Emails—whether they contain contracts, official correspondence, or other vital data—frequently need to be archived or shared as immutable documents. Converting an email to PDF preserves its original layout, and custom page‑size options give you complete control over the final dimensions. In this tutorial we’ll demonstrate how to render email messages as PDFs in popular formats such as A4, A3, A2, A1, Letter, and more, using the Cloud Java SDK and the Java REST API. Let’s dive in, set up the environment, and start converting emails to PDF with precision and flexibility!

Steps to Render Emails to PDF with the Java REST API

1. Sign up and get your API credentials from the GroupDocs Cloud Dashboard
2. Download the GroupDocs.Viewer Cloud Java SDK and set up a Java project
3. Configure your API credentials with the Configuration class
4. Initialize the ViewApi class for rendering
5. Create a FileInfo class and set the source file path in cloud storage
6. Set the output file format as PDF with ViewOptions
7. Select A4 as the page size of the output PDF document
8. Finally, create and execute the Email to PDF rendering request

This simple yet powerful approach allows you to render and customize emails in PDF format without ever leaving your Java development environment. Developers can implement this capability as an integrated module into their Java document management solutions across Windows, Linux, and macOS platforms. This process is ideal for businesses that need to generate and archive emails in a globally accepted format, ensuring they are secure, non-editable, and accessible from any device.
