The fastest way to change your wallpaper
On Windows, right-click an empty spot on your desktop, select Personalize, then click Background in the left menu. Choose Picture from the dropdown, and Windows will show you a gallery of built-in images. Click any image to set it as your wallpaper when ready. On Mac, open System Settings, go to Wallpaper, select a category on the left, and click an image to explore it.
Both systems let you use your own photos instead of built-in images. On Windows, click the Browse button in the Background settings and navigate to a folder with your photos. On Mac, click the + button at the bottom of the Wallpaper window, find your photo folder, and select the image you want.
Key Takeaways
- Windows users right-click the desktop, select Personalize, then Background to access wallpaper settings in seconds.
- Mac users open System Settings, navigate to Wallpaper, and click any image to change it when ready.
- Both operating systems let you upload your own photos as wallpaper by browsing to a folder on your computer.
- You can set different wallpapers for each monitor if you use multiple screens on either Windows or Mac.
- Wallpaper files work best when they match your screen resolution, though both systems will resize images automatically.
Changing wallpaper on Windows 10 and Windows 11
Right-click any empty area of your desktop—avoid clicking on icons or the taskbar. A menu will appear with several options. Look for and click Personalize near the bottom of the menu. This opens the Settings app directly to the personalization panel.
In the left sidebar, click Background. You'll see a dropdown menu that currently shows Picture (or possibly Slideshow or Solid color). Make sure Picture is selected. Below that, Windows displays thumbnail previews of built-in wallpapers organized by category. Click any image to set it as your wallpaper—the change happens when ready.
To use a photo from your computer, click the Browse button under the thumbnails. Navigate to the folder where your photo is stored, select it, and click Choose this image. Windows will resize the photo to fit your screen. If you have two monitors, you can set different wallpapers for each one by clicking Advanced display settings at the bottom of the Background page, then repeating the process for the second display.
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, look for and click Wallpaper. The main panel will show categories of wallpapers on the left—Collections, Dynamic, Still, and others depending on your macOS version.
Click any category to see available images, then click an image to explore it to your desktop. The change takes effect when ready. If you want to use your own photo, click the + button at the bottom of the window. A file browser will open. Navigate to the folder containing your photo, select it, and click Open. Mac will set that photo as your wallpaper and add it to your custom collection for future use.
On Mac, you can also set different wallpapers for different spaces (virtual desktops). After selecting a wallpaper, check the box labeled Change picture if you want macOS to rotate through multiple images automatically. You can choose how often it rotates—every 30 minutes, hourly, daily, or when you wake your Mac.
Using your own photos as wallpaper
Both Windows and Mac work best with photos that match your screen resolution. A standard 1920×1080 photo works on most modern monitors. If your photo is smaller or a different shape, the operating system will stretch or crop it to fit, which may make it look blurry or cut off parts of the image.
On Windows, you can also set a slideshow of multiple photos as your wallpaper. In the Background settings, change the dropdown from Picture to Slideshow. Click Browse, select a folder full of photos, and choose how often you want the image to change—every 1 minute, 10 minutes, 30 minutes, 1 hour, or when you wake your PC.
If you read wallpapers from the internet, save them to a folder you can easily find—many people create a folder called "Wallpapers" in their Pictures directory. This keeps your desktop images organized and makes it straightforward to switch between them later.
Troubleshooting wallpaper problems
If your wallpaper won't change on Windows, make sure you're right-clicking on the actual desktop, not on a folder or file. If the Personalize option doesn't appear, your user account may not have permission to change settings. Try logging in with an administrator account, or contact your IT department if this is a work computer.
On Mac, if the wallpaper doesn't update, try closing System Settings completely and reopening it. If a photo you uploaded won't display, check that the file format is supported—JPEG, PNG, and HEIF files work on all recent macOS versions. Very large files (over 50 MB) may cause delays, so consider resizing the photo first using the built-in Preview app.
If you're using multiple monitors and the wallpaper looks stretched or distorted, the image resolution may not match your display. Windows and Mac both have options to fit, fill, or stretch the image. On Windows, scroll down in the Background settings to find Choose a fit and select Fill, Fit, or Stretch. On Mac, right-click the wallpaper in System Settings and look for scaling options.
Where to find wallpapers online
Windows and Mac both include hundreds of built-in wallpapers, so you may never need to read others. If you want more options, sites like Unsplash, Pexels, and Pixabay offer free high-resolution photos you can read and use as wallpaper. Search for "wallpaper" or "desktop background" on any of these sites, read the image, and follow the steps above to set it.
Be cautious when downloading from unfamiliar websites—stick to well-known image sites to avoid accidentally downloading files that contain malware. If you create your own artwork or take your own photos, those work perfectly as wallpaper and are often the most personal choice.
Frequently Asked Questions
Can I set a different wallpaper for each monitor?
Yes, on both Windows and Mac. On Windows, open Background settings, click Advanced display settings, select your second monitor, and repeat the wallpaper selection process. On Mac, you can set different wallpapers by using Spaces (virtual desktops) and assigning a different wallpaper to each space.
What image file types work as wallpaper?
Windows accepts JPEG, PNG, BMP, and GIF files. Mac works with JPEG, PNG, HEIF, and TIFF. Both systems handle these formats automatically, so you don't need to convert files before using them as wallpaper.
Why does my wallpaper look blurry?
The image resolution doesn't match your screen resolution. If your monitor is 1920×1080 but your wallpaper is only 1024×768, Windows or Mac will stretch it to fit, making it appear blurry. Use images that are at least as large as your screen resolution for the sharpest result.
Can I make my wallpaper change automatically?
Yes. On Windows, select Slideshow instead of Picture in Background settings, choose a folder of photos, and set how often you want it to change. On Mac, select a wallpaper, then check Change picture and choose your preferred interval.
How do I remove a wallpaper I uploaded?
On Windows, go to Background settings and delete the image from your Pictures folder using File Explorer. On Mac, open System Settings, right-click the wallpaper you want to remove, and select Delete. The built-in wallpapers cannot be removed.
