SWFUpload is a client-side tool developed by Mammon.se. It uses a combination Flash and JavaScript to provide file upload functionality beyond what the basic browser provides with <input type="file" />. See it in action!

The main features that SWFUpload provides are:

• Select multiple files in the file browser dialog.
• AJAX-style uploading without a page refresh.
• Upload progress indicator.
• Graceful degradation for unsupported browsers.
• Namespaced classes compatible with other JavaScript libraries (i.e., jQuery, Prototype, etc.).

SWFUpload is differentiated from other Flash based upload tools by the philosophy behind its design. SWFUpload gives developers control by leaving the UI in the browser. Developers can use HTML, CSS, and JavaScript to tailer the upload UI to the needs and style of their site. Upload status updates are made through a set of simple JavaScript events. The developer uses these events to update the webpage as need for their site.
