The fastest way to change your wallpaper

On Windows, right-click any empty space on your desktop, select Personalize, then click Background. Choose a photo from your computer or pick one of the built-in options, and it appears when ready. On Mac, open System Settings, go to Wallpaper, select a category on the left, click any image, and it changes at once.

Both methods take under a minute. You do not need to restart your computer or install anything. The wallpaper stays until you change it again.

Key Takeaways

  • Windows users right-click the desktop, select Personalize, then Background to pick a new wallpaper in seconds.
  • Mac users open System Settings, navigate to Wallpaper, and click any image to set it as their background.
  • You can use your own photos by uploading them from your computer instead of choosing built-in options.
  • Both operating systems let you set different wallpapers for multiple monitors or schedule wallpapers to change automatically.
  • Wallpaper changes do not affect your files, programs, or computer performance.

Changing wallpaper on Windows 10 and Windows 11

Right-click any blank area of your desktop — avoid clicking on icons or the taskbar. A menu appears with several options. Click Personalize near the bottom of the menu.

The Settings window opens. On the left side, you will see Background listed under Personalization. Click it. A panel on the right shows your current wallpaper and a dropdown menu that says Personalize your background. This dropdown is set to Picture by default.

Below the dropdown, you see thumbnail images of wallpapers Windows includes. Click any one to preview it on your desktop. The change happens when ready. If you like it, close the Settings window and you are done. If you want to try another, click a different thumbnail.

Using your own photos as wallpaper on Windows

In the same Personalize menu, under Background, look for a button labeled Browse. Click it to open your file explorer. Navigate to the folder where your photos are stored — usually Pictures in your user folder. Select the photo you want and click Choose picture.

The photo appears on your desktop right away. If the image is smaller than your screen, Windows stretches it by default. To change how it fits, look for a dropdown in the Background settings that says Choose a fit. Your options are Fill (stretches the image), Fit (shows the whole image with black bars if needed), Stretch (distorts the image to fill the screen), Tile (repeats the image), and Center (places the image in the middle without resizing).

Changing wallpaper on Mac

Click the Apple menu in the top-left corner and select System Settings. In the sidebar on the left, scroll down and click Wallpaper. The main panel shows categories of wallpapers — Collections, Recent, and Favorites appear at the top.

Click any category to see the wallpapers inside it. When you click an image, it becomes your wallpaper when ready. You do not need to confirm or save. Close System Settings and the change stays in place.

If you want to use a photo from your computer, click the + button at the bottom of the wallpaper list. Navigate to your photo, click it, and select Choose. The photo is added to your wallpaper options and set as your background.

Setting different wallpapers for multiple monitors

On Windows, if you have two or more monitors connected, you can set a different wallpaper on each one. Open Personalize and Background as usual. When you click a wallpaper thumbnail, a small menu appears asking which monitor to explore it to. Select the monitor you want and click the image. Repeat for each monitor.

On Mac, the same wallpaper appears on all connected monitors. You cannot set different wallpapers per monitor in System Settings. If you need different backgrounds on each display, third-party apps like Patterned or Wallpaper Wizard offer this feature, though they are not built into macOS.

Scheduling wallpapers to change automatically

On Windows 11, open Personalize and Background. Under Personalize your background, change the dropdown from Picture to Slideshow. Click Browse to select a folder full of photos. Windows will cycle through them at an interval you set — choose from every minute to every day.

On Mac, open System Settings and Wallpaper. Select a category like Collections or Dynamic. Some categories, such as Dynamic, change throughout the day automatically. For a custom slideshow, click the + button, select a folder of photos, and macOS will rotate through them. You can set the change interval in the same menu.

Troubleshooting wallpaper problems

If your wallpaper does not change after you select a new one, close the Settings window completely and wait a few seconds. Sometimes the desktop needs a moment to refresh. If it still does not appear, restart your computer.

If you cannot find the Personalize option on Windows, make sure you right-clicked on an empty part of the desktop, not on a folder, file, or icon. If you are using a work computer, your IT department may have locked wallpaper settings. Contact them to request a change.

On Mac, if the wallpaper does not update, make sure you are in System Settings and not System Preferences — older Macs use Preferences, while newer ones use Settings. If you are still stuck, restart your Mac and try again.

Frequently Asked Questions

Can I use a video as my wallpaper?

Windows 11 does not support video wallpapers natively. Mac does not either. Both systems only accept still images. Some third-party apps like Lively Wallpaper on Windows let you use animated backgrounds, but they require separate installation.

Will changing my wallpaper slow down my computer?

No. Wallpaper is a static image that uses almost no processing power or memory. Changing it does not affect your computer's speed or performance, even if you change it many times a day.

What image size works best for wallpaper?

The best size matches your monitor's resolution. For a standard 1920 by 1080 screen, use an image that is at least 1920 by 1080 pixels. Larger images work fine — Windows and Mac will scale them down. Smaller images may look blurry if stretched to fill the screen.

Can I set a different wallpaper for each user account?

Yes. Each user account on Windows and Mac has its own wallpaper setting. When you log in to your account and change the wallpaper, it only affects that account. Other users see their own wallpapers when they log in.

How do I remove a wallpaper I added?

On Windows, open Personalize and Background, right-click the wallpaper thumbnail you want to remove, and select Delete. On Mac, open System Settings and Wallpaper, find the image in your custom list, click it, and select the trash icon that appears. Built-in wallpapers cannot be deleted.
