Open Settings on your iPhone
Open Settings, tap Wallpaper, then tap Choose a New Wallpaper.
You can also turn on Dark Appearance so that your iPhone dims your wallpaper depending on your ambient light.
Choose an image
Choose an image from Dynamic, Stills, Live, or one of your photos. The default wallpapers change with each iOS update.
Using a Live wallpaper or Live Photo is possible on all models after iPhone 6s except for iPhone XR and iPhone SE (1st and 2nd generation).
Move the image and choose a display option
Drag to move the image. Or pinch to zoom in and out, so the image fits the screen.
Some images might not move and scale.
If Perspective Zoom is on, the wallpaper moves as you tilt your screen. To turn it off, tap the Perspective Zoom button at the bottom of the screen. The Perspective Zoom display option isn't available when Reduce Motion is on or when Low Power Mode is on. If your wallpaper is a Live Photo, you can turn on either the Live Photo effect or Perspective Zoom, but not both at the same time.
When you're done adjusting the image, tap Set. Or tap Cancel to start over.
Set the wallpaper and choose where you want it to show up
You can set the wallpaper as your Home Screen, Lock Screen, or both. The Home Screen appears when your iPhone is unlocked. The Lock Screen appears when you wake your iPhone.
To see your new wallpaper, lock your iPhone or check the Home Screen.
To see your new Live wallpaper in action, touch and hold the Lock Screen.
