Open Settings on your iPhone
Go to Settings, tap Wallpaper, then tap Choose a New Wallpaper.
Choose an image
Choose an image from Dynamic, Stills, Live, or one of your photos. The default wallpapers change with each iOS update.
To choose a Live wallpaper or a Live Photo, you need an iPhone 6s or later.
iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XR, and iPhone SE don't support Live Wallpaper.
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.
You can choose Perspective, so the wallpaper moves as you tilt your screen. Or you can choose Still, so the wallpaper doesn't move. The Perspective display option isn't available when Reduce Motion is on or when Low Power Mode is on.
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. You can also turn on Dark Appearance so that your iPhone dims your wallpaper depending on your ambient light. Go to Settings > Wallpaper, then select Dark Appearance Dims Wallpaper to turn it on.
To see your new wallpaper, lock your iPhone or check the Home screen.
