HTML & Javascript

One of the many ways to use Transloadit is for handling file uploads in browsers. This makes a good case for using Transloadit with Uppy, our open source file uploader.

This demo embeds Uppyʼs Dashboard to handle uploads:

<button id="browse">Select Files</button>
<script type="module">
  import { Uppy, Dashboard, ImageEditor, RemoteSources, Transloadit }
   from 'https://releases.transloadit.com/uppy/v3.22.2/uppy.min.mjs'
  const uppy = new Uppy()
    .use(Transloadit, {
      waitForEncoding: true,
      assemblyOptions: {
        params: {
          auth: { key: 'YOUR_TRANSLOADIT_KEY' },
          template_id: 'YOUR_TEMPLATE_ID',
    .use(Dashboard, { trigger: '#browse' })
    .use(ImageEditor, { target: Dashboard })
    .use(RemoteSources, {
      companionUrl: 'https://api2.transloadit.com/companion',
    .on('complete', ({ transloadit }) => {
