Drag a ong or pdf file from your desktop 
and drop it on the dropzone.

It acts like a standard input type file when 
the parent form is submitted.

If it doesn't work properly in the codepen window

I end up developing a jQuery plugin...

You can fork it on Github:

Here is the quick demo:


<div id="dropzone">
  <input type="file" accept="image/png, application/pdf" />
              body {
  background: #333;

#dropzone {
  position: relative;
  border: 10px dotted #FFF;
  border-radius: 20px;
  color: white;
  font: bold 24px/200px arial;
  height: 200px;
  margin: 30px auto;
  text-align: center;
  width: 200px;

#dropzone.hover {
  border: 10px solid #FE5;
  color: #FE5;

#dropzone.dropped {
  background: #222;
  border: 10px solid #444;

#dropzone div {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;

#dropzone img {
  border-radius: 10px;
  vertical-align: middle;
  max-width: 95%;
  max-height: 95%;

#dropzone [type="file"] {
  cursor: pointer;
  position: absolute;
  opacity: 0;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
              $(function() {
  $('#dropzone').on('dragover', function() {
  $('#dropzone').on('dragleave', function() {
  $('#dropzone input').on('change', function(e) {
    var file = this.files[0];

    if (this.accept && $.inArray(file.type, this.accept.split(/, ?/)) == -1) {
      return alert('File type not allowed.');
    $('#dropzone img').remove();
    if ((/^image\/(gif|png|jpeg)$/i).test(file.type)) {
      var reader = new FileReader(file);

      reader.onload = function(e) {
        var data = e.target.result,
            $img = $('<img />').attr('src', data).fadeIn();
        $('#dropzone div').html($img);
    } else {
      var ext = file.name.split('.').pop();
      $('#dropzone div').html(ext);
