Safari and some devices in Low Power Mode often block background video autoplay, replacing it with a play button. This behavior is intentional due to battery-saving policies and cannot be fully overridden using standard Webflow settings. However, there are a few workarounds you can try using custom code.
1. Understand Safari and Low Power Mode Limitations
- Autoplay is restricted for videos with audio, or if the browser/device is in Low Power Mode, and Apple does not allow autoplay in those conditions.
- Safari requires the video to be muted for autoplay to work. Even muted videos may be paused in Low Power Mode.
2. Use Webflow’s Background Video Element Correctly
- Place your video using the native Background Video element.
- Ensure your video is muted, looping, and optimized in both size (under 30MB) and format (ideally
.mp4). - Webflow automatically sets the video to muted, loop, and autoplay — but autoplay cannot be forced in all environments.
3. Use Custom Code to Enhance Behavior
You can attempt to simulate autoplay behavior using JavaScript, though this won't override power-saving policies:
- Add this in the Page Settings > Footer Section:
<script>
document.addEventListener("DOMContentLoaded", function () {
var videos = document.querySelectorAll("video");
videos.forEach(function (video) {
video.muted = true;
video.playsInline = true;
var playPromise = video.play();
if (playPromise !== undefined) {
playPromise.catch(function () {
// Fallback: user interaction may be required to play
});
}
});
});
</script>
- This code attempts to programmatically trigger video playback when the page loads.
- Note: This won’t work if the browser actively blocks autoplay (e.g., Low Power Mode or Data Saver mode). It handles only edge cases like videos marked incorrectly.
4. Provide a Fallback for Unsupported Scenarios
- If autoplay fails, consider adding a still image with a background gradient or animation behind the video that matches its look.
- You can visually layer a background image and the video so it degrades gracefully.
- Alternatively, add a custom play button with styling to match your site design if autoplay doesn’t work.
Summary
You can’t force autoplay in Safari or Low Power Mode due to system-enforced restrictions. However, you can use muted video, custom JavaScript fallback code, and graceful degradation (like still image background) to handle these edge cases effectively.
