Getting Started

Uppy is a sleek and modular file uploader. It fetches files from local disk, Google Drive, Instagram, remote urls, cameras etc, and then uploads them to the final destination. It’s fast, has a comprehensible API and lets you worry about more important problems than building a file uploader.

Uppy consists of a core module and various plugins for selecting, manipulating and uploading files.

Here’s the simplest example html page with Uppy (it uses a CDN bundle, while we recommend to use a bundler, see Installation):

<!doctype html>
    <meta charset="utf-8">
    <link href="https://releases.transloadit.com/uppy/v3.3.1/uppy.min.css" rel="stylesheet">
    <div id="drag-drop-area"></div>

    <script type="module">
      import {Uppy, Dashboard, Tus} from "https://releases.transloadit.com/uppy/v3.3.1/uppy.min.mjs"
      var uppy = new Uppy()
        .use(Dashboard, {
          inline: true,
          target: '#drag-drop-area'
        .use(Tus, {endpoint: 'https://tusd.tusdemo.net/files/'})

      uppy.on('complete', (result) => {
        console.log('Upload complete! We’ve uploaded these files:', result.successful)

Try it live

Drag and drop, webcam, basic file manipulation (adding metadata), uploading via tus-resumable uploads or XHR/Multipart is all possible using the Uppy client module.

Adding Companion to the mix enables remote sources such as Instagram, Google Drive, Dropbox, and remote URLs. Uploads from remote sources are handled server-to-server, so a 5 GB video won’t be eating into your mobile data plan. Files are removed from Companion after an upload is complete, or after a reasonable timeout. Access tokens also don’t stick around for long, for security reasons.


Uppy can be used with a module bundler such as Vite, Parcel, or Rollup, or by including it in a script tag.

You may need polyfills if your application supports Internet Explorer or other older browsers. See Browser Support.

With a module bundler

Install the @uppy/core package from npm:

$ npm install @uppy/core

And install the plugins you need separately. The documentation pages for plugins in the sidebar show the necessary npm install commands. You can then import Uppy like so:

npm install @uppy/core @uppy/xhr-upload @uppy/dashboard
// Import the plugins
import Uppy from '@uppy/core'
import XHRUpload from '@uppy/xhr-upload'
import Dashboard from '@uppy/dashboard'

// And their styles (for UI plugins)
// With webpack and `style-loader`, you can import them like this:
import '@uppy/core/dist/style.css'
import '@uppy/dashboard/dist/style.css'

const uppy = new Uppy()
  .use(Dashboard, {
    trigger: '#select-files',
  .use(XHRUpload, { endpoint: 'https://api2.transloadit.com' })

uppy.on('complete', (result) => {
  console.log('Upload complete! We’ve uploaded these files:', result.successful)

Many plugins include a CSS file for the necessary styles in their dist/ folder. The plugin documentation pages will tell you which to use and when. When using several plugin CSS files, some code is duplicated. A CSS minifier like clean-css is recommended to remove the duplicate selectors.

You can also use the joint uppy package, which includes all plugins that are maintained by the Uppy team. Only use it if you have tree-shaking set up in your module bundler, otherwise you may end up sending a lot of unused code to your users.

$ npm install uppy

Then you can import Uppy and plugins like so:

import Uppy, { XHRUpload, DragDrop } from 'uppy'

And add the uppy/dist/uppy.min.css file to your page.


If you are using SCSS in your project, you can include the Uppy SCSS source files, instead of using our prebuilt CSS. Uppy’s SCSS files do assume Node.js-style resolution for @imports, so you may need to configure a resolver.

With a script tag

You can also use a pre-built bundle from Transloadit’s CDN: Edgly. Uppy will attach itself to the global window.Uppy object.

⚠️ The bundle consists of all plugins maintained by the Uppy team. This method is thus not recommended for production, as your users will have to download all plugins, even if you are only using a few of them.

1. Add a script at the bottom of the closing </body> tag:

<script src="https://releases.transloadit.com/uppy/v3.3.1/uppy.min.js"></script>

2. Add CSS to <head>:

<link href="https://releases.transloadit.com/uppy/v3.3.1/uppy.min.css" rel="stylesheet">

3. Initialize at the bottom of the closing </body> tag:

  var uppy = new Uppy.Uppy()
  uppy.use(Uppy.DragDrop, { target: '#drag-drop-area' })
  uppy.use(Uppy.Tus, { endpoint: 'https://tusd.tusdemo.net/files/' })

Browser Support

We aim to support recent versions of Chrome, Firefox, Safari and Edge.

We still provide a bundle which should work on IE11, but we are not running tests on it.


Uppy heavily uses Promises. If your target environment does not support Promises, use a polyfill like core-js before initialising Uppy.

When using remote providers like Google Drive or Dropbox, the Fetch API is used. If your target environment does not support the Fetch API, use a polyfill like whatwg-fetch before initialising Uppy. The Fetch API polyfill must be loaded after the Promises polyfill, because Fetch uses Promises.

With a module bundler, you can use the required polyfills like so:

npm install core-js whatwg-fetch abortcontroller-polyfill md-gum-polyfill resize-observer-polyfill
import 'core-js'
import 'whatwg-fetch'
import 'abortcontroller-polyfill/dist/polyfill-patch-fetch'
// Order matters: AbortController needs fetch which needs Promise (provided by core-js).

import 'md-gum-polyfill'
import ResizeObserver from 'resize-observer-polyfill'

window.ResizeObserver ??= ResizeObserver

export { default } from '@uppy/core'
export * from '@uppy/core'

If you’re using Uppy from CDN, those polyfills are already included in the bundle, no need to include anything additionally:

<script src="https://releases.transloadit.com/uppy/v3.3.1/uppy.min.js"></script>
