You can change the iPhone wallpaper from Settings or directly from the Lock Screen. Current versions of iOS let you customize the Lock Screen and Home Screen together or give each one a different image.
How to Change Your iPhone Wallpaper in Settings
- Open Settings.
- Tap Wallpaper.
- Tap Add New Wallpaper.
- Choose a photo or one of Apple’s wallpaper categories.
- Adjust the image and any available Lock Screen options.
- Tap Add.
- Choose Set as Wallpaper Pair to use the coordinated design, or customize the Home Screen separately.
Change a Wallpaper from the Lock Screen
While the iPhone is unlocked, touch and hold the Lock Screen to open the wallpaper gallery, then choose an existing wallpaper or add a new one. This is also where you can switch between saved Lock Screen designs.
Use a Different Home Screen Background
After creating a Lock Screen, choose the Home Screen customization option if you want a different photo, color, gradient, or blur effect behind your apps.
If a Photo Does Not Fit Correctly
Pinch and drag the photo while editing the wallpaper. The amount of repositioning available depends on the image and the wallpaper layout. A photo with extra space around the subject usually gives you more flexibility.

Open Settings > Wallpaper > Add New Wallpaper to choose a new iPhone background. You can use a coordinated Lock Screen and Home Screen or customize the Home Screen separately.
