How to convert Word DOCX to PDF in Java

This tutorial will save you a ton of time with document conversion. Without any further ado, let’s get to the step-by-step.

Let’s set up our Repository and Dependency references in Maven:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

And…

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v2.32</version>
</dependency>
</dependencies>

Now we simply use the function convertDocumentDocToPdf:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.ConvertDocumentApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
ConvertDocumentApi apiInstance = new ConvertDocumentApi();
File inputFile = new File("/path/to/file"); // File | Input file to perform the operation on.
try {
    byte[] result = apiInstance.convertDocumentDocToPdf(inputFile);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling ConvertDocumentApi#convertDocumentDocToPdf");
    e.printStackTrace();
}

And that is absolutely all there is to it. We offer a range of related APIs, covering other document format conversions as well as editing, so be sure to check out the rest of our documentation for more information.
