How to Convert Word to PDF in Java

Developers can convert Microsoft Word documents to PDF format effortlessly. This conversion process involves two main steps: first, converting the Word document to HTML, and then, using the generated HTML to create a PDF file with IronPDF Java. But why is this conversion necessary? Well, there are several reasons.

First, PDFs are widely regarded as the standard for document sharing, ensuring that the document's formatting remains consistent across different devices and platforms.

Code for convert HTML to PDF document

Imports: The necessary classes are imported from the IronPDF Java library.

    import com.ironsoftware.ironpdf.*;
    import java.nio.file.Paths;

License Key: Apply your IronPDF license key. Replace "YOUR-LICENSE-KEY" with your actual license key.


Set Log Path: Set a log path for the IronPDF engine. This is useful for debugging and monitoring purposes. In this code example, the log path is set to "C:/tmp/IronPdfEngine.log".


Render HTML as PDF: Create a PdfDocument object by rendering the HTML content of a file as a PDF. In this case, the HTML file is named "wordHTML.html". The PdfDocument object, myPdf, holds the converted PDF content.

    PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("wordHTML.html");

Save PDF: Save the PdfDocument object as a PDF document. In this example, the output PDF document is named "wordToPdf.pdf".


Let's have a look on complete code example:

    import com.ironsoftware.ironpdf.*;
    import java.nio.file.Paths;

    // Apply your license key

    // Set a log path

    // Render the HTML as a PDF. Stored in myPdf as type PdfDocument;
    PdfDocument myPdf = PdfDocument.renderHtmlFileAsPdf("example.html");

    // Save the PdfDocument to a file

To summarize, this code snippet shows the process of converting an HTML file to a PDF file using the IronPDF Java library. It first imports the necessary classes, sets up the license key and log path, and then renders the HTML file as a PDF document. Finally, the converted PDF is saved to a specified file path.
