In this article, I’m going to convert an image to base64 string using jQuery. Let’s have a look:

Convert & Display Image

This code will convert an image to base64 and display in the webpage:

<html>
<head>
  <title>Convert Image to Base64 String using jQuery</title>
  <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
</head>
<body>
<form>
  <input type="file" name="file" id="file" onchange="encodeImgtoBase64(this)">
  <button type="submit">Submit</button>
  <br><br>
  <textarea id="base64Code" rows="15" cols="68"></textarea>
  <br><br>
  <img src="" id="base64Img" width="500">
</form>
</body>
<script type="text/javascript">
   function encodeImgtoBase64(element) {
    var file = element.files[0];
    var reader = new FileReader();
    reader.onloadend = function() {
      $("#base64Code").val(reader.result);
      $("#convertImg").text(reader.result);
      $("#base64Img").attr("src", reader.result);
    }
    reader.readAsDataURL(file);
  }
</script>
</html>

Output

Have a look at the output:
