Protect your PDFs from unauthorized use with a single line of Java code. Adding an image watermark gives you a visual identifier that deters copying and reinforces branding across all documents.
In this tutorial we walk through five simple steps to embed an image watermark using the GroupDocs Watermark Cloud SDK for Java. You’ll see a complete, runnable code sample, learn how to configure opacity, scale, alignment, and margins, and even discover the equivalent cURL REST calls for server‑less integration.
By the end you’ll know how to install and configure the SDK, fine‑tune watermark options, and call the cloud API directly from your Java application. Whether you’re protecting contracts, e‑books, or marketing collateral, the guide gives you everything you need to get started quickly.
