The HTML loop attribute

Attribute All modern browsers Updated
Quick answer

The HTML loop attribute restarts the media from the beginning when it reaches the end. It is used on the <audio> and <video> elements.

Overview

The loop attribute replays media from the start when it ends. 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" loop 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.
