var pdff ;
function encodeImageFileAsURL(element) {
  var file = element.files[0];
  var reader = new FileReader();
  reader.onloadend = function() {
    console.log(reader.result)
    pdff = reader.result;
    pdf();
  }
  reader.readAsDataURL(file);
}
function pdf() {
    var doc = new jsPDF();
var img = new Image();
img.src = pdff;
var width = doc.internal.pageSize.getWidth;
var height = doc.internal.pageSize.getHeight;



 doc.addImage(img, 'JPG', 0, 0, width, height);
    doc.save('imkk.pdf'); // downloads pdf 
}
