function base64ToBlob(base64Data, contentType) {
  contentType = contentType || '';
  var sliceSize = 1024;
  var byteCharacters = window.atob(base64Data);
  var byteArrays = [];
  for (var offset = 0; offset < byteCharacters.length; offset += sliceSize) {
    var slice = byteCharacters.slice(offset, offset + sliceSize);
    var byteNumbers = new Array(slice.length);
    for (var i = 0; i < slice.length; i++) {
      byteNumbers[i] = slice.charCodeAt(i);
    }
    var byteArray = new Uint8Array(byteNumbers);
    byteArrays.push(byteArray);
  }
  return new Blob(byteArrays, { type: contentType });
}

// Example usage:
var base64String = "<base64_encoded_data>";
var blob = base64ToBlob(base64String, "image/jpeg");
console.log(blob);
