The fastest way to change your wallpaper

On Windows, right-click any empty space on your desktop, select Personalize, then click Background in the left menu. Choose Picture from the dropdown, and Windows will show you a folder of built-in images. Click any image to set it as your wallpaper — it changes when ready. On Mac, open System Settings, click Wallpaper in the sidebar, select a category on the left, then click the image you want.

Both systems let you use your own photos instead of built-in images. On Windows, click the Browse button in the Background settings to navigate to a folder on your computer. On Mac, click the + button at the bottom of the Wallpaper window, find your photo, and click Open. The image appears on your desktop within seconds.

Key Takeaways

  • Windows users right-click the desktop, select Personalize, then Background to see built-in wallpapers and change the image when ready.
  • Mac users open System Settings, click Wallpaper, and select from categories or add their own photos using the plus button.
  • Both systems let you browse your computer's folders to use personal photos as wallpaper instead of pre-made images.
  • You can set different wallpapers for each monitor if your PC has multiple displays.
  • Wallpaper changes take effect when ready and do not require restarting your computer.

Changing wallpaper on Windows 10 and Windows 11

The steps are nearly identical on both versions. Right-click any blank area of your desktop — avoid clicking on icons or the taskbar. A menu appears with several options. Look for Personalize near the bottom and click it. Windows opens the Settings app directly to the Personalization section.

On the left side of the window, you will see a menu with options like Background, Colors, and Lock screen. Click Background. Below that, a dropdown menu shows your current setting — usually Picture. Windows displays thumbnail images of built-in wallpapers below the dropdown. Scroll through them and click any image to set it when ready. Your desktop updates without closing the Settings window.

If you want to use a photo from your computer instead, click the Browse button. A file browser opens. Navigate to the folder where your photo is stored — often Pictures in your user folder. Click the image once to select it, then click Choose this image. The wallpaper changes right away.

Changing wallpaper on Mac

Open System Settings from the Apple menu or by clicking the gear icon in your dock. In the sidebar on the left, scroll down and click Wallpaper. The main window shows categories of images — Collections, Dynamic, Light, and Dark are common options. Click any category to see the images inside it.

Click the image you want to use. A preview appears on the right side of the window. If you like it, the wallpaper is already set — Mac applies it when ready to your desktop and lock screen. If you want to use a photo from your computer instead, click the + button at the bottom of the window. A file browser opens. Find your photo, click it once, and click Open. The image becomes your wallpaper right away.

Using your own photos as wallpaper

Both Windows and Mac work best with photos that are at least 1920 pixels wide and 1080 pixels tall — this matches the resolution of most modern monitors. Smaller images may look blurry or stretched. If you are not sure of your photo's size, right-click it in your file browser, select Properties (Windows) or Get Info (Mac), and look for the dimensions.

You can store your wallpaper photos anywhere on your computer, but keeping them in your Pictures folder makes them easier to find later. When you browse for a new wallpaper, Windows and Mac both open to common locations first, so a photo in Pictures will appear quickly.

If you have a photo you downloaded from the internet, make sure you have the right to use it as wallpaper. Photos you took yourself or images marked as free to use are safe choices. Avoid using copyrighted images without permission.

Setting different wallpapers for multiple monitors

On Windows, if your PC has two or more monitors connected, you can set a different wallpaper for each one. Right-click the desktop and open Personalize as usual. In the Background section, look for a dropdown that says Choose a fit or Choose your picture. Below the wallpaper thumbnails, you will see small icons representing each monitor. Click the icon for the monitor you want to change, then select a new image. Repeat for each monitor.

On Mac, the wallpaper applies to all connected displays at once. You cannot set different images for each monitor using the built-in settings. If you need different wallpapers on multiple displays, third-party apps are available, but the standard Mac system does not offer this feature.

Troubleshooting wallpaper problems

If your wallpaper does not change after you select a new image, try closing the Settings window and opening it again. Sometimes the preview does not update when ready, but the wallpaper itself has changed. Look at your actual desktop to confirm.

If an image you selected appears stretched or distorted, the image may be too small for your monitor's resolution. Try a larger photo, or use the Choose a fit dropdown in Windows to select Fill instead of Fit — this crops the image to fill the screen instead of stretching it.

On Windows, if you cannot right-click the desktop, your system administrator may have locked personalization settings. Try opening Settings directly by pressing Windows key + I, then navigating to Personalization and Background. On Mac, if the Wallpaper option does not appear in System Settings, restart your computer and try again.

Frequently Asked Questions

Can I set a video or animated wallpaper instead of a still image?

Windows 11 offers animated wallpapers through the Microsoft Store, but the built-in settings only support still images. You can read third-party apps that add video wallpaper support. Mac does not have a native animated wallpaper feature in System Settings, though some third-party apps provide this.

Will changing my wallpaper slow down my computer?

No. A wallpaper is just an image file displayed behind your desktop icons. It uses almost no processing power or memory. Changing it as often as you like will not affect your computer's speed.

What happens to my wallpaper if I update Windows or Mac?

Your custom wallpaper stays in place after an update. If you used a built-in image, the system may reset to a default wallpaper during a major update, but you can change it back using the same steps.

Can I schedule my wallpaper to change automatically?

Windows has a built-in feature for this. In the Background settings, look for Change picture every and set a time interval — 1 minute, 10 minutes, hourly, or daily. Windows will cycle through images in the folder you selected. Mac does not have this feature in System Settings, but third-party apps can automate wallpaper changes.

Where do I find the built-in wallpapers on my computer?

You do not need to find them — Windows and Mac display them directly in the Personalization or Wallpaper settings. If you want to locate the actual files, Windows stores them in C:\Windows\Web\Wallpaper and Mac stores them in /Library/Desktop Pictures, but you do not need to access these folders to change your wallpaper.
