Compress JPG in JavaScript

Using our powerful JavaScript API, developers can compress JPG to optimize content and output file size. Reducing file size occurs by cleaning up unused data and resources. You can also compress images to make the output file size even smaller.

The result of content optimization and compression can be saved in the original JPG or any available save format – DOCX, DOC, RTF, PDF, HTML and many others.

import * as fs from "fs";

const wordsApi = new WordsApi("####-####-####-####-####", "##################");

const requestDocument = fs.createReadStream("Input.jpg");
const requestCompressOptions = new model.CompressOptions({
    imagesQuality: 75,
    imagesReduceSizeFactor: 1
const compressDocumentRequest = new model.CompressDocumentOnlineRequest({
    document: requestDocument,
    compressOptions: requestCompressOptions

.then((compressDocumentResult) => {
    const requestDocument = compressDocumentResult.Document.Values();
    const convertDocument = new model.ConvertDocumentRequest({
        document: requestDocument,
        format: "jpg"

    .then((convertDocumentResult) => {
        console.log("Result of ConvertDocument: ", convertDocumentResult);
Run code
