Compress document in JavaScript

Using our powerful JavaScript API, developers can compress files 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 file format or any available save format – DOCX, DOC, RTF, PDF, HTML and many others.

Reduce file size in JavaScript

As mentioned, our Node SDK allows you to programmatically reduce the size of a document in any supported format. For example, you can reduce the file size of PDF, DOCX, DOC, RTF, ODT, EPUB, HTML and other formats. And now you can try our powerful functionality and evaluate how to compress a document in JavaScript with the following example:

Compress file using JavaScript

Input file

Upload a file you want to optimize/compress

Output format

Select the target format from the list

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: "docx"
    });

    wordsApi.convertDocument(convertDocument)
    .then((convertDocumentResult) => {
        console.log("Result of ConvertDocument: ", convertDocumentResult);
    });
});
