobs? Pair the Node.js SDK with Document Engine.

Node.js PDF SDKs: What are the advantages?

What is a Node.js PDF SDK?

A Node.js PDF SDK (software development kit) is a collection of tools and libraries that enables developers to incorporate PDF processing capabilities into Node.js applications. This includes functionalities such as creating, modifying, and optimizing PDF documents directly from the server side, facilitating seamless document management within your applications.

  • Lets users view, annotate, and edit PDFs right inside your app.
  • Simplifies document tasks like merging, splitting, or password-protecting PDFs.
  • Saves development time with prebuilt, reliable PDF components.
  • Ensures a consistent, high-fidelity viewing experience across devices.
How to choose the right Node.js PDF SDK

Selecting the appropriate Node.js PDF SDK is akin to choosing the right tool for a job — it should align perfectly with your project’s requirements. Consider the following factors:

  • Feature set — Ensure the SDK supports essential functionalities like PDF creation, editing, annotation, and conversion.
  • Performance — Look for an SDK optimized for efficient processing, especially if your application handles large documents or requires batch processing.
  • Ease of integration — A well-documented API with clear examples can significantly reduce development time.
  • Cross-platform support — If your application needs to operate across different environments, verify that the SDK offers cross-platform compatibility.
  • Licensing and cost — Assess whether the SDK’s licensing model aligns with your project’s budget and distribution plans.
What are the best solutions to solve my Node.js PDF integration needs?

Various PDF toolkits are available, each with its own strengths. The optimal solution depends on your specific use case:

  • Basic viewing needs — For applications requiring only PDF viewing capabilities, lightweight SDKs may suffice.
  • Advanced editing and annotation — If your project demands functionalities like editing, annotation, and encryption, a more comprehensive SDK such as Nutrient is advisable.
  • Niche specialty SDKs — Some SDKs excel at specific tasks like optical character recognition (OCR) but might lack other core functions.
What are the benefits of using a Node.js PDF SDK with Nutrient?

Opting for Nutrient (formerly PSPDFKit) offers several advantages:

  • Comprehensive feature set — Beyond basic PDF viewing and editing, Nutrient provides advanced functionalities such as digital signatures, form handling, and document optimization.
  • Server-side rendering — Optimized for backend processing, allowing efficient manipulation of PDFs within server environments.
  • High performance — Designed to handle high-volume document processing tasks, ensuring reliability and efficiency for enterprise-level applications.
  • Ease of integration — With well-documented guides and support, integrating Nutrient’s SDK into your Node.js application is straightforward.
  • Reliable support — Access to dedicated customer support and comprehensive documentation aids in smooth development and issue resolution.
How does Nutrient’s Node.js PDF SDK compare to open source alternatives?

While open source options offer basic PDF manipulation capabilities, they may lack advanced features and dedicated support. Nutrient’s SDK provides a more extensive feature set, regular updates, and professional support, which can be crucial for enterprise-level applications requiring reliability and scalability. Integrating PDF functionality into your Node.js application is a significant endeavor. By carefully evaluating your needs and exploring available options, you can select an SDK that not only meets your current requirements but also supports your application’s growth and evolution.
