## What it is
A jQuery plugin providing a file upload widget with multiple file selection, drag & drop, progress bars, validation, and media previews. It supports cross-domain, chunked, and resumable uploads and works with any server-side platform handling standard HTML form file uploads.

## Use cases
- add drag and drop file uploads to a web page
- upload multiple files with a progress bar
- resume interrupted large file uploads
- upload large files in chunks
- show image previews before uploading
- upload files cross-domain with ajax

## When to choose
- you need a battle-tested jQuery-based upload widget with broad legacy browser fallbacks
- you need chunked, resumable, or cross-domain uploads without building them yourself
- your stack is any server platform that accepts standard HTML form uploads

## When to avoid
- you use a modern framework like React or Vue and prefer a native or framework-specific uploader
- your project has no jQuery dependency and you want a zero-dependency solution
- you need actively developed features rather than a mature, mostly-maintained plugin

## Facets
- artifact type: library
- maturity: maintenance
- function: file-upload, ui-components, image-processing
- domain: web-development, frontend, files
- platform: browser, php, python, cross-platform
- tags: jquery-plugin, drag-and-drop, resumable-uploads, chunked-uploads, progress-bar, html5, nodejs
