We currently do not accept EPUB files as input. But we can produce EPUB files as an output. We look forward to full EPUB support in the near future.
Using our powerful JavaScript API, developers can compress EPUB documents to optimize content and output file size. Reducing EPUB size occurs by cleaning up unused data and resources. You can also compress images inside EPUB to make the output file size even smaller.
The result of content optimization and compression can be saved in the original EPUB or any available save format – DOCX, DOC, RTF, HTML and many others. For example, compress EPUB and save the output as Word.
As mentioned, our Node SDK allows you to programmatically reduce EPUB size. And now you can try our powerful functionality and evaluate how to compress EPUB in JavaScript with the following example:
import * as fs from "fs";
const wordsApi = new WordsApi("####-####-####-####-####", "##################");
const requestDocument = fs.createReadStream("Input.docx");
const requestCompressOptions = new model.CompressOptions({
imagesQuality: 75,
imagesReduceSizeFactor: 1
})
const compressDocumentRequest = new model.CompressDocumentOnlineRequest({
document: requestDocument,
compressOptions: requestCompressOptions
});
wordsApi.compressDocumentOnline(compressDocumentRequest)
.then((compressDocumentResult) => {
const requestDocument = compressDocumentResult.Document.Values();
const convertDocument = new model.ConvertDocumentRequest({
document: requestDocument,
format: "epub"
});
wordsApi.convertDocument(convertDocument)
.then((convertDocumentResult) => {
console.log("Result of ConvertDocument: ", convertDocumentResult);
});
});Install 'Aspose.Words Cloud SDK for Node.js' using NPM package manager. Run npm install asposewordscloud --save from the command line to install the SDK via the NPM package manager. As an alternative, you can manually clone Aspose.Words Cloud SDK for Node.js source code from GitHub and use it in your project. Please follow these Instructions to quickly get the necessary security credentials and access our REST API.
