A hyperlink is the most important element that we use in digital documents to make connections between two things. When readers click on a hyperlink in a Word document, it will take them to a different location within the document, to a different file or website, or to a new email message. This article introduces how to add hyperlinks to Word documents in Java using Spire.Doc for Java.
Install Spire.Doc for Java
First, 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.

Insert Hyperlinks When Adding Paragraphs to Word
Spire.Doc for Java offers the Paragraph.appendHyperlink() method to add a web link, an email link, a file link, or a bookmark link to a piece of text or an image inside a paragraph. The following are the detailed steps.
- Create a Document object.
- Add a section and a paragraph to it.
- Insert a hyperlink based on text using Paragraph.appendHyerplink(String link, String text, HyperlinkType type) method.
- Add an image to the paragraph using Paragraph.appendPicture() method.
- Add a hyperlink to the image using Paragraph.appendHyerplink(String link, DocPicture picture, HyperlinkType type) method.
- Save the document using Document.saveToFile() method.
- Java
import com.spire.doc.BookmarkStart;
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.BreakType;
import com.spire.doc.documents.HyperlinkType;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.DocPicture;
public class InsertHyperlinks {
public static void main(String[] args) {
//Create a Word document
Document doc = new Document();
//Add a section
Section section = doc.addSection();
//Add a paragraph
Paragraph paragraph = section.addParagraph();
paragraph.appendHyperlink("https://www-iceblue.com/", "Home Page", HyperlinkType.Web_Link);
//Append line breaks
paragraph.appendBreak(BreakType.Line_Break);
paragraph.appendBreak(BreakType.Line_Break);
//Add an email link
paragraph.appendHyperlink("mailto:support@e-iceblue.com", "Mail Us", HyperlinkType.E_Mail_Link);
//Append line breaks
paragraph.appendBreak(BreakType.Line_Break);
paragraph.appendBreak(BreakType.Line_Break);
//Add a file link
String filePath = "C:\\Users\\Administrator\\Desktop\\report.xlsx";
paragraph.appendHyperlink(filePath, "Click to open the report", HyperlinkType.File_Link);
//Append line breaks
paragraph.appendBreak(BreakType.Line_Break);
paragraph.appendBreak(BreakType.Line_Break);
//Add another section and create a bookmark
Section section2 = doc.addSection();
Paragraph bookmarkParagraph = section2.addParagraph();
bookmarkParagraph.appendText("Here is a bookmark");
BookmarkStart start = bookmarkParagraph.appendBookmarkStart("myBookmark");
bookmarkParagraph.getItems().insert(0, start);
bookmarkParagraph.appendBookmarkEnd("myBookmark");
//Link to the bookmark
paragraph.appendHyperlink("myBookmark", "Jump to a location inside this document", HyperlinkType.Bookmark);
//Append line breaks
paragraph.appendBreak(BreakType.Line_Break);
paragraph.appendBreak(BreakType.Line_Break);
//Add an image link
String imagePath = "C:\\Users\\Administrator\\Desktop\\logo.png";
DocPicture picture = paragraph.appendPicture(imagePath);
paragraph.appendHyperlink("https://www.e-iceblue.com/", picture, HyperlinkType.Web_Link);
//Save to file
doc.saveToFile("output/InsertHyperlinks.docx", FileFormat.Docx_2013);
}
}
Add Hyperlinks to Existing Text in Word
Adding hyperlinks to existing text in a document is a bit more complicated. You need to find the target string first, and then replace it in the paragraph with a hyperlink field. The following are the steps.
- Create a Document object.
- Load a Word file using Document.loadFromFile() method.
- Find all the occurrences of the target string in the document using Document.findAllString() method, and get the specific one by its index from the collection.
- Get the string’s own paragraph and its position in it.
- Remove the string from the paragraph.
- Create a hyperlink field and insert it to position where the string is located.
- Save the document to another file using Document.saveToFle() method.
- Java
import com.spire.doc.Document;
import com.spire.doc.FieldType;
import com.spire.doc.FileFormat;
import com.spire.doc.Hyperlink;
import com.spire.doc.documents.*;
import com.spire.doc.fields.Field;
import com.spire.doc.fields.FieldMark;
import com.spire.doc.fields.TextRange;
import com.spire.doc.interfaces.IParagraphBase;
import com.spire.doc.interfaces.ITextRange;
import java.awt.*;
public class AddHyperlinksToExistingText {
public static void main(String[] args) {
//Create a Document object
Document document = new Document();
//Load a Word file
document.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.docx");
//Find all the occurrences of the string "Java" in the document
TextSelection[] selections = document.findAllString("Java", true, true);
//Get the second occurrence
TextRange range = selections[1].getAsOneRange();
//Get its owner paragraph
Paragraph paragraph = range.getOwnerParagraph();
//Get its position in the paragraph
int index = paragraph.getItems().indexOf(range);
//Remove it from the paragraph
paragraph.getItems().remove(range);
//Create a hyperlink field
Field field = new Field(document);
field.setType(FieldType.Field_Hyperlink);
Hyperlink hyperlink = new Hyperlink(field);
hyperlink.setType(HyperlinkType.Web_Link);
hyperlink.setUri("https:\\en.wikipedia.org\\wiki\\Java_(programming_language)");
paragraph.getItems().insert(index, field);
//Insert a field mark "start" to the paragraph
IParagraphBase item = document.createParagraphItem(ParagraphItemType.Field_Mark);
FieldMark start = (FieldMark)item;
start.setType(FieldMarkType.Field_Separator);
paragraph.getItems().insert(index + 1, start);
//Insert a text range between two field marks
ITextRange textRange = new TextRange(document);
textRange.setText("Java");
textRange.getCharacterFormat().setFontName(range.getCharacterFormat().getFontName());
textRange.getCharacterFormat().setFontSize(range.getCharacterFormat().getFontSize());
textRange.getCharacterFormat().setBold(range.getCharacterFormat().getBold());
textRange.getCharacterFormat().setTextColor(Color.blue);
textRange.getCharacterFormat().setUnderlineStyle(UnderlineStyle.Single);
paragraph.getItems().insert(index + 2, textRange);
//Insert a field mark "end" to the paragraph
IParagraphBase item2 = document.createParagraphItem(ParagraphItemType.Field_Mark);
FieldMark end = (FieldMark)item2;
end.setType(FieldMarkType.Field_End);
paragraph.getItems().insert(index + 3, end);
//Save to file
document.saveToFile("output/AddHyperlink.docx", FileFormat.Docx_2013);
}

Rotate a Specific Page in PDF in Java
Rotation is based on 90-degree increments. You can rotate a PDF page by 0/90/180/270 degrees. The following are the steps to rotate a PDF page:
- Create an instance of PdfDocument class.
- Load a PDF document using PdfDocument.loadFromFile() method.
- Get the desired page by its index (zero-based) using PdfDocument.getPages().get(pageIndex) method.
- Get the original rotation angle of the page using PdfPageBase.getRotation().getValue() method.
- Increase the original rotation angle by desired degrees.
- Apply the new rotation angle to the page using PdfPageBase.setRotation() method.
- Save the result document using PdfDocument.saveToFile() method.
- Java
import com.spire.pdf.PdfDocument;
import com.spire.pdf.PdfPageBase;
import com.spire.pdf.PdfPageRotateAngle;
public class RotatePdfPage {
public static void main(String []args){
//Create a PdfDocument instance
PdfDocument pdf = new PdfDocument();
//Load a PDF document
pdf.loadFromFile("Sample.pdf");
//Get the first page
PdfPageBase page = pdf.getPages().get(0);
//Get the original rotation angle of the page
int rotation = page.getRotation().getValue();
//Rotate the page 180 degrees clockwise based on the original rotation angle
rotation += PdfPageRotateAngle.Rotate_Angle_180.getValue();
page.setRotation(PdfPageRotateAngle.fromValue(rotation));
//Save the result document
pdf.saveToFile("Rotate.pdf");
}
}
Rotate All Pages in PDF in Java
The following are the steps to rotate all pages in a PDF document:
- Create an instance of PdfDocument class.

public class RotateAllPdfPages {
public static void main(String []args){
//Create a PdfDocument instance
PdfDocument pdf = new PdfDocument();
//Load a PDF document
pdf.loadFromFile("Sample.pdf");
//Loop through each page in the document
for(PdfPageBase page :(Iterable) pdf.getPages()) {
//Get the original rotation angle of the page
int rotation = page.getRotation().getValue();
//Rotate the page 180 degrees clockwise based on the original rotation angle
rotation += PdfPageRotateAngle.Rotate_Angle_180.getValue();
page.setRotation(PdfPageRotateAngle.fromValue(rotation));
