High definition at about half the file size of 1080p. Roughly 5 to 8 MB per minute, which is usually small enough to send without compression.
Save any public X video at 1280 by 720, straight from the source with nothing re-encoded. High definition at about half the file size of 1080p. Roughly 5 to 8 MB per minute, which is usually small enough to send without compression. The resolution list on each post is read from the post itself rather than from a fixed menu, so what you are offered is what genuinely exists. Below: when 720p HD is the right choice, how it compares to the other options, and why a video sometimes has no 720p HD version at all.
720p HD means 1280 by 720 pixels. It suits phone screens, sending over a messaging app, or saving space on a full device.
Roughly 5 to 8 MB per minute, which is usually small enough to send without compression. That number moves with how much the clip is moving: a static talking head compresses far better than a fast pan or a sports clip, so two videos of the same length at the same resolution can differ in size by a factor of three.
Most X videos top out at 1080p, which is the ceiling for ordinary uploads. 720p halves the file size and is genuinely difficult to distinguish on a phone-sized screen, which makes it the sensible default when you are saving over mobile data. 480p exists for slow connections and for archiving many clips without filling a drive.
The difference is easiest to see on a large screen and hardest to see on a small one. If you plan to edit the clip, or put it on a television, take the highest resolution offered. If you are watching it once on a phone, the smaller file is usually the better trade.
The list of resolutions comes from the post, not from a menu. If a video was uploaded at 720p, there is no 1080p version of it anywhere, and the option will not appear.
This is the point where most downloaders quietly upscale instead, offering a 1080p or even 4K button that stretches a smaller video to fit. The result is a bigger file with no extra detail, because the missing pixels are invented rather than recovered. That is not something this tool does. If 720p HD is offered on a post, it exists in the original.
You get an MP4 holding H.264 video and AAC audio, which is the same file X serves to its own apps. It is copied rather than converted, so there is no second generation of compression loss and no watermark added on the way through.
X itself re-encodes everything uploaded to it, so the source already sits one generation below whatever the poster originally recorded. No downloader can undo that. What a downloader can do is avoid making it worse, and copying rather than re-encoding is how.
The process is identical on mobile. Copy the post link from the X app with the share button, open this page in your browser, and paste it. On iPhone and iPad the file lands in the Files app under Downloads, ready to move into Photos. On Android it goes to the Downloads folder and generally appears in Gallery or Google Photos soon after.
At 720p HD, file size is worth a thought on mobile data. Roughly 5 to 8 MB per minute, which is usually small enough to send without compression. If you are on a metered connection, dropping one step down the list will roughly halve that.
Saving a public video to watch offline, to keep a copy of something you posted, or to quote under fair use is ordinary use. This tool only ever reads what is already public, and keeps no copy once your download finishes.
Redistribution is where it changes. The person who posted the video owns it, and downloading at any resolution does not transfer that. Re-uploading someone else’s work as your own is a copyright problem no matter how the file was obtained.

Choose 720p HD from the list if the post contains it, and the file saves to your device.
