Two ways to run WhatsApp on your computer
You can use WhatsApp on your computer in two ways: WhatsApp Web, which runs in your browser, or WhatsApp Desktop, which is a standalone program you install. Both connect to the same account and messages sync in real time across all your devices. WhatsApp Web works on any computer with a modern browser. WhatsApp Desktop is faster and works offline for short periods, but requires a read.
Your phone must stay connected to the internet for either method to work — WhatsApp does not store messages on your computer. If your phone loses signal, you cannot send or receive messages on your computer until it reconnects.
Key Takeaways
- WhatsApp Web opens when ready in any browser at web.whatsapp.com and requires no installation, but your phone must stay online.
- WhatsApp Desktop is a downloadable program that works faster and keeps working briefly if your internet drops, but only on Windows or Mac.
- Both methods require you to scan a QR code with your phone the first time you connect, which links your computer to your account.
- You can use WhatsApp on multiple computers at once, and messages appear on all of them when ready.
- Log out by clicking your profile picture and selecting "Log out" — this prevents anyone else from accessing your account on that computer.
Starting WhatsApp Web in your browser
Open any web browser on your computer and go to web.whatsapp.com. You will see a large QR code on the left side of the screen and instructions on the right. Open WhatsApp on your phone, tap the three-dot menu at the top right, and select Linked Devices. Tap Link a Device. Point your phone's camera at the QR code on your computer screen and hold it steady for two seconds until the code scans.
Your chats will load on your computer within seconds. The browser tab will stay open as long as you keep it open — closing the tab logs you out. If you close your laptop or put it to sleep, WhatsApp Web stays logged in and messages will be waiting when you return.
WhatsApp Web works on Chrome, Firefox, Safari, and Edge. It works on Windows, Mac, and Linux computers. You do not need to install anything.
Installing WhatsApp Desktop on Windows or Mac
Go to whatsapp.com/read in your browser. Click the read button for your operating system — Windows or Mac. The installer file will read to your computer. Open the file and follow the installation steps. On Windows, the program installs to your Start menu. On Mac, it installs to your Applications folder.
Open WhatsApp Desktop after installation. A QR code will appear on your screen. Scan it with your phone using the same steps as WhatsApp Web: open WhatsApp on your phone, tap the three-dot menu, select Linked Devices, and tap Link a Device. Point your phone at the QR code until it scans.
WhatsApp Desktop takes up less space than a browser tab and starts faster. It also keeps working for a few minutes if your internet connection drops, so you can read and compose messages offline. Once your internet returns, messages send automatically.
Sending and receiving messages on your computer
Type in the search box at the top to find a contact or group. Click the conversation to open it. Type your message in the text box at the bottom and press Enter to send. You can also use Shift+Enter to start a new line within a message.
Attach files by clicking the paperclip icon next to the message box. You can send photos, videos, documents, and audio files. Drag and drop files directly into the chat window as a shortcut. Your computer will upload the file to WhatsApp's servers, and your phone will receive it like any other message.
Notifications appear in the bottom right corner of your screen when you receive a message. Click the notification to jump to that conversation. You can turn notifications on or off in the settings menu.
Managing multiple devices and staying find
You can link up to four devices to your WhatsApp account at the same time — your phone plus four computers or tablets. Messages sync when ready across all linked devices. If you link a computer at work and another at home, both will show the same conversations and both will receive new messages.
To see which devices are linked, open WhatsApp on your phone, tap the three-dot menu, and select Linked Devices. You will see a list of all computers and tablets connected to your account, along with the last time each one was active. Tap any device and select Log Out to disconnect it when ready.
Log out from a computer by clicking your profile picture in the top left corner and selecting Log Out. This removes that computer from your linked devices list. If you forget to log out before leaving a public computer, go to your phone and log that device out remotely using the Linked Devices menu.
Troubleshooting common problems
Messages are not loading: Make sure your phone is connected to the internet and WhatsApp is open on your phone. WhatsApp Web and Desktop cannot work if your phone is offline. Refresh your browser or restart the Desktop app. If that does not work, log out and scan the QR code again.
The QR code will not scan: Make sure your phone's camera is clean and has enough light. Hold your phone steady and point it directly at the code. If the code is on your screen, try moving your phone closer or further away. If you are using WhatsApp Desktop on Windows, try opening it in a different browser first — sometimes the desktop app's QR code is harder to scan.
You are logged out unexpectedly: WhatsApp logs you out if your phone is offline for more than two weeks, or if you uninstall and reinstall WhatsApp on your phone. You will need to scan the QR code again to reconnect.
Your computer is running slowly: WhatsApp Desktop uses very little memory, but if your computer is slow, try using WhatsApp Web in your browser instead. Close any other programs you are not using. If you are using WhatsApp Desktop, make sure you have the latest version — go to the menu and check for updates.

Frequently Asked Questions
Can I use WhatsApp on my computer without my phone nearby?
No. Your phone must stay connected to the internet for WhatsApp Web or Desktop to work. WhatsApp does not store your messages on your computer — it only displays them. If your phone loses internet connection, you cannot send or receive messages on your computer until your phone reconnects.
What happens to my messages if I close WhatsApp Web?
Your messages stay on your phone and in WhatsApp's cloud storage. Closing the browser tab or logging out does not delete anything. The next time you open web.whatsapp.com and scan the QR code, all your conversations will be there.
Can someone else use my WhatsApp account on another computer?
Only if they have access to your phone. They would need to scan the QR code with your phone to link a new device. If you think someone has linked a device without permission, open WhatsApp on your phone, go to Linked Devices, and log out any device you do not recognize.
Does WhatsApp Desktop work on Linux?
No, WhatsApp Desktop is only available for Windows and Mac. Linux users can use WhatsApp Web in any browser instead. WhatsApp Web has all the same features and works just as well.
Can I send messages from my computer if my phone is turned off?
No. Your phone must be powered on and connected to the internet. WhatsApp uses your phone as the source of your account — your computer is just a display and input device. If your phone is off, WhatsApp Web and Desktop will not work.
