Convert Link from Image URL from s3 into File Object using JavaScript

Question

I want to convert my s3 image link into a file object using JavaScript.

I've found out how to do this with an image URI but wasn't able to figure out how to convert the image URL into a URI. Once I do this I could convert it into a file object

Heres the image link:

Source for this code

function getDataUri(url, callback) {
    var image = new Image();

    image.onload = function () {
        var canvas = document.createElement('canvas');
        canvas.width = this.naturalWidth; // or 'width' if you want a special/scaled size
        canvas.height = this.naturalHeight; // or 'height' if you want a special/scaled size

        canvas.getContext('2d').drawImage(this, 0, 0);

        // Get raw image data
        callback(canvas.toDataURL('image/png').replace(/^data:image\/(png|jpg);base64,/, ''));

        // ... or get as Data URI
        callback(canvas.toDataURL('image/png'));
    };

    image.src = url;
}

// Usage
getDataUri('local_location_to_image.extension', function(dataUri) {
    // Do whatever you'd like with the Data URI!
});
