Uppy logo: a superman puppy in a pink suit

Build Status

Uppy is a sleek, modular file uploader that integrates seamlessly with any application. It’s fast, easy to use and lets you worry about more important problems than building a file uploader.

  • Fetch files from local disk, Google Drive, Dropbox, Instagram, or snap and record selfies with a camera;
  • Preview and edit metadata with a nice interface;
  • Upload to the final destination, optionally process/encode

Read the docs | Try Uppy

Uppy is being developed by the folks at Transloadit, a versatile file encoding service.


Uppy UI Demo: modal dialog with a few selected files and an upload button

Code used in the above example:

const Uppy = require('uppy/lib/core')
const Dashboard = require('uppy/lib/plugins/Dashboard')
const GoogleDrive = require('uppy/lib/plugins/GoogleDrive')
const Instagram = require('uppy/lib/plugins/Instagram')
const Webcam = require('uppy/lib/plugins/Webcam')
const Tus = require('uppy/lib/plugins/Tus')
const uppy = Uppy({ autoProceed: false })
  .use(Dashboard, { trigger: '#select-files' })
  .use(GoogleDrive, { target: Dashboard, host: '' })
  .use(Instagram, { target: Dashboard, host: '' })
  .use(Webcam, { target: Dashboard })
  .use(Tus, { endpoint: '' })
  .on('complete', (result) => {
    console.log('Upload result:', result)

  • Lightweight, modular plugin-based architecture, easy on dependencies ⚡️
  • Resumable file uploads via the open tus standard, so large uploads survive network hiccups
  • Supports picking files from: Webcam, Dropbox, Google Drive, Instagram, bypassing the user’s device where possible, syncing between servers directly via uppy-server
  • Works great with file encoding and processing backends, such as Transloadit, works great without (just roll your own Apache/Nginx/Node/FFmpeg/etc backend)
  • Sleek user interface ✨
  • Optional file recovery (after a browser crash) with Golden Retriever
  • Speaks multiple languages (i18n) 🌍
  • Built with accessibility in mind
  • Free for the world, forever (as in beer 🍺, pizza 🍕, and liberty 🗽)
  • Cute as a puppy, also accepts cat pictures 🐶


$ npm install uppy --save

We recommend installing from npm and then using a module bundler such as Webpack, Browserify or Rollup.js.

Add CSS uppy.min.css, either to <head> of your HTML page or include in JS, if your bundler of choice supports it — transforms and plugins are available for Browserify and Webpack.

Alternatively, you can also use a pre-built bundle, for example from unpkg CDN. In that case, Uppy will attach itself to the global window.Uppy object.

⚠️ The bundle currently consists of most Uppy plugins, so this method is not recommended for production, as your users will have to download all plugins when you are likely using just a few.

1. Add a script to the bottom of <body>:

<script src=""></script>

2. Add CSS to <head>:

<link href="" rel="stylesheet">

3. Initialize:

<div class="UppyDragDrop"></div>
  var uppy = Uppy.Core()
  uppy.use(Uppy.DragDrop, { target: '.UppyDragDrop' })
  uppy.use(Uppy.Tus, { endpoint: '//' })

Browser Support

Sauce Test Status

We aim to support IE10+ and recent versions of Safari, Edge, Chrome, Firefox, and Opera.


React support?

Yep, we have Uppy React components, please see Uppy React docs.

Can I use it with Rails/Node/Go/PHP?

Yes, whatever you want on the backend will work with XHRUpload plugin, since it just does a POST or PUT request. If you want resumability with the Tus plugin, use one of the tus server implementations 👌🏼

Do I need to install special service/server for it?

Nope, as mentioned previously, the XHRUpload plugin is old-school and just works with everything. However, you need uppy-server if you’d like your users to be able to pick files from Instagram, Google Drive or Dropbox (more services coming). And you can add tus if you want resumability.

Does Uppy support S3 uploads?

Yes, there is an S3 plugin, check out the docs for more!

Why is all this goodness free?

Transloadit's team is small and we have a shared ambition to make a living from open source. By giving away projects like and Uppy, we're hoping to advance the state of the art, make life a tiny little bit better for everyone, and in doing so have rewarding jobs and get some eyes on our commercial service: a content ingestion & processing platform. Our thinking is that if just a fraction of our open source userbase can see the appeal of hosted versions straight from the source, that could already be enough to sustain our work. So far this is working out! We're able to dedicate 80% of our time to open source and haven't gone bankrupt just yet :D
