Base64 Image Encoder - Convert any image file or URL online
Once converted to Base64, encoded image data will look similar to this (shortened for simplicity): iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAMAAABEpIrGAAAABGdBTUEAALGPC/xhBQAAAAFzUkdCAK7OHOkAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwAADqYAAAOpgwnLpRPAAA...

Like
data:image/jpeg;charset=utf-8;base64,
according to the syntax of the data URI scheme:
data:[<media type>][;charset=<character set>][;base64],<data>

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\/?[A-z]*;base64,/);
}
var base64 = getBase64Image(document.getElementById("imageid"));
Special thanks to @Md. Hasan Mahmud for providing an improved regex that works with any image mime type in my comments!
This method requires the canvas element, which is perfectly supported.
- The MDN reference of
HTMLCanvasElement.toDataURL(). - And the official W3C documentation.

Basically, he implemented this function:
function toDataUrl(url, callback) {
var xhr = new XMLHttpRequest();
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function() {
callback(reader.result);
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', url);
xhr.responseType = 'blob';
xhr.send();
}
And in your case, you can use it like this:
toDataUrl(imagepath, function(myBase64) {
console.log(myBase64); // myBase64 is the base64 string
});
