Turn one still into the lock screen that makes your phone feel unmistakably yours: quiet ambient motion, a locked camera, and an endless moment you want to wake the screen to see.

Generated on this page's flow, from one vertical image and one paragraph of instruction. Drop your own still in to see the loop it builds.

Chosen deliberately, because it is the easiest class of subject to loop. Everything in the frame that could move — the drops, the shimmer on the lights — is motion that repeats in reality, so the model does not have to invent an arc. There is no person in it and nothing at the edges waiting to enter, which removes the two commonest ways a loop breaks.
Start from a photo like thisDrops run down and merge, the bokeh behind pulses gently, and the framing does not shift by a pixel. Watch it twice and try to catch the seam — the point of this demo is not to be loud, but to be hypnotic in exactly the right way. That is the property a looping wallpaper needs and an ordinary clip never has.
See it loopSame models, opposite instructions. Most of the craft is in what you tell it not to do.
Image-to-video is tuned to be interesting. Given a still it will invent a camera move, start an action, build to something — all the things that make a five-second clip worth watching once. A phone wallpaper is watched a hundred times a day, so it has to do the opposite: hold still and repeat without a seam.
Two practical notes. What comes back is an MP4, which is what Android wallpaper apps and desktop tools like Lively want directly. On iOS the lock screen takes a Live Photo rather than a video, so convert the MP4 to a Live Photo and set it straight from your photo library.

Start from a vertical still, ask for ambient motion with a locked camera, then check the first and last frames.

Water, weather, fire, crowds at distance, city lights. Anything whose real-world motion repeats will loop without you having to force it, and anything with a beginning and an end will not.
In those words. It is the single instruction that separates a wallpaper from a clip, and a model will add a drift if you leave the door open. Ours keeps the camera locked, adds only ambient motion, and guides the ending back toward the opening so the join disappears into the scene.
Each of these is the opposite of what you would ask for in a normal clip.
Shoot or generate the still at 9:16. Cropping a wide frame afterwards throws away the composition, and a lock screen crops hard around the clock and the notifications.

"The camera is completely locked off and never moves or zooms." Say it in the prompt even though it feels redundant. It is the instruction most likely to be quietly ignored if you only imply it.
Nothing walks in, nothing leaves, no person appears. An object that enters the frame has to leave it before the loop restarts, and it never quite does.

Scrub to the start, then to the end, and compare. If the composition drifted, rerun rather than editing — a wallpaper that jumps every five seconds is the one thing users notice immediately.
Your phone is only the beginning: put quiet motion behind your work, your stream, your event and the post people stop scrolling to watch.

The original reason anyone searches for this. A loop built from a photo you took means a moving wallpaper nobody else has, instead of the same handful of files that ship with the theme apps.

Animated desktop tools take an MP4 straight. The requirement is the same as a phone and the failure is worse — a background that resolves something every few seconds behind your work is genuinely hard to ignore.
A looping plate behind a talking head, on a shop screen, or on a stand at an event. Same discipline, larger canvas, and it pairs with a background plate built for the same eye level.
A still with a little ambient motion outperforms a flat image in a feed without ever looking like an ad. Vertical already, and short enough to autoplay twice before anyone scrolls.
The practical questions between a generated loop and a working lock screen.
iOS wants a Live Photo rather than a video, so there is one conversion step in between. Free apps in the App Store do it — you import the MP4, they output a Live Photo, and you set it from the photo library with Live Photo enabled. Android is more direct: a video live wallpaper app takes the file as it is.
Short. A few seconds is right, because the shorter the clip the less chance the composition has to drift away from where it started. Long loops sound better in theory and are much harder to make seamless in practice.
It loops well rather than mathematically. The prompt drives the end back toward the start, and on ambient subjects the join is usually invisible; on anything with a clear moving object it is not. If the seam bothers you, choosing a more cyclical subject helps far more than another rerun.
An animated lock screen does a little more work than a static one on any phone, and in practice most people find a short, quiet loop unnoticeable next to normal screen-on time.
Rain, water, fog, fire, snow, city lights out of focus, slow crowds at distance. The common factor is motion that repeats in the real world. Portraits are the hardest case, because a face that blinks or turns creates exactly the beginning and end a loop cannot absorb.
Yes, that is the main path — upload the still and describe the ambient motion you want in it. Photos you upload travel over HTTPS, land in your own history and go nowhere else. Every output is AI-generated.
Any plan or pack — even a $19.90 one — unlocks a clean copy of every image you have made here, starts each new run instantly, and refunds one that fails.
