A PDF SDK (software development kit) is a collection of tools, libraries, and documentation that enables developers to integrate PDF functionality directly into their applications. With a PDF SDK, you can add features like viewing, editing, annotating, form filling, digital signing, and document conversion without building these capabilities from scratch.
Yes. Nutrient offers PDF SDKs for all major platforms — including Web (JavaScript), iOS, Android, React Native, Flutter, .NET, and Java. Our SDKs share a consistent API design across platforms, making it easier to maintain cross-platform applications with unified PDF functionality.
Nutrient SDKs support PDF as the primary format, along with images (PNG, JPEG, TIFF), Microsoft Office documents (Word, Excel, PowerPoint), and more through our conversion capabilities. We provide native integrations for popular frameworks like React, Vue, Angular, and Next.js, and support both client-side and server-side implementations.
Absolutely. Nutrient SDKs offer extensive customization options, including theming, custom toolbars, branded UI components, and the ability to build completely custom interfaces using our APIs. You can match your brand colors, fonts, and design patterns while maintaining full PDF functionality.
Yes. Security is a top priority. Our SDKs support encryption, password protection, digital signatures, and redaction, and they comply with standards like PDF/A and PDF/UA. We offer both client-side processing for sensitive documents and secure server-side options. Our solutions are used in highly regulated industries, including healthcare, finance, and government.
Nutrient uses advanced rendering engines optimized for each platform. Our Web SDK leverages WebAssembly for consistent rendering across all browsers, while native SDKs use platform-specific optimizations. This ensures accurate display of complex PDFs, including forms, annotations, embedded fonts, and special formatting — regardless of the viewing environment.
We provide comprehensive documentation, API references, integration guides, code samples, and video tutorials. Our GitHub repositories include example projects for various frameworks. You also get access to dedicated support channels, regular webinars, and a responsive technical support team to help with implementation.
A dedicated PDF SDK gives you complete control over the user experience, data security, and feature set. Unlike third-party viewers, you own the implementation, avoid vendor lock-in, and can customize every aspect. PDF SDKs also eliminate external dependencies, reduce latency, and ensure your sensitive documents never leave your infrastructure.
Getting started is easy: Sign up for a free trial, choose your platform, and follow our getting started guides. Most developers have a working PDF viewer in less than 15 minutes. Our SDKs include npm packages, CocoaPods, Maven repositories, and NuGet packages for easy integration. No credit card is required for the trial, and we offer flexible licensing options for production use.
