The fastest way depends on your device

Changing your wallpaper takes less than a minute on any device, but the steps differ. On Windows, right-click the desktop and select "Personalize" or "Customize". On Mac, open System Settings, go to Wallpaper, and drag an image into the preview. On iPhone, open Settings, tap Wallpaper, then "Add New Wallpaper". On Android, long-press the home screen, tap Wallpaper, and choose from your gallery or built-in options.

Each operating system stores wallpapers in a different place and offers different sources — some let you use any photo from your device, others have built-in collections, and some let you download new ones. The method also depends on whether you want to change just the lock screen, just the home screen, or both.

Key Takeaways

  • Windows and Mac let you use any image file from your computer; iPhone and Android offer built-in wallpaper collections alongside your own photos.
  • On Windows, right-click the desktop and choose Personalize; on Mac, use System Settings under Wallpaper.
  • iPhone and Android separate lock screen and home screen wallpapers, so you can set different images for each.
  • If you want a specific image, download it first to your device's photo library before opening the wallpaper settings.

Changing wallpaper on Windows 10 and 11

Right-click anywhere on your desktop background and select "Personalize" from the menu. This opens the Settings app to the Personalization section. On the left sidebar, click "Background" if it is not already selected.

You will see three options under "Personalize your background": Picture, Solid color, or Slideshow. If you choose Picture, click "Browse" to select an image file from your computer. Windows will show you a preview before you confirm. If you want to use one of Windows' built-in images instead, click the dropdown that says "Recent" or "Suggested" and pick from the available collections.

Once you have chosen an image, the wallpaper updates immediately. You can also adjust how the image fits the screen — the "Choose a fit" dropdown lets you pick between Fill, Fit, Stretch, Tile, or Center. Fill is the most common choice and scales the image to cover the entire screen.

Changing wallpaper on Mac

Click the Apple menu in the top-left corner and select "System Settings" (or "System Preferences" on older macOS versions). In the sidebar, click "Wallpaper". You will see thumbnails of available wallpapers organized by category — Dynamic, Still, and Collections.

To use one of Apple's built-in wallpapers, click a category and then click the image you want. To use your own photo, click the "+" button at the bottom of the window, navigate to the image on your computer, and select it. Mac will show you a preview and ask whether you want to apply it to your desktop, lock screen, or both.

If you have multiple monitors, you can set different wallpapers on each one. Just select the monitor from the dropdown at the top of the Wallpaper settings before choosing your image.

Changing wallpaper on iPhone

Open the Settings app and scroll down to find "Wallpaper". Tap it, then tap "Add New Wallpaper" or the "+" button. You will see several options: Featured (Apple's curated collections), Photos (your own images), and sometimes Emoji or other categories depending on your iOS version.

If you choose Photos, select an album and then the specific image you want. iPhone will show you a preview and let you adjust the zoom. When you are ready, tap "Add" and choose whether to apply it to your lock screen, home screen, or both. You can set different wallpapers for each.

iPhone also offers dynamic and live wallpapers in the Featured section. These animate or change based on time of day. They use more battery power than static images, so keep that in mind if you are concerned about battery life.

Changing wallpaper on Android

The exact steps vary by manufacturer — Samsung, Google Pixel, OnePlus, and others have slightly different layouts. The most common method is to long-press (hold your finger on) the home screen until a menu appears at the bottom. Tap "Wallpapers" or "Wallpaper".

You will see options for your wallpaper source: built-in collections, your Photos app, or sometimes third-party wallpaper apps. Select the source, choose your image, and tap "Set wallpaper" or "Apply". Most Android phones let you choose whether to apply it to your home screen, lock screen, or both.

If the long-press method does not work on your phone, try opening Settings, searching for "Wallpaper", and tapping the result. Some Android versions also let you access wallpaper settings through the Display or Home Screen section of Settings.

Using images from the internet

If you want to use an image you found online, download it to your device first. On Windows or Mac, right-click the image and select "Save image as" or "Download image", then choose where to save it. On iPhone, tap and hold the image, then select "Save Image". On Android, long-press the image and tap "Download image" or "Save image".

Once the image is saved to your device, follow the wallpaper-changing steps above and navigate to the folder where you saved it. The image will now appear in your Photos app or file browser and you can set it as your wallpaper.

Be aware that very large image files may take longer to load, and images with unusual dimensions might not fit your screen perfectly. Most devices let you crop or zoom the image before applying it, so you can adjust the framing if needed.

Troubleshooting common problems

If your wallpaper does not change after you select it, try restarting your device. On Windows, you can also try right-clicking the desktop again and selecting "Refresh" to force the system to reload the background. On Mac, try clicking a different wallpaper and then clicking your chosen one again.

If the image looks stretched or distorted, check the "fit" or "zoom" settings. Windows' "Fill" option usually works best for photos. On iPhone and Android, you can pinch to zoom the preview before applying the wallpaper to adjust how much of the image shows.

If you cannot find the wallpaper settings on Android, check whether your phone manufacturer has a custom launcher or settings app. Samsung phones, for example, use "Themes" instead of the standard Android wallpaper menu. Check your phone's manual or support page if the standard steps do not work.

Frequently Asked Questions

Can I use a video as my wallpaper?

Windows and Mac do not support video wallpapers natively, though third-party apps exist. iPhone offers live wallpapers that animate but are not full videos. Android does not support video wallpapers in the standard settings, but some custom launchers and third-party apps provide this feature.

Will changing my wallpaper slow down my computer or phone?

No. A static image wallpaper has no effect on performance. Animated or live wallpapers use slightly more battery on phones, but the impact is minimal unless you use them constantly. On computers, the difference is negligible.

What image size works best for wallpaper?

Match your screen resolution if possible — for example, 1920x1080 for a standard desktop monitor, or 2560x1440 for a higher-resolution display. Your device will scale the image to fit, so exact dimensions are not critical, but larger images generally look sharper than very small ones.

Can I set different wallpapers for different user accounts?

Yes, on both Windows and Mac. Each user account has its own wallpaper setting, so you can customize the background for each person who uses the computer. On phones, only one user account typically exists, so the wallpaper applies to everyone who uses the device.

How do I remove a wallpaper and go back to the default?

On Windows, open Personalize, go to Background, and select "Solid color" or choose one of the default Windows wallpapers. On Mac, open Wallpaper settings and click one of Apple's built-in options. On iPhone and Android, return to the wallpaper settings and select a default option from the Featured or built-in collections.
