The HTML novalidate attribute

Attribute All modern browsers Updated
Quick answer

The HTML novalidate attribute disables the browser's built-in validation when the form is submitted. It is used on the <form> element.

Overview

The novalidate attribute skips native form validation on submit. It is used on the <form> element.

It is a <form>-level attribute that controls how the form is submitted — where the data goes, the HTTP method, how it is encoded, and whether the browser validates first.

Syntax

<form novalidate> … </form>

Values

Value
A boolean attribute — present or absent.

Best practices

  • Use method="post" for submissions that change data and method="get" for searches and filters.
  • Set enctype="multipart/form-data" when the form uploads files.
  • Prefer native validation over novalidate; only skip validation deliberately.
  • Always process and re-validate the submission on the server.
