HTML <video> autoplay Attribute

The autoplay attribute on a <video> tag specifies that the video starts playing immediately when the page is loaded.

Example

#

An autoplay attribute on a <video> element.
Note: to avoid surprises, autoplay is disabled on this page. Click 'Try It live' to see it enabled.

<video width="320" autoplay>
  <source src="/media/movie.mp4" type="video/mp4">
  <source src="/media/movie.ogg" type="video/ogg">
</video>

Using autoplay

The autoplay attribute specifies that the video player starts when the page is loaded.

With this attribute, the video file will start playing even before the entire file is loaded.

Tip: Automatically playing a video may surprise users because they are not expecting it.
It is better to give the users full control over when to start.
