## What it is
Fine Uploader is a dependency-free vanilla JavaScript file upload library supporting multiple file uploads with drag-and-drop, progress bars, image previews, chunking, resume, and direct-to-S3/Azure uploads. The project has been officially discontinued and is no longer maintained.

## Use cases
- add drag and drop file uploads to a web page
- upload files directly to S3 from the browser
- show upload progress bars and image previews
- chunk and resume large file uploads
- scale images client-side before uploading
- multiple file upload without jQuery dependencies

## When to choose
- you need a battle-tested, dependency-free uploader and accept no future updates
- you want direct-to-S3 or Azure uploads with chunking and resume
- you must support legacy browsers with a single JS file

## When to avoid
- starting a new project - the project is officially shut down and unmaintained
- you need security patches or active community support
- you want a framework-integrated uploader with modern tooling

## Facets
- artifact type: library
- maturity: abandoned
- function: file-upload, ui-components, image-processing
- domain: web-development, frontend, files
