Sample Code

Free Spire.Doc for Java allows you to load an ODT file using Document.loadFromFile() method, and then you can convert it to PDF using Document.saveToFile(String fileName, FileFormat fileFormat) method. The complete sample code is shown as below.

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

public class ConvertOdtToPdf {
    public static void main(String[] args){
        //Create a Document instance
        Document doc = new Document();
        //Load an ODT file

        //Save the ODT file to PDF
        doc.saveToFile("OdtToPDF.pdf", FileFormat.PDF);
