Stand-alone file

Simply download the files

I don't recommend this option, because it is hard to maintain, but sometimes you just have a small project that you don't want to spend any unnecessary time on, and using the stand-alone .js files is fine for you.

Instead of having to download the files yourself, you can directly link to the unpkg host like this:

<script src="https://unpkg.com/dropzone@5/dist/min/dropzone.min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/dropzone@5/dist/min/dropzone.min.css" type="text/css" />

Dropzone is now active and available as window.Dropzone.

Note that the imported css file is optional.

Dropzone v6

Dropzone has dropped Internet Explorer support in version 6, which is still in beta this point. If you already want to use a much lighter script (46kB vs 115kB) and don't care about Internet Explorer support, you can already opt into it like this:

<script src="https://unpkg.com/dropzone@6.0.0-beta.1/dist/dropzone-min.js"></script>
<link href="https://unpkg.com/dropzone@6.0.0-beta.1/dist/dropzone.css" rel="stylesheet" type="text/css" />

If you do, please make sure to check the CHANGELOG to make sure the breaking changes don't affect you.
