# Uppy

> The open source JavaScript file uploader

Uppy is an open source JavaScript file uploader for the browser. It
uploads from disk and from remote sources such as Google Drive, Dropbox
and OneDrive, resumes interrupted uploads over the tus protocol, and has
official bindings for React, Vue, Svelte and Angular.

For a Markdown twin, replace the HTML URL’s trailing slash with `.md`
(`/docs/quick-start/` becomes `/docs/quick-start.md`).
