Unlock the hidden data inside PDFs—author names, creation dates, custom application tags, and more—information that can be just as vital as the visible text. For Java developers, extracting PDF metadata powers smarter, feature‑rich applications. In this tutorial you’ll learn how to extract metadata from PDF files in Java using a lightweight yet powerful Java REST API, enabling you to integrate PDF metadata extraction into your projects with minimal code and effortless setup.

Steps to Extract Metadata From PDF Using Java

1. Sign up and get your API credentials from the GroupDocs Cloud Dashboard
2. Download the GroupDocs.Metadata Cloud Java SDK and create a Java project
3. Configure your API credentials with the Configuration class
4. Initialize the MetadataApi class and specify the source file with FileInfo
