Easily Convert Markdown to Word and PDF in Java [Quick & Simple]

Markdown is a popular choice for creating and editing plain text documents thanks to its simplicity and ease of use. However, when you need a more polished presentation—like for professional reports or printable offline copies—it’s often necessary to convert Markdown files into more structured formats.

By converting Markdown to Word or PDF, you can apply richer formatting, ensure cross-platform compatibility, and produce documents that look professional. In this guide, we’ll walk through a simple way to convert Markdown to Word and PDF in Java, including how to batch process multiple files with minimal code.

Convert Markdown to Word in Java in 3 Steps

Compared to Markdown files, Word documents are more widely used and generally considered more formal. They’re easier to open and share, making them the preferred choice for official documents such as contracts or reports. Converting Markdown to Word in Java is straightforward — it basically involves three steps: creating a new document object, loading the Markdown file, and saving it as a Word document. Below, you’ll find a real code example demonstrating this process.

To make this task quick and simple, I’m using Spire.Doc for Java in this article.

Code example — converting a Markdown document to a Word document:

import com.spire.doc.Document;
import com.spire.doc.FileFormat;

public class MarkdownToWord {
   public static void main(String[] args) {
       // Create a Document instance
       Document doc = new Document();

       // Load a Markdown file
       doc.loadFromFile("/input/sample.md", FileFormat.Markdown);

       // Save the Markdown file as a Word document
       doc.saveToFile("/output/MarkdowntoWord.docx", FileFormat.Docx);
       doc.dispose();
   }
}

Keep in mind that some Markdown files include images represented by URLs. If you want the exported Word document to retain those images, additional steps are required.

Convert Markdown to PDF in Java without Effort

Sometimes, we also need to convert Markdown files to PDF, especially for documents intended for printing or sharing. PDF preserves the original layout well and is less likely to get corrupted during transfer. Converting to PDF in Java is just as easy as converting to Word — the only difference is setting the output format to PDF, while the rest of the steps remain the same. Here’s a sample code snippet for your reference.

Code example - converting a Markdown document to a PDF:

import com.spire.doc.Document;
import com.spire.doc.FileFormat;

public class MarkdownToPDF {
   public static void main(String[] args) {
       // Create a Document object
       Document doc = new Document();

       // Load a Markdown file
       doc.loadFromFile("/input/sample.md");

       // Save the markdown file as PDF
       doc.saveToFile("E/output/MarkdowntoPDF.pdf", FileFormat.PDF);
       doc.dispose();
   }
}

Batch Convert Markdown to Word or PDF in Java

Whether you're converting Markdown to Word or PDF, the approach above works best for single or small numbers of files. But if you have multiple Markdown files to process, you’ll want to handle them in a batch. To do that, you can loop through all the Markdown files in a folder and convert each one using the Document.saveToFile() method. Just make sure all the Markdown files are placed in the same directory beforehand. Here’s a code example to demonstrate how batch conversion works.

Code example - batch converting all Markdown files in the same folder to Word documents:

import com.spire.doc.Document;
import com.spire.doc.FileFormat;

import java.io.File;

public class MarkdownToWordBatch {
   public static void main(String[] args) {
       File[] files = new File("/input/newfolder/")
               .listFiles((dir, name) -> name.toLowerCase().endsWith(".md"));

       if (files != null) {
           for (File file : files) {
               Document doc = new Document();
               doc.loadFromFile(file.getAbsolutePath(), FileFormat.Markdown);
               doc.saveToFile("/output/" + file.getName().replace(".md", ".docx"), FileFormat.Docx);
               doc.dispose();
           }
       }
   }
}

The Bottom Line

In this guide, we explored how to convert Markdown files to Word and PDF formats using Java, including how to batch process multiple files with minimal code. With the help of Spire.Doc for Java, the conversion process becomes simple and efficient—whether you're working with a single file or an entire folder.
