For those having issues with html2canvas, I recommend switching to the modern-screenshot package. It's more lightweight and offers better output quality. Example in this case: https://jsfiddle.net/x1apujzd

$(document).on("click", "#save", function() {
  modernScreenshot.domToCanvas($("body")[0]).then(function(canvas) {
    $("#result_here").append(canvas);
  })
});
