Why won't my video autoplay?

Most browsers restrict autoplay to protect users—especially on mobile.

Common reasons autoplay is blocked

• The video has audio enabled (muted autoplay is far more reliable).
• The browser is in low power mode or has data-saving enabled.
• The video is too large/heavy and doesn't load quickly enough.
• The section is configured for click-to-play behavior.

What to do

1. Ensure the video is muted by default (best practice for storefronts).
2. Keep videos short (6–15 seconds for background loops).
3. Export in a web-friendly format and size so it starts fast.
4. Test on:
   • iOS Safari
   • Android Chrome
   • Desktop Chrome/Safari

Storefront UX guidance

• If the video contains important information, don't rely on autoplay—provide a visible play control.
• Avoid background video with sound. It hurts conversion and user trust.
