With the video open, tap “Edit” in the upper-right corner of the screen.

With audio enabled, a yellow speaker icon will appear in the upper-left corner of the screen. Tap it to disable the audio.

Unlike other speaker icons in iOS and iPadOS, this is not simply a mute button. Tapping the yellow speaker removes the audio track from the video file itself, so that the video will be silent when you share it.

With the audio for the video disabled, the speaker icon will change to a grayed-out speaker icon with a diagonal strike mark through it.

Tap “Done” to save your changes to the video.

Once the audio is disabled on a particular video, you will see a grayed-out speaker icon on the toolbar in Photos when you are examining the video. This means that the video has no audio component to it.

If the icon looks like a crossed-out speaker in this spot, it could mean that you phone is merely silenced. Turn the sound back on and make sure the speaker icon is fully grayed out before sharing.

Now you’re free to share the video however you wish, and no one will hear any sound when the video plays.

How to Restore the Sound You Just Removed

The Photos app saves the original videos and photos you edit, so you can undo your changes.

After sharing, if you would like to undo the removal of the sound on the video, open “Photos” and inspect the video you’d like to fix. Tap “Edit” in the corner of the screen, then tap “Revert.” The audio for that particular video will be restored.
