Google continues to use HTML5 to push its web apps into the future. The latest bit of HTML5 to feel Google’s love is drag-and-drop support, which is now a standard part of Gmail.

But even sites that use a simple HTML button with no special JavaScript coding can still accept files through this drag-and-drop method.

The HTML5-powered webapp will then give you a window to which you can drag and drop any files you want, and they'll automatically appear on your phone, ready for use.
