Want to change the wallpaper on your iPhone? Changing the wallpaper on your home screen is an easy thing to do. You can also select separate images for both your home screen and lock screen, or use the same for both.
1) Open Settings on your iPhone
Go to Settings, tap Wallpaper, then tap Choose a New Wallpaper. You can also turn on Dark Appearance Dims Wallpaper so that your iPhone dims your wallpaper depending on your ambient light.
2) Choose an image
Choose an image from Dynamic, Stills, Live, or one of your photos. The default wallpapers change with each iOS update. iPhone XR and iPhone SE (1st and 2nd generation) don't support Live Wallpaper.
3) 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. When you're done adjusting the image, tap Set. Or tap Cancel to start over.
4) 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.
