GroupDocs.Conversion provides a flexible way to apply watermarks to documents during the conversion process. This feature can be useful for branding, security, or informational purposes. You can customize various aspects of the watermark, such as its text, size, color, position, and transparency.

Tip

Looking for advanced watermarking capabilities? While GroupDocs.Conversion offers basic watermarking, you can explore GroupDocs.Watermark for a comprehensive solution with enhanced features.

You can control how the watermark appears in the converted document using the WatermarkOptions class. Here are the key properties you can set:

• Initialize the Converter: Create an instance of the Converter class, providing the path to the source document.
• Set Conversion Options: Instantiate the appropriate ConvertOptions class (e.g., PdfConvertOptions, WordProcessingConvertOptions, SpreadsheetConvertOptions, etc.).
• Configure Watermark Options: Create an instance of the WatermarkOptions class and configure the properties to specify the watermark’s appearance.
• Apply the Watermark: Use the setWatermark method of the ConvertOptions instance to apply the watermark settings.
• Convert the Document: Call the convert method on the Converter instance, passing the output file name and the configured ConvertOptions instance.

The following Java code snippet demonstrates how to apply a text watermark to a document during conversion to PDF:

import com.groupdocs.conversion.Converter;
import com.groupdocs.conversion.options.convert.PdfConvertOptions;
import com.groupdocs.conversion.options.convert.WatermarkTextOptions;

public class AddWatermarkToConvertedDocument {
    public static void convert() {
        // Initialize the converter with the source document
        try(Converter converter = new Converter("annual-review.docx")){

            // Set conversion options for PDF
            PdfConvertOptions options = new PdfConvertOptions();

            // Configure watermark options
            WatermarkTextOptions watermark = new WatermarkTextOptions("Sample Watermark");
            watermark.setColor(Color.RED);        // Set watermark color to red
            watermark.setWidth(100);              // Set watermark width
            watermark.setHeight(100);             // Set watermark height
            watermark.setBackground(true);        // Set watermark as background
            
            // Apply the watermark to the conversion options
            options.setWatermark(watermark);

            // Convert the document and apply the watermark
            converter.convert("addTextWatermark.pdf", options);
        }
    }

    public static void main(String[] args){
        convert();
    }
}

By following these steps and adjusting the settings, you can easily add customized watermarks to your converted documents using GroupDocs.Conversion.
