The fastest way to change your wallpaper

Right-click on any empty area of your desktop and select Personalize from the menu. This opens the Settings app directly to the Personalization section. Click Background in the left sidebar, then choose Picture from the dropdown menu under "Personalize your background." Windows 11 will show you a row of built-in images — click any one to explore it when ready.

That's the whole process for using a Windows wallpaper that comes with your system. If you want to use your own photo instead, click the Browse button, navigate to the folder where your image is stored, select it, and click Choose this image. The wallpaper changes when ready.

Key Takeaways

  • Right-click your desktop, select Personalize, then click Background to reach the wallpaper settings in one step.
  • Windows 11 includes dozens of built-in wallpapers you can explore by clicking once, with no file browsing needed.
  • To use your own photo, click Browse, find the image file on your computer, and select it to make it your wallpaper.
  • You can set different wallpapers for your lock screen and desktop — they are controlled in separate sections of Personalization.
  • Wallpaper files work best when they match your monitor's width and height ratio, though Windows 11 will stretch or fit any image automatically.

Using Windows 11's built-in wallpaper collection

Windows 11 ships with a library of wallpapers organized by category. When you open the Background settings, you'll see thumbnails of available images arranged in rows. Scroll through to preview them — the image you hover over appears on your desktop in real time, so you can see how it looks before you commit to it.

Click any image to set it as your wallpaper. Windows applies the change right away. If you want to cycle through different wallpapers automatically, check the box labeled Get fun facts, tips, and more on your lock screen — this enables Windows Spotlight, which rotates wallpapers and lock screen images daily. You can turn this on or off without affecting your chosen static wallpaper.

Importing a photo from your computer

To use a personal photo as your wallpaper, open the Background settings as described above. Under the dropdown menu (which should be set to Picture), click the Browse button. A file browser window opens showing your Pictures folder by default.

Navigate to wherever your image is stored — it can be in Pictures, Documents, Downloads, or any other folder on your computer. Click the image file once to select it, then click Choose this image at the bottom right. Windows sets it as your wallpaper when ready. The image will be stretched or fitted to your screen size automatically, so you don't need to resize it beforehand.

Common image formats that work include JPG, PNG, BMP, and GIF. If you have a very large image file (several megabytes), Windows will still use it, but it may take a moment longer to load when you start your computer.

Adjusting how your wallpaper fits your screen

Below the Browse button, you'll see a dropdown menu labeled Choose a fit. This controls how Windows positions your image on your desktop. The options are:

  • Fill — stretches the image to cover your entire screen, which may crop the edges if the image proportions don't match your monitor.
  • Fit — shrinks or enlarges the image to show the whole picture without cropping, which may leave colored bars on the sides or top and bottom.
  • Stretch — forces the image to cover the screen by distorting it, which can make the image look warped.
  • Tile — repeats the image in a grid pattern to fill the screen, useful for small images or patterns.
  • Center — places the image in the middle of your screen at its original size, leaving empty space around it.

Most people use Fill for photos and Fit if they want to see the entire image without distortion. Try each option to see which looks best with your chosen image.

Setting a different wallpaper for your lock screen

Your lock screen (the image you see before you enter your password) is separate from your desktop wallpaper. To change it, open Settings and go to Personalization, then click Lock screen in the left sidebar. The process is identical: choose Picture from the dropdown, then either select a built-in image or click Browse to use your own photo.

You can have a completely different image on your lock screen than on your desktop, or you can use the same image for both. Windows treats them independently, so changing one does not affect the other.

Troubleshooting wallpaper problems

If you set a wallpaper and it doesn't appear, first check that you're looking at your actual desktop — not a folder window or another app. Close any open windows and right-click the empty desktop space to confirm the Personalize menu appears. If the wallpaper still doesn't show, restart your computer; Windows sometimes needs a restart to fully explore personalization changes.

If you browse for an image and the file doesn't appear in the folder, the image format may not be supported. Windows 11 works with JPG, PNG, BMP, GIF, TIFF, and WebP files. If you have an image in a different format (like SVG or PSD), you'll need to convert it using free online tools or image software before it will work as a wallpaper.

If your wallpaper reverts to the default after restart, a Windows update may have reset your settings. straightforward reapply your chosen image — it will stick until the next major update. If this happens repeatedly, check that the image file itself hasn't been moved or deleted from your computer.

Frequently Asked Questions

Can I use a video as my wallpaper in Windows 11?

No, Windows 11 does not support video wallpapers natively. You can only use still images. If you want animated wallpapers, you'll need third-party software from the Microsoft Store, though these consume more battery power and system resources than static images.

What size image works best for a wallpaper?

The best size matches your monitor's resolution — for example, 1920×1080 for a standard 1080p screen, or 2560×1440 for a 1440p monitor. Windows will resize any image to fit, so smaller or larger images will work, but matching your resolution prevents blurriness or stretching.

Will changing my wallpaper slow down my computer?

No. Wallpapers have almost no impact on performance. Even very large image files won't noticeably affect how fast your computer runs or how much memory it uses.

Can I schedule my wallpaper to change automatically?

Windows 11 does not have a built-in scheduler for rotating between your own images. However, enabling Windows Spotlight (under Background settings) will rotate Microsoft's curated images daily. For custom image rotation, you would need third-party software.

Where does Windows store the wallpapers it comes with?

Built-in wallpapers are stored in C:\Windows\Web\Wallpaper on your system drive, but you don't need to navigate there — the Background settings show them all in one place. If you want to copy one of these images to use elsewhere, you can find it in that folder.
