Live wallpaper maker

Two halves: produce a clean looping video, then hand it to whatever your device uses for moving backgrounds. The first half happens on this page. The second half depends entirely on the device, and that is where most guides go wrong by pretending there is one answer.

iPhone does not take a plain MP4 as a wallpaper. Its moving-wallpaper format is the Live Photo, so the route is: convert the MP4 to a Live Photo with a converter app, save it into Photos, then set it as your lock screen wallpaper with the motion option switched on. Apple has moved that toggle around between iOS releases and has changed more than once which screens will animate, so look for the motion control inside the wallpaper editor on your own version rather than following a fixed menu path from an old tutorial.

Android has no single answer, because it depends on the manufacturer's skin. On some phones the gallery or the launcher will set a video as a live wallpaper straight from the share menu. Where it will not, a video-live-wallpaper app from the Play Store wraps an MP4 into a proper live wallpaper for you. Check what your own gallery offers before installing anything.

Windows has no built-in animated desktop background. A third-party desktop wallpaper utility does the job — Lively Wallpaper is free and open source and takes an MP4 directly. macOS ships its own dynamic and aerial wallpapers but gives you no supported way to point the desktop at your own video file; the workarounds are a third-party desktop-video utility, or a tool that draws a web page on the desktop aimed at a tiny local HTML file holding a looping video element. Treat the macOS route as tinkering rather than a setting.

Everything else is easier than the phones. Digital picture frames, smart displays, TVs with a USB media player and most signage boxes just want the file plus repeat turned on, which is precisely the case a seamless loop was built for.

Upload the largest copy of the photo you have. The model works from what you give it, and detail you throw away before uploading is not coming back.

What comes out is a 6-second clip in 16:9 landscape, and the animation step renders at 480p — so treat the result as standard definition. That is a good match for a TV, a digital frame, a tablet, a desktop that is not 4K, or a phone lock screen where it gets scaled down anyway. Stretched across a large high-density display you will see softness. Being straight about that is more useful than promising 4K we do not produce.

For a portrait phone wallpaper you will need to crop the sides off a landscape frame in any video editor, and there is not a lot of resolution to spare when you do. If you want it crisp, upscale the MP4 first. Composition helps too: keep the subject away from the extreme edges, because clocks, widgets and notification shades eat the top and bottom of a phone screen, and a centred composition survives that crop far better.

Six seconds is the right length for this job, not a compromise. A wallpaper loop is not something you watch once — it is something your eye samples fifty times a day, so a short file that stays cached costs less power and less decoding than a long timeline, and there is no plot to get bored of.

A wallpaper is the most punishing place to put a video, because you see it dozens of times a day and your eye learns the rhythm. Any hitch where the clip restarts becomes impossible to un-notice.

That is the specific problem this tool solves. The generated motion is mirrored back on itself, so the final frame is pixel-identical to the first. When the player wraps around there is nothing to see — no fade, no stutter, no jump. The seamless loop video generator page explains the construction in more detail if you want the mechanics.

Anything atmospheric: mountains under moving cloud, ocean and shoreline, rain against glass, a fog-filled forest, city lights at night, a fireplace, falling snow. Anime and illustrated art also animate nicely, because the model can move the sky and the effects without having to keep a real face consistent.

The one hard constraint comes from the mirroring: motion with a clear direction — someone walking, a car crossing frame — visibly runs backwards in the second half. Ambient motion looks identical either way, which is why weather and water are the sweet spot. The same rule drives the cinemagraph generator, and the general image to loop video tool if you want the loop without the wallpaper advice.
