Java: Convert Word to Password-Protected PDF

 Spire.Doc for Java allows developers to convert Word documents to password-protected PDF documents by using the Document.saveToFile(String, ToPdfParameterList) method. The ToPdfParameterList parameter controls how a Word document will be converted to PDF, for example, whether to encrypt the document while converting.

Install Spire.Doc for Java

First of all, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

    <repositories>
        <repository>

            <name>e-iceblue</name>
            <url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>
        </repository>
    </repositories>
    <dependencies>
        <dependency>
            <groupId>e-iceblue</groupId>
            <artifactId>spire.doc</artifactId>
            <version>4.10.9</version>
        </dependency>

    Convert Word to Password-Protected PDF

    The following are the steps to convert a Word document to password-protected PDF:

    • Create a Document instance.
    • Load a Word document using Document.loadFromFile() method.
    • Create a ToPdfParameterList instance.
    • Set open password and permission password for PDF using ToPdfParameterList.getPdfSecurity().encrypt() method.
    • Save the Word document to PDF with password using Document.saveToFile(String, ToPdfParameterList) method.
    • Java
    import com.spire.doc.Document;
    import com.spire.doc.ToPdfParameterList;
    import com.spire.pdf.security.PdfEncryptionKeySize;
    import com.spire.pdf.security.PdfPermissionsFlags;
    
    public class ConvertWordToPasswordProtectedPDF {
        public static void main(String[] args){
    
            //Create a Document instance
            Document document = new Document();
            //Load a Word document
            document.loadFromFile("Sample.docx");
    
            //Create a ToPdfParameterList instance
            ToPdfParameterList toPdf = new ToPdfParameterList();
            //Set open password and permission password for PDF
            String password = "password";
            toPdf.getPdfSecurity().encrypt(password, password, PdfPermissionsFlags.None, PdfEncryptionKeySize.Key_128_Bit);
    
            //Save the Word document to PDF with password
            document.saveToFile("ToPdfWithPassword.pdf", toPdf);
        }
    }
