To download a video from a tweet (X’s official message for the update still refers to posts as tweets) for offline viewing or to create new content to share, for example, on other platforms, here’s what you need to do: Go to the video you want to download, tap the three dots in the top right corner, and then select “Download video.”
For those who want to opt-out of their videos being downloadable, follow these steps while composing a tweet: After uploading a video, tap “Edit” in the bottom right of the video, then go to “Settings,” and toggle the “Allow video to be downloaded” option on or off.
Keep in mind that once you set this option, it cannot be changed later. If you change your mind in the future, you’ll need to delete the tweet itself to prevent downloads.
