EPUB is a popular e‑book format prized for its cross‑device compatibility. If you ever need to merge EPUB files using Java—whether to assemble collections, join chapters, or personalize an e‑book—this tutorial shows you exactly how to combine EPUB files in Java. We’ll start by setting up your development environment with an IDE such as IntelliJ IDEA, then walk through the essential steps and provide a ready‑to‑run code example for the merging process.

Steps to Merge EPUB files using Java

1. Configure your Integrated Development Environment (IDE) to use GroupDocs.Merger for Java, enabling the merging of EPUB files
2. Instantiate the Merger class and provide the file path of the source EPUB file as a parameter to its constructor
3. Add additional EPUB files to the merging process using the Merger.Join method
4. Complete the merging operation by calling the Merger.Save method

One of the primary benefits of how to join EPUB files using Java is its flexibility and compatibility across multiple platforms. The outlined steps are designed to work effectively on popular operating systems such as Windows, macOS, and Linux. A significant advantage is that, besides Java, no extra software installations are needed. The typical process involves creating an instance of the Merger class, adding more EPUB files as required, and completing the merge by saving the combined EPUB file with a chosen filename. This functionality simplifies document management tasks and increases productivity, making it an essential tool for developers handling EPUB files.
