Using our powerful Swift API, developers can compress PDF documents to optimize content and output file size. Reducing PDF size occurs by cleaning up unused data and resources. You can also compress images inside PDF to make the output file size even smaller.
The result of content optimization and compression can be saved in the original PDF or any available save format – DOCX, DOC, RTF, HTML and many others. For example, compress PDF and save the output as Word.
As mentioned, our Swift SDK allows you to programmatically reduce PDF size. And now you can try our powerful functionality and evaluate how to compress PDF in Swift with the following example:
import AsposeWordsCloud
let config = Configuration(clientId: "####-####-####-####-####",
clientSecret: "##################");
let api = try WordsAPI(configuration: config);
let requestDocument = InputStream(url: URL(string: "Input.pdf"))!;
let requestCompressOptions = CompressOptions()
.setImagesQuality(imagesQuality: 75)
.setImagesReduceSizeFactor(imagesReduceSizeFactor: 1);
let compressDocumentRequest = CompressDocumentOnlineRequest(
document: requestDocument, compressOptions: requestCompressOptions);
let compressDocument = try api.compressDocumentOnline(request: compressDocumentRequest);
let convertDocument = ConvertDocumentRequest(
document: compressDocument.document.values.first, format: "pdf");
_ = try api.convertDocument(request: convertDocument);You can use Swift package manager and Cocoapods dependency manager to install Aspose.Words Cloud SDK for Swift. Detailed information on installing the package is given in the "Installation and Usage" section.
As an alternative, you can clone Aspose.Words Cloud SDK for Swift source code from GitHub and use it in your project.
