What Is a Live Photo on iPhone? (And Using It as Wallpaper)

A Live Photo is a 1.5-second animated image captured by iPhone — a HEIC still image paired with a short MOV video, stored together as one file. When you press and hold a Live Photo in the Photos app, or raise your iPhone to wake it from the lock screen, the image briefly comes to life.

How Live Photos Work Technically

Every Live Photo consists of exactly two files:

A HEIC still image — the primary photo you see as a thumbnail (see the HEIC format explainer)
A MOV video clip — 1.5 seconds of footage (0.75 seconds before and 0.75 seconds after the shutter tap) recorded at 15 fps

Both files share the same filename root and are linked by a metadata tag (PHAssetMediaSubtypePhotoLive) — the structure of Apple's native Live Photo format. iOS treats them as a single asset in Photos. If you export just the HEIC, you get a still image. You need both files together to preserve the animation.

Storage size depends on resolution, but a typical Live Photo from an iPhone 15 Pro runs approximately 8–12 MB total compared to 3–5 MB for a standard HEIC still — roughly 3–4 MB of extra storage per photo.

That HEIC + MOV pairing is exactly what a plain JPEG or screenshot is missing. Lockimate builds both halves with AI so any still photo becomes a genuine Live Photo iOS accepts — no camera reshoot needed.

Which iPhones Support Live Photos

Live Photos were introduced with the iPhone 6S in September 2015, running iOS 9. Every iPhone model released since then supports capturing Live Photos:

iPhone 6S / 6S Plus — first Live Photo support, iOS 9+
iPhone 7 through iPhone 15 series — all models, full Live Photo capture
iPhone XS and later — lock screen Live Photo wallpaper support (requires iOS 16+ for full lock screen customization)

The camera app shows a Live Photo icon (concentric circles) in the top center. Tap it to toggle Live Photos on or off per session. The setting does not persist — it resets to your default each time you open the Camera app.

Live Photo Effects

iOS includes 4 built-in effects you can apply to any Live Photo inside the Photos app:

Live — the default 1.5-second play on press
Loop — the clip plays forward repeatedly, like a GIF
Bounce — the clip plays forward then reverses, like a Boomerang
Long Exposure — simulates a slow-shutter photograph by blending all frames into one still image

To change the effect, open the Live Photo in full screen, swipe up to reveal effects, and tap the one you want. Effects are non-destructive and can be changed at any time.

Live Photo vs Other Animated Formats

Format	File type	Duration	File size	Lock screen wallpaper
Live Photo	HEIC + MOV	1.5 sec	~8–12 MB	Yes (iPhone XS+, iOS 16+)
Boomerang	MP4	2–3 sec	~1–3 MB	No
GIF	GIF	Variable	~2–20 MB	No
Video	MOV / MP4	Any	Variable	No (not native)

The critical difference: Live Photo is the only format that animates natively on the iPhone lock screen on raise-to-wake without any workaround. GIFs, videos, and Boomerangs cannot be set as Live lock screen wallpapers — which is also why a live wallpaper differs from a Live Photo.

How to Set a Live Photo as Your Lock Screen Wallpaper

To use a Live Photo as an animated lock screen:

Open Settings → Wallpaper → Add New Wallpaper
Tap Photos and select your Live Photo
Make sure the Live button (bottom left) is highlighted in yellow
Tap Add → Set as Lock Screen

The wallpaper animates each time you raise your iPhone to wake it, press the side button, or tap the screen. This requires iPhone XS or later running iOS 16 or newer. For the full walkthrough, see how to set a Live Photo as your lock screen, and if you only have a still image, turn a photo into a Live Photo.

If you open Photos first and tap Share → Use as Wallpaper, the same Live toggle appears. The toggle only shows up for genuine Live Photos — files with both the HEIC and MOV component linked correctly.

How Lockimate Creates Live Photos from Still Images

Not every photo in your library is a Live Photo. If you have a standard JPEG or HEIC still — a screenshot, a photo from another camera, a downloaded image — it has no MOV component and cannot animate on the lock screen.

Lockimate solves this. It takes any still photo, generates a 1.5-second animation using AI (choosing from vibes like Warm, Cinematic, Playful, or Lively), and exports a properly linked HEIC + MOV pair to your Photos library. The result is a real, native Live Photo that passes iOS's format check and shows the Live toggle when you go to set it as a wallpaper.

The first wallpaper generation is free. Pro unlocks unlimited generations and additional art styles: Anime, 3D Cartoon, and Painterly alongside the default Realistic style.

FAQ

How big are Live Photos on iPhone?

A Live Photo from iPhone 15 Pro Main Camera (48 MP) typically takes up 10–14 MB — about 3–5 MB more than the equivalent HEIC still. On older models like iPhone 12 (12 MP), expect 5–8 MB per Live Photo. Over a library of 1,000 Live Photos, that is roughly 4–6 GB of extra storage compared to shooting stills.

Can I turn off Live Photos permanently?

Not via a single toggle in Settings, but you can make "off" the default. Open Settings → Camera → Preserve Settings, then enable Live Photo. After that, if you turn off Live Photos in the Camera app, it stays off until you turn it on again. The setting preserves your last-used state each time you open Camera.

How do I see Live Photos move?

Three ways: press and hold the photo in the Photos app, raise your iPhone while the Live Photo is displayed on the lock screen (requires Live toggle set in wallpaper settings), or open the photo full screen and tap the Live badge in the top-left corner. On a Mac, hover over the Live Photo in Photos to trigger playback.
