CONVERT Image url to Base64

The Solution to CONVERT Image url to Base64 is


HTML

<img id=imageid src=https://www.google.de/images/srpr/logo11w.png>

JavaScript

function getBase64Image(img) {
  var canvas = document.createElement("canvas");
  canvas.width = img.width;
  canvas.height = img.height;
  var ctx = canvas.getContext("2d");
  ctx.drawImage(img, 0, 0);
  var dataURL = canvas.toDataURL("image/png");
  return dataURL.replace(/^data:image\/(png|jpg);base64,/, "");
}

var base64 = getBase64Image(document.getElementById("imageid"));

This method requires the canvas element, which is perfectly supported.
