## What it is
Uppy is a sleek, modular JavaScript file uploader for web browsers that integrates with any frontend framework via plugins. It fetches files from local disk, remote URLs, and cloud sources like Google Drive and Dropbox, then uploads them via tus, S3, or plain XHR, with optional processing and encoding.

## Use cases
- add a file uploader to a react app
- resumable uploads that survive connection drops
- let users import files from google drive or dropbox
- drag and drop file upload widget
- upload large videos directly to s3
- compress and crop images before upload
- recover file selections after a browser crash

## When to choose
- you need a polished, extensible upload UI without building one from scratch
- you need resumable uploads via the tus protocol
- you want users to pull files from remote sources like Drive, Dropbox, or Instagram
- you use React, Vue, Svelte, Angular, or vanilla JS and want framework integrations

## When to avoid
- you only need a simple single-file form upload with no UI
- you need server-side-only uploads with no browser client
- you cannot run or afford a Companion server but need remote-source imports

## Facets
- artifact type: library
- maturity: stable
- function: file-upload, ui-components, http-client, image-processing, plugin-system
- domain: web-development, frontend, files, developer-tools
- platform: browser, self-hosted
- tags: file-uploader, resumable-uploads, tus-protocol, drag-and-drop, react, vue, svelte, angular, companion-server, remote-sources, image-compression, nodejs, javascript, web-server
