Setting Up GroupDocs.Conversion for Java

First, add the maven groupdocs dependency to your pom.xml. This snippet pulls the latest library from the official GroupDocs repository.

<repositories>
   <repository>
      <id>repository.groupdocs.com</id>
      <name>GroupDocs Repository</name>
      <url>https://releases.groupdocs.com/conversion/java/</url>
   </repository>
</repositories>
<dependencies>
   <dependency>
      <groupId>com.groupdocs</groupId>
      <artifactId>groupdocs-conversion</artifactId>
      <version>25.2</version>
   </dependency>
</dependencies>

License Acquisition

You can start with a Free Trial, request a Temporary License, or purchase a full commercial license. Whichever route you choose, make sure the license file is loaded before invoking any conversion methods.

// Import necessary classes from GroupDocs.Conversion package
import com.groupdocs.conversion.Converter;

Implementation Guide – Convert Protected Word to PDF

Below is a step‑by‑step walkthrough that covers loading a password‑protected DOCX, configuring conversion options, and writing the PDF output.

1. Load the Password‑Protected Document

Provide the password via WordProcessingLoadOptions so GroupDocs can open the file.

// Create an instance of WordProcessingLoadOptions and set the password
WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
loadOptions.setPassword("12345");

Why this matters: Without setting the password, the API would throw an InvalidPasswordException.

2. Initialize the Converter

Pass the document path and the load options to the Converter constructor.

// Path to the password-protected Word document
String documentPath = "YOUR_DOCUMENT_DIRECTORY/SAMPLE_DOCX_WITH_PASSWORD";

// Create Converter instance with document path and load options
Converter converter = new Converter(documentPath, () -> loadOptions);

3. Define PDF Conversion Options

You can customize page ranges, margins, or embed fonts. For a basic conversion, the default PdfConvertOptions works fine.

// Configure PdfConvertOptions to specify the output format
PdfConvertOptions options = new PdfConvertOptions();

4. Execute the Conversion

Specify the output location and run the conversion.

// Path for the output PDF file
String outputPath = "YOUR_OUTPUT_DIRECTORY/LoadPasswordProtectedDocument.pdf";

// Convert Word to PDF using the defined options
converter.convert(outputPath, options);

After the call completes, LoadPasswordProtectedDocument.pdf will contain the same content as the original DOCX, ready for distribution.

Common Issues and Solutions

IssueSolution
Incorrect passwordDouble‑check the password string; it is case‑sensitive.
Version conflictEnsure the groupdocs-conversion version matches other GroupDocs libraries you may be using.
Out‑of‑memory errors on large filesProcess documents in smaller batches or increase the JVM heap size (-Xmx2g).
Missing Maven repositoryVerify the repository URL in pom.xml is correct and reachable.

Frequently Asked Questions

Q: Can I convert documents that aren’t password‑protected?
A: Yes—simply omit the WordProcessingLoadOptions password configuration.

Q: Is there a way to add PDF‑level password protection after conversion?
A: Absolutely. After conversion, you can use GroupDocs PDF or another library to encrypt the resulting PDF.
