React-pdf will get you PDF rendering fast, but for teams building production applications, the real question is what happens when your document requirements outgrow that lightweight foundation. This post lays out how react-pdf and Apryse WebViewer compare on the features that tend to surface as products mature: annotations, forms, redaction, signatures, and UI customization. With a quick-reference comparison table and a real migration story, it’s a practical read for anyone choosing a React PDF viewer with an eye on where their app is headed, not just where it is today.
Short Answer
If you need a basic PDF viewer in a React application, react-pdf (built on Mozilla PDF.js) is an excellent starting point.
If you need a viewer that can grow with your application — supporting advanced document workflows, extensive UI customization, annotations, redaction, signatures, and additional document formats — Apryse WebViewer is the stronger long-term choice.
The right decision depends less on whether a library is open source and more on how much functionality your application will eventually require.
Quick comparison
Which React PDF Viewer Is Most Adaptable?
If adaptability means the ability to customize your application’s document experience over time, Apryse WebViewer provides significantly more flexibility than many developers expect.
While react-pdf is open source, it intentionally provides a lightweight viewer. Development teams typically build their own toolbar, search experience, annotation interface, document workflows, and branding on top of it.
Apryse WebViewer approaches the problem differently. It includes a fully featured viewer while exposing a modular, themeable UI that developers can customize, extend, or replace without rebuilding core document functionality.
For many production teams, that means spending more time building product-specific features instead of document infrastructure.
The Hidden Cost of Starting Simple
Open-source libraries reduce licensing costs, but they do not eliminate engineering costs.
As applications mature, teams often need features such as:
- Search
- Annotation
- Document comparison
- Redaction
- Digital signatures
- Accessibility improvements
- Workflow customization
Each additional requirement increases the amount of custom code that must be maintained.
Many organizations eventually decide that maintaining document infrastructure is not where they want to invest engineering effort.
Real-World Example
Blue Voice initially built its application using an open-source React PDF viewer. As the product expanded across police departments, maintaining PDF functionality internally began consuming engineering time that could have been spent improving the company’s core product. The team ultimately adopted Apryse WebViewer, allowing developers to focus on customer-facing innovation instead of maintaining document infrastructure. They later expanded their application with AI-powered document workflows built on top of the same platform.
FAQ
Is react-pdf good enough for production?
Yes. For applications that only need reliable PDF rendering and basic viewing. Applications that require advanced workflows often find themselves implementing many features manually over time.
Is Apryse WebViewer customizable?
Yes. The UI is modular and themeable, allowing organizations to customize branding, layouts, workflows, and user experience without rebuilding a document viewer from scratch.
Which PDF viewer is better for enterprise applications?
For teams that expect document requirements to grow over time, Apryse WebViewer generally requires less custom infrastructure while providing a broader set of document capabilities.
