PDF is a common document that is used digitally everywhere. I have been involved in a few Vue projects that require PDF display. For simple viewing, native browser function or iframe solutions should suffice. For more advanced rendering and interactions, you will need dedicated libraries that offer features like theme customization, responsive layouts and reliable support.
Choosing a PDF viewer for a Vue.js application depends on your project’s needs. Here’s a quick breakdown of five options to consider:
- PDF.js (Open Source): Reliable, no-frills viewing for simple applications.
- vue-pdf (Open Source): Lightweight wrapper for PDF.js, built for Vue.
- Nutrient (Paid): Feature-rich and enterprise-ready, ideal for complex needs.
- Vue PDF Viewer (Paid): Customizable and powerful, built for Vue.
- PDF.js Express (Hybrid): Start with free basics, with optional premium add-ons.
In this article, I'll be comparing five popular PDF libraries for Vue.js. Each library has its strengths and weaknesses, and my goal is to help you pick the best one for your project’s unique needs.

Importance of a Reliable PDF Viewer
In any Vue.js application where document viewing is essential, a reliable PDF viewer can make all the difference. Whether you’re building a business dashboard, an educational platform, or a document management system, the right PDF viewer streamlines development and enhances the user experience.
Key Criteria for Choosing a PDF Viewer in Vue.js
When selecting a PDF viewer, a few critical factors can determine whether it will fit your project needs:
- Performance: Fast loading and smooth rendering, especially for large PDFs, are essential.
- Ease of Integration: Libraries that integrate easily into Vue projects save time and simplify maintenance.
- Customization: The ability to style, extend, and configure is important for aligning with specific requirements.
- Community & Support: Documentation and community resources make troubleshooting easier and enhance long-term viability.
With these in mind, let’s explore the top options!
Open Source PDF Viewers
1. PDF.js
PDF.js is a well-known open-source JavaScript library created by Mozilla for rendering PDFs directly in the browser. The library allows developers to display PDF documents without relying on external plugins or native applications. PDF.js renders PDFs by converting each page into HTML5 canvas elements, ensuring that the content is viewable directly in the browser.
Developers who need a simple, cost-effective solution for displaying PDFs in Vue applications often use PDF.js as a base library. Because it’s a standalone JavaScript library, it’s compatible across multiple frameworks. However, it’s not built specifically for Vue, so Vue developers may need to use wrappers or custom integration to make the most of it.
Strengths:
- Large, active community and extensive documentation.
- Free to use, with a simple API that allows basic PDF rendering.
- Actively maintained, so updates and support are consistent.
Limitations:
- Not specifically designed for Vue; additional setup or wrappers like vue-pdf may be required for integration.
- Limited customization, so advanced functionality (e.g., annotations) requires additional coding.
Best Suited For: Simple applications where basic PDF rendering is suffices. While customization is possible, integrating advanced features with Vue.js requires extensive effort as the library is not designed specifically for the framework.
2. vue-pdf
Vue-pdf is a lightweight wrapper around PDF.js, specifically tailored for Vue applications. While PDF.js itself provides a core PDF rendering engine, vue-pdf simplifies the integration process for Vue developers, making it easier to render PDFs without writing extensive code. By using vue-pdf, Vue developers can enjoy the benefits of PDF.js without needing to manage the complex JavaScript integration manually.
Vue-pdf is ideal for applications that require basic PDF display but don’t need extensive functionality like annotations or form filling. It’s popular in small projects and MVPs where ease of use and quick implementation are prioritized.
Strengths:
- Vue compatibility out-of-the-box, which simplifies integration.
- Free and open-source, with a straightforward API.
- Great for smaller projects and quick prototyping.
Limitations:
- Limited advanced features, so it’s best suited for basic viewing.
- Minimal control over rendering or layout; not ideal for highly customized projects.
Best Suited For: Lightweight applications with straightforward PDF display needs without default layout. Vue-pdf is widely used in the Vue.js community, but be aware that the library has not been updated in over 3 years, which may lead to potential security and compatibility concerns.
Paid PDF Viewers
3. Nutrient (formerly PSPDFKit)
Nutrient is a premium, enterprise-grade PDF SDK designed to meet the needs of complex applications with advanced PDF requirements. This SDK goes beyond basic PDF viewing, offering interactive features like annotations, form filling, and even document editing. Built with scalability and customization in mind, Nutrient is often chosen by large-scale applications that prioritize security, stability, and extensive functionality.
While Nutrient is not designed specifically for Vue, it can be integrated into Vue applications with some customization. It’s ideal for organizations that need robust PDF features and are willing to invest in a paid solution that comes with dedicated support and a rich feature set.

- Integration with Vue may require extensive customization and configuration.
Best Suited For: Enterprise applications that demand robust, feature-rich PDF functionality such as annotation and editing. Nutrient is ideal for large-scale projects where security, performance, and dedicated support are priorities. However, its high cost and the need for extensive Vue-specific customization may make it less suitable for smaller teams or simpler projects.
4. Vue PDF Viewer
Vue PDF Viewer is a Vue-native solution designed specifically for Vue.js applications. Unlike generic libraries, it integrates seamlessly with Vue projects, offering features that cater to both simple and complex PDF requirements. Its native compatibility ensures that developers can focus more on building their applications and less on managing integration challenges.
