You can use the LEADTOOLS Document SDK in your application https://www.leadtools.com/sdk/products/document You can utilize the AnnBatesStampComposer class to add a watermark to your documents. Here is some sample code: private void AddWatermarkToDocument() { //Create AnnBatesStamp and set its properties AnnBatesStamp batesStamp = new AnnBatesStamp(); batesStamp.Font = new AnnFont( "Arial" , 12); batesStamp.Foreground = AnnSolidColorBrush.Create( "Red" ); batesStamp.HorizontalAlignment = AnnHorizontalAlignment.Center; batesStamp.VerticalAlignment = AnnVerticalAlignment.Center; batesStamp.Logo.Angle = 45; batesStamp.Logo.Font = new AnnFont( "Arial" , 14); batesStamp.Logo.Opacity = 0.5; batesStamp.Logo.StretchLogo = true ; batesStamp.Logo.Picture = new AnnPicture(Path.Combine(ImagesPath.Path, "cannon.jpg" )); //Add some elements to Bates stamp elements list batesStamp.Elements.Add( new AnnBatesNumber()); batesStamp.Elements.Add(AnnBatesText.Create( " " )); batesStamp.Elements.Add(AnnBatesText.Create( " This is text element" )); //Create AnnBatesStampComposer instance and add the created Bates stamp to it AnnBatesStampComposer batesStampComposer = new AnnBatesStampComposer(); //Set the rendering engine AnnBatesStampComposer.RenderingEngine = new AnnWinFormsRenderingEngine(); batesStampComposer.Stamps.Add(batesStamp); //Use the main automation object for your application instead of _automation we used here AnnAutomation automation = _automation; AnnContainer mainContainer = automation.Container; //Create Bates stamp container, set its size and mapper and attach it to the composer AnnContainer batesStampContainer = new AnnContainer(); batesStampContainer.Size = mainContainer.Size; batesStampContainer.Mapper = mainContainer.Mapper.Clone(); //Apply Bates Stamp to our container batesStampComposer.TargetContainers.Add(batesStampContainer); //insert the Bates stamp container below all other containers in the automation automation.Containers.Insert(0, batesStampContainer); //print the content of this Bates stamp Debug.WriteLine(batesStamp.AsString(batesStampContainer)); // the output will be "000001 This is text element" //Render the containers automation.Invalidate(LeadRectD.Empty); }

Here is a free solution based on Free Spire.Doc. //create a new instance of Document and load the document from file. Document doc = new Document(); doc.LoadFromFile( "Sample.docx" , FileFormat.Docx2013); //create a new instance of the TextWatermark TextWatermark txtWatermark = new TextWatermark(); //set the text watermark with text string, font, color and layout. txtWatermark.Text = "Confidential" ; txtWatermark.FontSize = 45; txtWatermark.Color = Color.Green; txtWatermark.Layout = WatermarkLayout.Diagonal; //add the text watermark doc.Watermark = txtWatermark; //save the file. doc.SaveToFile( "TextWatermark.docx" , FileFormat.Docx2013); See also: https://www.e-iceblue.com/Tutorials/Spire.Doc/Spire.Doc-Program-Guide/Page-Background/Add-text-watermark-and-image-watermark-to-word-document-in-C.html
