Specific Steps of How to Convert Doc/Docx Files to PDF Format with Spire.Doc for Java

Before going through the sample code, you should know one of the best Word Java library known as Spire.Doc for Java. It supports not only Word file format conversion, but more advanced settings including page size adjustment, font embed, specific area conversion, etc. It is a one time download for long-term benefits.

Follow the steps below to learn how you can convert Word files to PDF format with Spire.Doc for Java.

Step 1. Install Spire.Doc for Java

Before converting, you should add the Spire.Doc.jar file as a dependency in your Java program. You can download the JAR file from the official download page.

If you are using Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file directly:

<repositories>
    <repository>
        <id>com.e-iceblue</id>
        <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>14.7.0</version>
    </dependency>
</dependencies>

Step 2. Convert Word to PDF with Java Code

After library integration, now, it's time to convert your Word files. Copy the code below to your Java program:

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

public class ConvertWordToPdf {

    public static void main(String[] args) {

        // Create a Document object
        Document doc = new Document();

        // Load a Word document
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx");

        // Save the document to PDF
        doc.saveToFile("ToPDF.pdf", FileFormat.PDF);

        // Dispose resources
        doc.dispose();
    }
}

RESULT:

Advanced Settings When Converting Word Files to PDF

Except for simply converting Word to PDF files, Spire.Doc for Java provides more options beyond simply conversion. For example, you can set a password to protect your PDF data with simple code during the conversion. You have no need to look for other tutorials. The following list is a preview of these settings, and you can directly jump to the corresponding part.

• Convert Word files to PDF/A Format with Java Code
• Convert Word Files to Password-Protected PDF in Java
• Convert a Specific Area in Word to PDF in Java

Convert Word files to PDF/A Format with Java Code

Spire.Doc for Java allows you to set the conformance level as Pdf/A-1a. To apply these customized settings, pass the ToPdfParameterList object as a parameter to the Document.saveToFile() method.

Copy the code below to convert your doc/docx to PDF/A files with Java:

import com.spire.doc.Document;
import com.spire.doc.ToPdfParameterList;
import com.spire.doc.PdfConformanceLevel;

public class ConvertWordToPdfa {

    public static void main(String[] args) {

        // Create a Document object
        Document doc = new Document();

        // Load a Word document
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.docx");

        // Create a ToPdfParameterList object
        ToPdfParameterList parameters  = new ToPdfParameterList();

        // Set the conformance level for PDF
        parameters.setPdfConformanceLevel(PdfConformanceLevel.Pdf_A_1_A);

        // Save the document to a PDF file
        doc.saveToFile("C:\\Users\\Administrator\\Desktop\\ToPdfA.pdf", parameters);

        // Dispose resources
        doc.dispose();
    }
}

Convert Word Files to Password-Protected PDF in Java

To protect your data, you may need to set a password for the converted PDF file. In this part, you can encrypt the converted PDF documents with password during the conversion process without any hassle. By passing the ToPdfParameterList object as a parameter to the Document.saveToFile() method, these encryption settings will be applied during the saving process.

Copy the code below to encrypt converted PDF files during conversion with Java:

import com.spire.doc.Document;
import com.spire.doc.PdfPermissionsFlags;
import com.spire.doc.ToPdfParameterList;

public class ConvertWordToPasswordProtectedPdf {

    public static void main(String[] args) {

        // Create a Document object
        Document doc = new Document();

        // Load a Word document
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx");

        // Create a ToPdfParameterList object
        ToPdfParameterList parameters = new ToPdfParameterList();

        // Set open password and permission password for PDF
        parameters.getPdfSecurity().encrypt("openPsd", PdfPermissionsFlags.valueOf("permissionPsd"));

        // Save the document to PDF
        doc.saveToFile("PasswordProtected.pdf", parameters);

        // Dispose resources
        doc.dispose();
    }
}

Convert a Specific Area in Word to PDF in Java

The third section is that you can create a copy of a certain section with Spire.Doc's Section.deepClone() method and use the SectionCollection.add() method to add the copied section to the section collection of another document.

You can easily create a document containing the desired section from the source document with the following Java code:

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

public class ConvertSectionToPdf {

    public static void main(String[] args) {

        // Create a Document object
        Document doc = new Document();

        // Load a Word document
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx");

        // Get a specific section of the document
        Section section = doc.getSections().get(1);

        // Create a new document object
        Document newDoc = new Document();

        // Clone the default style to the new document
        doc.cloneDefaultStyleTo(newDoc);

        // Clone the section to the new document
        newDoc.getSections().add(section.deepClone());

        // Save the new document to PDF
        newDoc.saveToFile("SectionToPDF.pdf", FileFormat.PDF);

        // Dispose resources
        doc.dispose();
        newDoc.dispose();
    }
}

How to Adjust Word Files When Converting Word to PDF with Java Code

To get the best conversion result, you can make more adjustment to your Word documents during the conversion process. For example, you can embed fonts, adjust page size, set image quality, create bookmarks, or modify hyperlink with Java code.

Here, I will take one adjustment as an example to show you how to manage it. If you need to apply other adjustments, you can directly click the link above and jump to the corresponding page.

Example: Set Image Quality During Word to PDF Conversion

Image quality is a vital element when converting DOC/DOCX files to PDF format. It may influence the conversion speed and play an important role in the conversion result. With Spire.Doc for Java, you can set the image quality according to your specific needs to ensure the highest efficiency.

Copy the following code in your Java program to adjust picture quality:

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

public class SetImageQualityDuringConversion {

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

        // Load a Word document
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx");

        // Set the image quality to 50% of the original quality
        doc.setJPEGQuality(50);

        // Preserve original image quality
        // doc.setJPEGQuality(100);

        // Save the document to PDF
        doc.saveToFile("SetImageQuality.pdf", FileFormat.PDF);

        // Dispose resources
        doc.dispose();
    }
}

Final Words

Converting Word to PDF in Java is simple and efficient with Spire.Doc for Java. From basic conversion to advanced options like password protection, section export, and image quality settings, you can handle it all with just a few lines of code.

This article demonstrates how to edit the existing bookmarks in a PDF file, for example, change the bookmark title, font color and text style using Spire.PDF for Java.

import com.spire.pdf.PdfDocument;
import com.spire.pdf.bookmarks.PdfBookmark;
import com.spire.pdf.bookmarks.PdfTextStyle;
import com.spire.pdf.graphics.PdfRGBColor;

import java.awt.*;

public class EditBookmarks {
    public static void main(String[] args) {
        //Create a PdfDocument instance
        PdfDocument doc = new PdfDocument();
        //Load the PDF file
        doc.loadFromFile("Bookmarks.pdf");

        //Get the first bookmark
        PdfBookmark bookmark = doc.getBookmarks().get(0);
        //Change the title of the bookmark
        bookmark.setTitle("New Title");
        //Change the font color of the bookmark
        bookmark.setColor(new PdfRGBColor(new Color(255,0,0)));
        //Change the outline text style of the bookmark
        bookmark.setDisplayStyle(PdfTextStyle.Italic);

        //Edit child bookmarks of the first bookmark
        for (Object Bookmark : (Iterable) bookmark) {
            PdfBookmark childBookmark=(PdfBookmark)Bookmark;
            childBookmark.setColor(new PdfRGBColor(new Color(0,0,255)));
            childBookmark.setDisplayStyle(PdfTextStyle.Bold);

            for (PdfBookmark Bookmark2 : (Iterable⁢PdfBookmark>) bookmark){
                PdfBookmark childBookmark2=(PdfBookmark)Bookmark2;
                childBookmark2.setColor(new PdfRGBColor(new Color(160,160,122)) );
                childBookmark2.setDisplayStyle(PdfTextStyle.Bold);
            }
        }

        //Save the result file
        doc.saveToFile("EditBookmarks.pdf");
        doc.close();
    }
}

Output:

A bookmark in a PDF document consists of formatted text linking to a specific section of the document. Readers can navigate through pages by simply clicking on the bookmarks displayed on the side of the page instead of scrolling up and down, which is very helpful for those huge documents. Moreover, well-organized bookmarks can also serve as contents. When you create a PDF document with a lot of pages, it’s better to add bookmarks to link to significant content. This article is going to show how to add, modify, and remove bookmarks in PDF documents using Spire.PDF for Java through programming.

Check out this video for a quick overview of Excel to PDF conversion in Java before reading the detailed tutorial below.

Using PDF as a format for sending documents ensures that no formatting changes will occur to the original document. Exporting Excel to PDF is a common practice in many cases. This article introduces how to convert a whole Excel document or a specific worksheet to PDF using Spire.XLS for Java.

• Convert a Whole Excel File to PDF
• Convert a Specific Worksheet to PDF

Install Spire.XLS for Java

First of all, you're required to add the Spire.Xls.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.

Convert a Whole Excel File to PDF

The following are the steps to convert a whole Excel document to PDF.

• Create a Workbook object.
• Load a sample Excel document using Workbook.loadFromFile() method.
• Set the Excel to PDF conversion options through the methods under the ConverterSetting object, which is returned by Workbook.getConverterSetting() method.
• Convert the whole Excel document to PDF using Workbook.saveToFile() method.

import com.spire.xls.FileFormat;
import com.spire.xls.Workbook;

public class ConvertExcelToPdf {

    public static void main(String[] args) {

        //Create a Workbook instance and load an Excel file
        Workbook workbook = new Workbook();
        workbook.loadFromFile("C:\\Users\\Administrator\\Desktop\\Sample.xlsx");

        //Set worksheets to fit to page when converting
        workbook.getConverterSetting().setSheetFitToPage(true);

        //Save the resulting document to a specified path
        workbook.saveToFile("output/ExcelToPdf.pdf", FileFormat.PDF);
    }
}

Convert a Specific Worksheet to PDF

The following are the steps to convert a specific worksheet to PDF.

• Create a Workbook object.
• Load a sample Excel document using Workbook.loadFromFile() method.
• Set the Excel to PDF conversion options through the methods under the ConverterSetting object, which is returned by Workbook.getConverterSetting() method.
• Get a specific worksheet using Workbook.getWorksheets().get() method.
• Convert the worksheet to PDF using Worksheet.saveToPdf() method.

import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;

public class ConvertWorksheetToPdf {

    public static void main(String[] args) {

        //Create a Workbook instance and load an Excel file
        Workbook workbook = new Workbook();
        workbook.loadFromFile("C:\\Users\\Administrator\\Desktop\\Sample.xlsx");

        //Set worksheets to fit to width when converting
        workbook.getConverterSetting().setSheetFitToWidth(true);

        //Get the first worksheet
        Worksheet worksheet = workbook.getWorksheets().get(0);

        //Convert to PDF and save the resulting document to a specified path
        worksheet.saveToPdf("output/WorksheetToPdf.pdf");
    }
}

This article demonstrates how to modify hyperlinks in Word including modifying hyperlink address and display text using Spire.Doc for Java.

Below is the sample Word document we used for demonstration:

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.Field;

import java.util.ArrayList;
import java.util.List;

public class ModifyHyperlink {
    public static void main(String[] args) {
        //Load Word document
        Document doc = new Document();
        doc.loadFromFile("Hyperlink.docx");

       ⁢List⁢<Field> hyperlinks = new ArrayList<>();

        //Loop through the section in the document
        for (Section section : (Iterable<Section>) doc.getSections()
                ) {
            //Loop through the section in the document
            for (Paragraph para : (Iterable<Paragraph>) section.getParagraphs()
                    ) {
                for (DocumentObject obj:(Iterable<DocumentObject>) para.getChildObjects()
                     ) {
                    if (obj.getDocumentObjectType().equals(DocumentObjectType.Field)) {
                        Field field = (Field) obj;
                        if (field.getType().equals(FieldType.Field_Hyperlink)) {
                            hyperlinks.add(field);
                        }
                    }
                }
            }
        }

        hyperlinks.get(0).setCode("HYPERLINK \"http://www.google.com\"");
        hyperlinks.get(0).setFieldText("www.google.com");

        doc.saveToFile("EditHyperlink.docx", FileFormat.Docx_2013);
    }
}

Output:
