WhatsApp works on your computer through an app or a web version

You can use WhatsApp on your computer in two ways: read the desktop app (available for Windows and Mac), or use WhatsApp Web in your browser without installing anything. The desktop app works when your phone is nearby and connected to the internet — it mirrors your phone's messages to your computer screen. WhatsApp Web does the same thing but runs inside Chrome, Firefox, Safari, or Edge instead of as a separate program.

Both methods let you read and send messages, make calls, and share files from your keyboard and monitor. The choice between them comes down to whether you want a dedicated program on your computer or prefer to keep everything in your browser.

Key Takeaways

  • The WhatsApp desktop app for Windows or Mac requires your phone to be online and nearby, but works like any other program on your computer.
  • WhatsApp Web runs in your browser and requires the same phone connection, but does not install anything on your computer.
  • Both methods start by scanning a QR code with your phone to connect your computer to your account.
  • You need an active WhatsApp account on your phone before you can use WhatsApp on your computer.

Installing the WhatsApp desktop app on Windows

Go to microsoft.com/store and search for "WhatsApp" in the Microsoft Store search box at the top. Click the WhatsApp result (the one with the green phone icon), then click the blue "Get" button. Windows will read and install the app automatically — you do not need to choose a folder or confirm installation steps.

Once installation finishes, click "Open" or find WhatsApp in your Start menu and click it. The app will open and show you a QR code on your screen. Pick up your phone, open WhatsApp, tap the three dots menu (Android) or Settings (iPhone), and look for "Linked Devices" or "WhatsApp Web". Tap it, then tap the plus icon or "Link a Device". Point your phone's camera at the QR code on your computer screen and hold it steady for two seconds. Your phone will confirm the connection, and your messages will appear on your computer within a few seconds.

Installing the WhatsApp desktop app on Mac

Open the App Store on your Mac (click the App Store icon in your dock, or search for "App Store" using Spotlight). Search for "WhatsApp" in the search box at the top. Click the WhatsApp result, then click the blue "Get" button. Your Mac will ask you to sign in with your Apple ID — enter your password and wait for the read to finish.

Click "Open" when the installation completes, or find WhatsApp in your Applications folder and double-click it. The app will display a QR code. On your phone, open WhatsApp, go to Settings (iPhone) or tap the three dots menu (Android), find "Linked Devices", and tap the plus icon or "Link a Device". Point your phone's camera at the QR code on your Mac screen. Once your phone confirms the connection, your messages will sync to your computer.

Using WhatsApp Web instead of installing an app

If you do not want to install anything, open any web browser on your computer and go to web.whatsapp.com. You will see a large QR code and instructions on the screen. On your phone, open WhatsApp, go to Settings (iPhone) or tap the three dots menu (Android), find "Linked Devices", and tap the plus icon or "Link a Device". Point your phone's camera at the QR code on your screen.

After your phone scans the code, your messages will load in the browser. WhatsApp Web works exactly like the desktop app — you can send messages, make calls, and share files. The only difference is that it runs in your browser tab instead of as a separate program. If you close the browser tab, you can open web.whatsapp.com again later and your messages will still be there.

What to do if the QR code will not scan

Make sure your phone's camera is clean and has enough light to see the QR code clearly. Hold your phone about six inches away from the screen and keep it still for a few seconds — the camera needs time to focus. If the code still will not scan, try closing and reopening WhatsApp on your phone, then go back to Linked Devices and try again.

If you are using WhatsApp Web, try refreshing the page in your browser (press Ctrl+R on Windows or Command+R on Mac). If the QR code still does not work, sign out of WhatsApp on your phone completely, then sign back in. This resets your linked devices and usually fixes scanning problems. You can also try a different browser — sometimes one browser works better than another on your computer.

Keeping your phone connected while using WhatsApp on your computer

WhatsApp on your computer only works when your phone is turned on and connected to the internet — it does not matter if it is WiFi or mobile data. Your phone does not need to be near your computer; it just needs an active internet connection. If your phone loses internet or you turn it off, your computer will show a "Phone offline" message and you will not be able to send or receive messages until your phone reconnects.

This is different from some other messaging apps that store messages on their servers. WhatsApp keeps your messages on your phone, so your computer is just displaying what is on your phone. If you want to use WhatsApp on your computer while your phone is off, that is not possible with WhatsApp — you would need to switch to a different messaging service.

Signing out and unlinking your computer

To stop using WhatsApp on your computer, open WhatsApp on your phone, go to Settings (iPhone) or tap the three dots menu (Android), and tap "Linked Devices". You will see your computer listed with the name of the device and when it was last used. Tap it and select "Unlink" or "Sign Out". Your computer will when ready disconnect and you will need to scan the QR code again if you want to reconnect.

If you are uninstalling the WhatsApp app from your computer, you do not need to unlink it first — just delete the app normally. On Windows, right-click the app in your Start menu and select "Uninstall". On Mac, drag the WhatsApp icon from your Applications folder to the Trash. On a browser, you can straightforward close the tab or bookmark it for later use without any sign-out steps.
