It's not quite clear what you want. But there is in fact a way to upload files without forms (and its POST request method/ctype). It's called a "PUT" request. All major http libraries can do that. Major browsers only via AJAX.

However, the receiving script must have specific support for it. Needs to check $_SERVER[REQUEST_METHOD] and read form php://input, and it really just allowed receiving a single file. It might even be necessary to set it up as Apache handler:
