When working with various types of documentation, there are often scenarios where content is spread across multiple Word files and sometimes even includes other document formats. Rather than sending them individually, merging them into one PDF not only looks professional but also makes it easier for recipients to navigate through the content. With Conholdate.Total for Java SDK, this process becomes highly efficient, enabling developers to combine two or more DOCX files, along with PDF files, into a single PDF file in just a few lines of code. Additionally, the merging capabilities extend beyond simple combination, allowing for advanced operations like merging selective pages, controlling the order of documents, and combining files of different formats in one go.

Combine Word Documents to PDF - Java SDK Configuration

You can easily render a single or multiple MSG files to PDF format using Conholdate.Total for Java. Simply download the JDK file from the Downloads section or paste the following Maven configurations in the pom.xml file of your application:

<dependency>
<groupId>com.conholdate</groupId>
<artifactId>conholdate-total</artifactId>
<version>25.4</version>
<type>pom</type>
</dependency>

Why Merge DOCX to PDF in Java?

  • Unified File Management: Combining multiple DOCX files into a single PDF creates a cleaner, more manageable file structure, eliminating the need to keep track of multiple documents.

  • Consistent Formatting: PDF preserves the original formatting of the DOCX files, ensuring that fonts, layouts, and images remain exactly as intended, regardless of the viewing platform.

  • Multi-Format Compatibility: You can merge DOCX with other formats like PDF, Excel, and PowerPoint into a single file for comprehensive document integration.

  • Selective Page Merging: Apart from combining whole documents, it is possible to merge only specific pages from each file, giving flexibility for custom document assembly.

Merge DOCX to PDF in Java

With Conholdate.Total for Java, you are able to merge two or more word documents or PDF documents into a single document. Following is a code snippet showing how to meet such requirements:

// Combine two or more DOCX and PDF files into one
Merger merger = new Merger("pdf_document.pdf");
{
merger.join("word_document.docx");

merger.save("merged-document.pdf");
}

This minimal example demonstrates the core flow for combining documents: create a Merger instance, join an additional document to that Merger, and then save the resulting combined PDF to disk. Use this pattern when you want a straightforward programmatic merge of an existing PDF plus one or more DOCX files into a single output PDF. The snippet is intentionally concise to show the key calls clearly, and it is well suited as the base of more advanced merging logic such as looping through a list of files to join, adding files conditionally, or performing pre-merge transformations on individual inputs.

Summing Up

Merging DOCX to PDF in Java is a practical and widely useful capability for many business processes, and the provided snippet shows the minimal, clear sequence to accomplish a merge with Conholdate.Total for Java SDK. You can build a reliable merging service that produces consistent, high fidelity PDF outputs for your applications.
