The HTML muted attribute

Attribute All modern browsers Updated
Quick answer

The HTML muted attribute silences the media's audio by default. It is used on the <audio> and <video> elements.

Overview

The muted attribute mutes the media by default. It is used on the <video>, <audio>, <source> and <track> elements.

It configures native audio or video playback — the source, controls, autoplay and looping behavior, the poster image, and text tracks. It works with the <video>/<audio> elements and their nested <source> and <track> children.

Syntax

<video src="clip.mp4" autoplay muted></video>

Values

Value
A boolean attribute — present or absent.

Best practices

  • Provide controls so users can play, pause and seek.
  • Browsers only allow autoplay when the media is also muted.
  • Always add captions with a <track> for accessibility.
  • Offer multiple formats with nested <source> elements for broad support.
