Convert Base64 To Image In Javascript Jquery

Base64 encoding is a common way to represent binary data in a human-readable format, which can be particularly handy when working with images in web development. In this guide, we'll walk you through how to convert Base64 data to an image using JavaScript and jQuery.

To get started, you'll need a Base64 encoded image string. This string typically starts with "data:image/png;base64," followed by a long sequence of characters representing the image data. If you're unsure about how to obtain this string, you can find tools online that will help you convert an image to Base64.

First, let's create a simple HTML file with an empty image tag and a button to trigger the conversion process:

<title>Base64 to Image Converter</title>


    <img id="output-image" />
    <button id="convert-button">Convert Base64 to Image</button>

Next, create a JavaScript file named `script.js` to handle the conversion process:

$(document).ready(function() {
    $('#convert-button').on('click', function() {
        var base64String = YOUR_BASE64_STRING_HERE; // Replace this with your actual Base64 string
        var imageUrl = 'data:image/png;base64,' + base64String;
        
        $('#output-image').attr('src', imageUrl);
    });
});

In the JavaScript code snippet above, we use jQuery to listen for a click event on the button with the ID `convert-button`. When the button is clicked, we update the `src` attribute of the image tag with the Base64 data.

Remember to replace `YOUR_BASE64_STRING_HERE` with your actual Base64 string before testing the code. Once you've made the necessary modifications, open the HTML file in a browser and click the "Convert Base64 to Image" button to see your image displayed on the page.

This straightforward approach allows you to easily convert Base64 data to an image using JavaScript and jQuery. By following these steps, you can integrate this functionality into your web projects and enhance the user experience by dynamically loading images encoded in Base64 format.

In conclusion, converting Base64 data to an image in JavaScript and jQuery is a practical way to work with images in web development. This method provides a convenient solution for displaying images without the need for additional server requests. Try it out in your projects and explore the possibilities of working with Base64-encoded images on the web.
