function readImage(url, callback) {   
    var request = new
    XMLHttpRequest();   request.onload = function() {
       var file = new FileReader();
       file.onloadend = function() {
          callback(file.result);
       }
       file.readAsDataURL(request.response);   };   
       request.open('GET', url);   
       request.responseType = 'blob';              
       request.send(); 
}

and call function

readImage('[path image] ',  function(base64) {  console.info(base64); 
});
