HTML - enctype Attribute

HTML enctype attribute is used to specify how the form input data should be encoded before sending it to the server.

This attribute is used if the value of the method attribute is post and is present within the <form> element. The default value of this attribute is "application/x-www-form-urlencoded".

Syntax

<form enctype = "value"></form>

Following are values of the ‘enctype’ attribute

text/plain: It is used for debugging purposes.
multipart/form-data: It is used if the form contains the <input> element with type = file.
application/x-www-form-urlencoded: It defines that all characters are encoded before being sent.

These values can be overridden by the formenctype attribute on <button>, <input type = submit>, or <input type = image> elements.
