When you are working with PDF documents, differences between the two versions can sometimes be hard to spot. Whether you are handling contracts, reports, or technical documents, pinpointing the variations between files is critical for accuracy and decision-making. By automating the comparison process, you can save time and generate results efficiently; no more scrolling through page after page, manually highlighting differences.

In this article, we will walk you through using the Java REST API to compare PDF documents and easily detect changes, updates, or discrepancies between versions. Let’s get started!

Steps to Compare PDF Documents using Java REST API

1. Sign up and get your API credentials from the GroupDocs Cloud Dashboard
2. Download the GroupDocs.Comparison Cloud Java SDK and set up a Java project
3. Configure your API client ID and secret with the Configuration class
4. Create an instance of CompareApi
5. Set up the FileInfo objects for the source and target PDFs
6. Apply comparison options using the ComparisonOptions class
7. Create and process the PDF document comparison request

These steps enable you to automate PDF comparison with the Cloud Java SDK and integrate file comparison functionality into your cross-platform Java document management applications. You can save significant time and focus on more important tasks, experience high accuracy, and easily track changes between versions of a PDF document. With the Cloud REST API, you can compare documents from anywhere and any platform, as long as you have an internet connection.
