Portable Document Format (PDF) files are among the most popular formats for sharing business documents. Converting a PDF to PNG is valuable because it creates high‑quality PNG images that can be embedded directly in browsers, mobile apps, or document viewers without the need for a specialized PDF reader. In this tutorial, we’ll demonstrate how to render PDF to PNG in Java apps using the Java REST API with flexible rendering options.

Steps to Render PDF to PNG Using Java

1. Download the GroupDocs.Viewer Cloud Java SDK and set up a Java project
2. Obtain and configure your API credentials with the Configuration class
3. Initialize the ViewApi class for rendering PDF
4. Use a FileInfo object to set the source file path in cloud storage
5. Apply ViewOptions and set the output format to PNG
6. Add the PNG rendering options using ImageOptions
7. Create a PDF to PNG rendering request and execute it with createView()

The above steps simplify the process of PDF to PNG rendering using the Cloud REST API. PNG images can be displayed on virtually any device, OS, or browser, allowing developers to create lightweight Java PDF viewer applications that render content quickly. Sharing the output PNG images prevents users from easily copying or extracting embedded data. You can achieve optimized performance using the Cloud API, as PNG rendering is faster than rendering full PDF documents, all with minimal code integration and no third-party dependencies.
