Converting JPG to PDF using JavaScript
Introduction
In the era of digitalization, everything needs to be digitalized, and images are no exception. Many times we need to convert images from one format to another, and one such conversion is from JPG to PDF. In this blog post, we will discuss how to convert JPG to PDF using JavaScript.
Converting JPG to PDF using jsPDF library
The easiest way to convert JPG to PDF using JavaScript is by using the jsPDF library. It is an open-source library that allows us to generate PDF documents using JavaScript. To use this library, we need to download it or add it to our project using npm.
We can use the following code snippet to convert a JPG image to PDF using the jsPDF library:
javascript
var imgData = 'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wCEAA...'; // Base64-encoded image data
var doc = new jsPDF();
doc.addImage(imgData, 'JPEG', 10, 10, 100, 100); // Adding image to the PDF document
doc.save('image.pdf'); // Saving the PDF document
In the above code, we first define the base64-encoded image data of the JPG image. We then create a new instance of the jsPDF object. Finally, we add the image to the PDF document using the addImage() method and save the PDF document using the save() method.
Converting JPG to PDF using HTML2PDF.js library
Another library that we can use to convert JPG to PDF using JavaScript is the HTML2PDF.js library. It is a JavaScript library that allows us to generate PDF documents from HTML content. To use this library, we need to download it or add it to our project using npm.
We can use the following code snippet to convert a JPG image to PDF using the HTML2PDF.js library:
javascript
var imgData = 'data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wCEAA...'; // Base64-encoded image data
var doc = new jsPDF();
doc.html('<img src="' + imgData + '"/>', {
callback: function (doc) {
doc.save('image.pdf'); // Saving the PDF document
}
});
In the above code, we first define the base64-encoded image data of the JPG image. We then create a new instance of the jsPDF object. Finally, we add the image to the PDF document using the html() method and save the PDF document using the save() method.
Conclusion
Converting JPG to PDF using JavaScript is a simple and efficient process, and we can achieve it using various libraries. In this blog post, we discussed two popular libraries, i.e., jsPDF and HTML2PDF.js, that we can use to convert JPG to PDF using JavaScript. We hope this blog post helps you in your future projects.
