Viewing PDF files directly within Node.js applications may require additional rendering layers. One effective way to simplify document handling is to display the PDF as a PNG, thus converting each PDF page into a lightweight image. It makes documents easier to preview in web apps, dashboards, and mobile platforms, while avoiding dependency on heavy PDF readers. Let’s explore how to render PDFs to PNGs in Node.js applications and build feature-rich Node.js PDF viewer tools using the cloud-based REST API.

Steps to Render PDF to PNG Using Node.js

1. Import and set up GroupDocs.Viewer Cloud Node.js SDK
2. Configure the API credentials and initialize ViewApi with them
3. Add the source PDF file with FileInfo
4. Define the viewing options using ViewOptions
5. Set up the PNG rendering options using ImageOptions
6. Create a PDF to PNG rendering request and process it with createView()

Instead of writing complex scripts or relying on third-party desktop converters, developers can follow these simple steps and view PDF files as PNGs using the Node.js REST API. Owing to extended browser and platform support, PNG images can be easily displayed in Node.js apps across Windows, Linux, and macOS. You can generate previews quickly with PNG files and embed image-based previewing capability into Node.js document management systems. Additionally, rendering individual pages and customizing output file size is also supported.

Code to Render PDF to PNG Using Node.js

Integrating PDF to PNG rendering in Node.js solutions unlocks new possibilities for document handling. You can rely on GroupDocs.Viewer Cloud Node.js SDK for this functionality. It helps you skip the complexity of handling PDF internals and focus on enhancing the user experience. With minimal coding effort, upgrade your apps with advanced PDF rendering options. Our Node.js REST API is a strong alternative to bulky libraries, offering a low-maintenance solution for viewing PDFs to PNGs.
