Dropzone is a TypeScript-based browser library that turns ordinary HTML elements into drag-and-drop file upload interfaces. It handles file selection, previews, progress reporting, and XHR-based uploading with minimal setup. Multiple files can be processed together, and large files can be divided into smaller chunks for more reliable transfer. Image uploads can generate thumbnails and resize images in the browser before transmission. The library also supports Amazon S3 multipart upload workflows. Developers can replace default event handlers and styling to fully customize appearance and behavior. Version 6 ships its own TypeScript definitions and is maintained in a monorepo containing the library, documentation, website, tests, and examples.
