What are the system requirements for integrating the PDF Viewer SDK into a web application?

A modern browser and web server are the only requirements to integrate PSPDFKit into a web application. There’s no dependency on frameworks such as React, Next, or Angular. For more information, refer to the PSPDFKit for Web browser support guide.

How does the PDF Viewer SDK ensure high-fidelity PDF rendering across different browsers and devices?

The PDF Viewer SDK has built-in mobile support for displaying your PDFs. It comes with a responsive UI that works on all screen sizes. The UI adapts to the screen automatically, providing you with a seamless experience. It provides the same features on desktop, tablet, and mobile views.

Can the PDF Web Viewer SDK enable customization to match our brand's UI/UX design?

PSPDFKit for Web makes it easy to customize every part of the user interface. Our robust API for configuring behavior and appearance lets you hide or add buttons, change the theme to match your look and feel, trigger workflows, create overlays, and much more.

What level of support and documentation is available for developers integrating the PDF Web Viewer SDK?

Documentation is available online in our guides and API Reference . These pages show you how to add document functionality to web apps. We also have a Knowledge Base and extensive samples available. Technical support is provided via our online portal .

How secure is the PDF Viewer SDK, and what security features are included?

The PSPDFKit SDK is based on an optimized fork of PDFium , the most trusted platform for PDF rendering. PDFium is the same PDF engine used in Chromium, Android, and countless other applications. The PDFium project is backed by Google, Microsoft, Amazon, and Dropbox . The PDF Web Viewer SDK is developed with a security-conscious approach. Encrypted PDFs are supported, and they cannot be accessed without the matching password. PDF passwords are never persisted, and code commits undergo peer review and extensive testing before being merged.

Is there a trial version of the PDF Web Viewer SDK available, and what are the limitations during the trial period?

The PDF Web Viewer SDK offers a flexible trial experience. You have the option to try our SDK with or without obtaining a trial key. The no trial key option is perfect for developers who want a quick look at all of the SDK’s capabilities. However, it’s important to note that this method comes with certain limitations: A red watermark will appear at the top of each page when viewing documents. If any alterations are made to a document, such as adding annotations, the red watermark will become a permanent fixture of the edited file. After running the app for one hour after a document is loaded, the viewer will show an alert. By obtaining a 30-day trial key , you’ll unlock the SDK’s full capabilities for 30 days without any of the aforementioned limitations.

How easy is it to integrate the PDF Web Viewer SDK with other tools and frameworks, such as React or Angular?

The Web Viewer SDK is compatible with any JavaScript framework, including React, Next, Angular, Vue, Svelte, Blazor, Solid, Nuxt.js, and jQuery. It’s also compatible with Electron, ASP.NET, PHP, Laravel, and Rails, as well as plain HTML5, JavaScript, and TypeScript.
