How to use API to combine image files into one?

Open the site: Merge image files . Drag and drop image files to join them. Or just use a code example in JavaScript. Install Node SDK and add the reference (import the library) to your Node project. Open the source image file in JavaScript. Load a document to append from the Cloud storage. Call the appendDocumentOnline() method, passing the output filename with the required extension. Get the combined result as a single file.

What other file formats can I merge my image to?

We support a variety of output file formats, including Microsoft Word, OpenOffice, PDF, Web document formats and many more.

What is the maximum size of a image file supported by this Node library?

Javascript Merge Image REST API

Combine image using JavaScript REST API

Easily merge image files together in JavaScript code. This JavaScript library is designed to combine multiple image files into a single file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native image merging solution that provides JavaScript programmers with both great development flexibility and powerful features. Joining image files together is often used when it is necessary to create a set of documents of the same structure, each of which contains unique data. By merging image files, you can automate your digital workflows and offload some routine parts of the process to fast and efficient image processing JavaScript software.

Merge multiple image into one in JavaScript

You may need to combine image files together in many cases. For example, you may want to combine multiple image files together before printing or archiving.

image merging can be part of a whole integrated document-processing approach for generating documents from disparate data sources. Such tasks involve the use of a full-featured image manipulation JavaScript library that will process a set of image files and merge them together in the shortest possible time, producing a compact and accurate result.

Merge image files in JavaScript

To merge image in JavaScript, you need at least two source image files. For a quick start, please check out the JavaScript code example below.

})
const appendDocumentOnline = new model.AppendDocumentOnlineRequest({
    document: document,
    imageList: imageList
});

wordsApi.appendDocumentOnline(appendDocumentOnline)
.then((appendDocumentOnlineResult) => {
    console.log("Result of AppendDocumentOnline: ", appendDocumentOnlineResult);

    const convertDocument = new model.ConvertDocumentRequest({
        document: appendDocumentOnlineResult,
        format: "png"
    });

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