Modern JavaScript library allows Node.js via .NET developers to convert JPG images to image format with a few lines of code. JPG image conversion engine analyses the original graphical content, and exports the combined picture as a image document.
Use JavaScript to convert JPG images to image format with maximum flexibility and speed. Run online live demo and check the highest output image quality right in a browser. JPG Conversion API supports a bunch of useful options.
To convert several JPG images to image just use JavaScript library that handles all low-level details.
Convert multiple JPG images and save the result as a single image document. If you develop code in JavaScript, image format conversion will be simpler than it sounds. See JavaScript example that iterates through image files and combines them into one image document:
npm install @aspose/words
Copy
const aw = require('@aspose/words');
var fileNames = [ "Input1.jpg", "Input2.jpg" ]
var doc = new aw.Document()
var builder = new aw.DocumentBuilder(doc)
shapes = fileNames.map(fileName => builder.insertImage(fileName))
// Calculate the maximum width and height and update page settings
// to crop the document to fit the size of the pictures.
pageSetup = builder.pageSetup
pageSetup.pageWidth = Math.max(...shapes.map(shape => shape.width));
pageSetup.pageHeight = shapes.reduce((sum, shape) => sum + shape.height, 0);
pageSetup.topMargin = 0
pageSetup.leftMargin = 0
pageSetup.bottomMargin = 0
pageSetup.rightMargin = 0
doc.save("Output.jpg")
