Add a text or image watermark to DOCX documents using Swift. Load the DOCX document and insert the required watermark into it. Then save the result in a convenient format such as DOCX, PDF, MD, HTML, TXT, DOC, RTF, EPUB, XPS and more, and share the watermarked document with another person. Also remove the watermark from DOCX document if the watermark was previously added to the document, and the reasons for adding are not longer relevant.
With this Swift API, developers can add a watermark to DOCX online. Just create the watermark using text or an image and then insert that watermark into your DOCX document in Swift.
Note: there is no need to install any third party applications or libraries. Therefore, our Swift software solution is very easy to use.
The given Swift SDK is also helpful to remove watermarks from DOCX. Removing a watermark in DOCX means that you can load the desired DOCX document stamped with a text or image watermark, remove this watermark from the DOCX using Swift, and then save the output file in a convenient format – DOC, DOCX, PDF, JPEG, PNG, TIFF and others.
To evaluate how to add or remove a watermark in DOCX with our Swift API, load the DOCX and the watermark as an image or text. Then select a convenient export file format – DOC, DOCX, PDF, HTML, RTF, XPS and others.
Use the following example to see how it works:
import AsposeWordsCloud
let config = Configuration(
clientId: "####-####-####-####-####", clientSecret: "##################");
let api = try WordsAPI(configuration: config);
let requestDocument = InputStream(url: URL(string: "Input1.docx"))!;
let requestImageStream = InputStream(url: URL(string: "Input2.jpg"))!;
let requestWatermarkData = WatermarkDataImage()
.setImage(image: FileReference(localFileContent: requestImageStream));
let insertWatermarkRequest = InsertWatermarkOnlineRequest(
document: requestDocument, watermarkData: requestWatermarkData);
let insertWatermarkResult = try api.insertWatermarkOnline(
request: insertWatermarkRequest);
let convertRequest = ConvertDocumentRequest(
document: insertWatermarkResult.document.values.first, format: "docx");
_ = try api.convertDocument(request: convertRequest);
import AsposeWordsCloud
let config = Configuration(
clientId: "####-####-####-####-####", clientSecret: "##################");
let api = try WordsAPI(configuration: config);
let requestDocument = InputStream(url: URL(string: "Input.docx"))!;
let requestWatermarkData = WatermarkDataText()
.setLayout(layout: WatermarkDataText.Layout.diagonal)
.setText(text: "This is the watermark text");
let insertWatermarkRequest = InsertWatermarkOnlineRequest(
document: requestDocument, watermarkData: requestWatermarkData);
let insertWatermarkResult = try api.insertWatermarkOnline(
request: insertWatermarkRequest);
let convertRequest = ConvertDocumentRequest(
document: insertWatermarkResult.document.values.first, format: "docx");
_ = try api.convertDocument(request: convertRequest);
import AsposeWordsCloud
let config = Configuration(
clientId: "####-####-####-####-####", clientSecret: "##################");
let api = try WordsAPI(configuration: config);
let requestDocument = InputStream(url: URL(string: "Input.docx"))!;
let deleteWatermarkOnline = DeleteWatermarkOnlineRequest(document: requestDocument);
let deletedWatermark = try api.deleteWatermarkOnline(request: deleteWatermarkOnline);
let convertDocument = ConvertDocumentRequest(
document: deletedWatermark.document.values.first, format: "docx");
_ = try api.convertDocument(request: convertDocument);
