Embed Fonts in Word Documents in Java

If you use a custom font (anything other than Word’s built-in fonts) in your document, embedding those fonts ensures that whoever views the document sees it the way you intended. In this artilce, we will show you how to embed true type fonts when creating a Word document or saving a Word document to a PDF file, by using Free Spire.Doc for Java.

Embed Fonts in a Word Document

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.PrivateFontPath;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.TextRange;

public class EmbedPrivateFont {

    public static void main(String[] args) {

        //create a Word document 
        Document document = new Document();

        //add a paragraph 
        Paragraph paragraph = document.addSection().addParagraph();

        //load the private font
        PrivateFontPath fontPath = new PrivateFontPath();
        fontPath.setFontName("Otto");
        fontPath.setFontPath("C:\\Users\\Administrator\\Desktop\\Otto.TTF");

        //embed a private font in Word document
        document.setEmbedFontsInFile(true);
        document.getPrivateFontList().add(fontPath);

        //add text to the paragraph and apply the embedded font
        TextRange tr = paragraph.appendText("Dev.to \nA publishing platform for developers to share ideas.");

        //apply font to text range
        tr.getCharacterFormat().setFontName("Otto");
        tr.getCharacterFormat().setFontSize(34f);

        //save to file
        document.saveToFile("EmbedFonts.docx", FileFormat.Docx_2013);
    }
}

Embed Fonts in a Converted PDF Document

import com.spire.doc.Document;
import com.spire.doc.PrivateFontPath;
import com.spire.doc.ToPdfParameterList;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.TextRange;

import java.util.*;

public class EmbedPrivateFontInConvertedPDF {

    public static void main(String[] args) {

        //create a Word document 
        Document document = new Document();

        //add a paragraph 
        Paragraph paragraph = document.addSection().addParagraph();

        //load the private font
        PrivateFontPath fontPath = new PrivateFontPath();
        fontPath.setFontName("Otto");
        fontPath.setFontPath("C:\\Users\\Administrator\\Desktop\\Otto.TTF");

        //add text to the paragraph
        TextRange tr = paragraph.appendText("Dev.to \nA publishing platform for developers to share ideas.");

        //apply font to text range
        tr.getCharacterFormat().setFontName("Otto");
        tr.getCharacterFormat().setFontSize(34f);

        //create a list and add the font path as an element
        List<PrivateFontPath> pathList = new LinkedList<>();
        pathList.add(fontPath);

        //create a ToPdfParameterList object and set the private font paths
        ToPdfParameterList toPdfParameterList = new ToPdfParameterList();
        toPdfParameterList.setPrivateFontPaths(pathList);

        //save the document to PDF
        document.saveToFile("EmbedFonts.pdf",toPdfParameterList);
    }
}
