The HTMLFormElement.enctype property is the MIME type of content that is used to submit the form to the server. Possible values are:

  • application/x-www-form-urlencoded: The initial default type.
  • multipart/form-data: The type that allows file <input> element(s) to upload file data.
  • text/plain: A type introduced in HTML5.

This value can be overridden by a formenctype attribute on a <button> or <input> element.
