The two ways to change your iPhone screen picture

Your iPhone has two separate screens you can customize with pictures: the lock screen (what you see when you pick up your phone) and the home screen (where your apps live). You change each one through the Settings app, and the process takes less than a minute for either.

Both changes start the same way: open Settings, tap Wallpaper, then tap Customize. From there, you choose which screen to change and pick your image. The image can come from your photo library, Apple's built-in wallpaper collection, or a photo you've taken yourself.

If you've never customized your screens before, your lock screen is probably a default Apple image and your home screen shows your apps on a plain background. Changing either one is free and doesn't affect how your phone works.

Key Takeaways

  • Open Settings, tap Wallpaper, then Customize to change either your lock screen or home screen picture.
  • You can use photos from your library, Apple's built-in wallpapers, or photos you've taken yourself.
  • Lock screen and home screen are separate — changing one doesn't change the other.
  • You can set different pictures for different times of day or create a collection that rotates automatically.
  • If a photo looks cropped or positioned wrong, you can adjust it before confirming the change.

How to change your lock screen picture

Start by opening the Settings app and scrolling down to find Wallpaper. Tap it, then tap Customize. You'll see your current lock screen at the top — tap it to change it.

A menu will appear with options: Photos (your photo library), a search icon to find specific photos, and Apple's built-in wallpaper collections like Nature, Astronomy, or Flowers. Choose whichever source has the image you want. If you're using a photo you took, tap Photos and find it in your library.

Once you've picked an image, you can pinch and drag to reposition it or adjust how much of the photo shows. When it looks right, tap Add at the bottom. A new screen will ask whether you want to set this as your lock screen only, your home screen only, or both — choose Lock Screen Only if you only want to change the lock screen.

Tap Set as Wallpaper and you're done. The next time you wake your phone, you'll see your new lock screen picture.

How to change your home screen picture

The home screen process is identical to the lock screen, except you choose Home Screen Only instead of Lock Screen Only at the final step. Open Settings, tap Wallpaper, tap Customize, then tap your current home screen thumbnail (usually shown below the lock screen preview).

Pick your image source, adjust the crop if needed, and tap Add. When the dialog appears asking which screen to set, choose Home Screen Only. Tap Set as Wallpaper and the change takes effect immediately — you'll see your new background behind your app icons.

If your home screen picture makes it hard to read app names, you can add a dark or light tint to it. After you pick your image but before you tap Add, look for a Tint option and adjust the slider. A stronger tint makes text easier to read.

Using Apple's built-in wallpaper collections

Apple includes dozens of free wallpaper sets you don't have to download from anywhere — they're built into every iPhone. When you tap Wallpaper in Settings and choose Customize, you'll see options like Nature, Astronomy, Flowers, Gradients, and Solid Colors.

Each collection has multiple images to choose from. Tap any collection to see what's inside, then tap the image you want. Some collections, like Astronomy, let you customize the image further — for example, you can choose which planet or nebula appears.

These wallpapers are optimized for iPhones, so they look sharp and don't take up much storage space. They're a good choice if you want something polished without hunting through your photo library.

Setting different pictures for different times of day

If you want your lock screen to show one picture during the day and a different one at night, you can create a schedule. After you pick your first image and tap Add, instead of choosing Lock Screen Only, tap Lock Screen. A new screen appears showing your image with a time selector at the bottom.

Tap the time field and set when you want this picture to appear. Then tap Add and repeat the process with a second image, setting it to appear at a different time. Your phone will automatically switch between them based on the times you chose.

This feature works best if you pick images that suit the time of day — a bright photo for morning, a darker one for evening. You can set up as many time-based pictures as you want, though most people use two or three.

Fixing a picture that looks cropped or positioned wrong

When you pick a photo, iOS automatically crops it to fit your screen. If the crop cuts off something important — like someone's face — you can adjust it before confirming. After you tap your image in the Customize screen, you'll see it displayed on a preview of your phone.

Pinch to zoom in or out, and drag to move the image around. The parts you see in the preview are what will actually show on your lock screen or home screen. Adjust until it looks right, then tap Add to continue.

If you realize after setting the wallpaper that the crop is wrong, go back to Settings > Wallpaper > Customize, tap the screen you want to fix, find the same image, and adjust it again. You can change it as many times as you want.

Using photos from your library or camera roll

Any photo you've taken or saved to your iPhone can become a wallpaper. Open Settings, tap Wallpaper, tap Customize, then tap Photos. You'll see your entire photo library organized by date and album.

Scroll to find the photo you want, tap it once to select it, then tap Add. The image will appear on a preview of your phone, and you can adjust the crop and position before confirming. This is useful if you want a family photo, a landscape you took, or any personal image as your background.

If you have a lot of photos, you can search by date or use the search icon to find a specific image faster. Once you've set a photo as your wallpaper, it stays in your library — changing it to a wallpaper doesn't delete it or move it anywhere.

Frequently Asked Questions

Can I use the same picture for both lock screen and home screen?

Yes. After you pick your image and tap Add, choose the option that says "Set Both" or "Lock Screen and Home Screen" instead of choosing one or the other. The same image will appear on both screens.

What if my wallpaper picture looks blurry or pixelated?

This usually happens when you use a photo that's smaller than your screen resolution. Try a different photo, or use one of Apple's built-in wallpapers, which are designed for your phone's screen size. Photos you take with your iPhone camera are almost always large enough.

Can I rotate through multiple pictures automatically?

Yes, but only on the lock screen. After you set your first wallpaper, go back to Settings > Wallpaper > Customize, tap your lock screen, and add more images one at a time, each with a different time schedule. Your phone will cycle through them throughout the day.

Does changing my wallpaper use storage space?

No. Wallpapers are displayed from your photo library or from Apple's built-in collection — they don't create a copy that takes up extra space. The only storage used is the original photo if you took it yourself.

Can I undo a wallpaper change?

Yes. Go back to Settings > Wallpaper > Customize, tap the screen you want to change, pick a different image, and set it. There's no limit to how many times you can change your wallpaper.
