WhatsApp Web lets you send and receive WhatsApp messages on your PC by linking your phone at web.whatsapp.com with a QR code — no installation required and your chats stay synced with your phone.
It runs entirely in Chrome, Edge, Firefox, Opera, or Safari on Windows 10 and Windows 11. Once linked, you can type with a full keyboard, drag-and-drop photos and documents, make voice and video calls from supported browsers, and stay logged in even when your phone screen is off, as long as your phone connects to the internet at least once every 14 days.
How to Log In to WhatsApp Web on PC
You link WhatsApp Web once, then your browser remembers the session. You do not need your phone and PC on the same Wi-Fi network anymore — both just need internet access.
Step-by-step: Link with QR code
1. On your PC, open web.whatsapp.com in Chrome or Edge. You will see a QR code and an option for Link with phone number instead.
2. On your phone, open WhatsApp and go to the Linked Devices menu:
- Android: WhatsApp > three-dot menu (top-right) > Linked devices > Link a device > unlock with fingerprint/PIN if prompted
- iPhone: WhatsApp > Settings (bottom-right) > Linked Devices > Link a Device > confirm with Face ID / Touch ID / passcode
3. Point your phone camera at the QR code on your PC screen. Hold it 15-30 cm away and make sure the PC brightness is at 70% or higher — low brightness is the most common reason the camera cannot read the code.
4. Wait 5-10 seconds for Chat syncing to finish. Your recent chats will appear in the left sidebar. Check Keep me signed in on the login screen if you use a private PC so you do not have to scan again after restarting the browser.
If you prefer not to scan, click Link with phone number instead on the PC, enter your phone number with country code, then on your phone go to Linked devices > Link a device and enter the 8-character code shown on the PC. The code expires in about 60 seconds, so enter it quickly.
How to log out securely
To log out from the PC: Click the three-dot menu above the chat list > Log out > Log Out to confirm. To log out remotely: On your phone go to WhatsApp > Linked devices, tap Windows / Chrome / Edge session, then tap Log Out. Always do this on shared, work, or library PCs.
How to Use WhatsApp Web for Messaging and Calls
The layout has three main areas: chat list on the left, conversation in the center, and profile/media details on the right when you click a contact name. All messages you send from the PC appear instantly on your phone and vice versa.
- Start a new chat: Click the New chat icon (speech bubble with +) at top-left > search name or phone number > click to open.
- Send files: Click the + / paperclip icon in the message box > Document, Photos & videos, or Camera. You can drag-and-drop up to 2 GB files directly into the chat window on Windows. For photos, use HD toggle in the preview to send at full resolution instead of compressed 1600px.
- Voice messages: Click the microphone icon > click lock icon to record hands-free > click Send. Press Esc to discard.
- Voice and video calls: Open a chat > click phone or camera icon at top-right. Calls work best in Chrome and Edge with microphone/camera permission set to Allow. Use a headset to avoid echo.
- Search and filter: Use the Search bar above chats with filters like Unread, Favorites, Groups, or type from: [name] to find messages from one person.
- Notifications: Click the bell icon above chats to mute all for 8 hours, 1 week, or Always. For per-chat mute: Right-click chat > Mute notifications > select duration. In Windows, allow notifications in Settings > System > Notifications > Chrome/Edge so message banners appear.
- Archive, pin, and star: Right-click a chat for Pin, Mute, Archive, Mark as unread, Block. Pin up to 3 chats to keep them at the top.
Keyboard shortcuts that save time on Windows
WhatsApp Web supports these shortcuts when the browser window is active:
- Ctrl + N: New chat

Press Ctrl + / in WhatsApp Web to open the full shortcut list.
WhatsApp Web vs. WhatsApp Desktop App: Which Should You Use?
Both sync to the same account and you can use up to 4 companion devices plus your phone. Use this guide to choose:
| Your situation | Best choice | Why |
|---|---|---|
| Quick access on any PC, no admin rights to install software | WhatsApp Web | Runs in browser, nothing to install, works on Windows 10/11 |
| Make frequent voice/video calls, share screen | WhatsApp for Windows from Microsoft Store | Native calling, background notifications, lower CPU use for calls |
| Slow PC with 4 GB RAM, many browser tabs open | WhatsApp for Windows | Uses ~180-300 MB RAM vs 400-700 MB for a heavy browser tab |
| Use multiple WhatsApp accounts or profiles | WhatsApp Web | Open each account in separate Chrome/Edge profile or Incognito window |
| Need offline access to file downloads | WhatsApp for Windows | Downloads save directly and stay available in Windows Downloads folder |
For most office PCs in 2026, start with WhatsApp Web. Install the Windows app only if you call daily or want calls to ring when the browser is closed.
Fix Login and Sync Issues on PC
Most WhatsApp Web problems fall into three causes: phone has no internet, browser session expired, or browser data blocks the connection. Check in this order because it resolves about 90% of cases without re-linking.
1. Confirm your phone can send a message. If the phone shows Connecting…, fix phone internet first.
2. Refresh the PC tab once with Ctrl + R. If it shows Phone not connected for more than 2-3 minutes, continue below.
3. Log out and link again only as a last step — unnecessary re-linking deletes undownloaded temporary files.
| Symptom | Likely cause | Fix with values |
|---|---|---|
| QR code will not scan or expires immediately | Low screen brightness, zoom above 100%, code older than 60 seconds | Set PC zoom to 100% (Ctrl + 0), brightness 70%+, click Refresh QR icon to generate new code, scan within 60 seconds at 15-30 cm distance |
| Stuck on Loading chats or Syncing 0% | Large chat history over 2-3 GB, unstable connection | Keep phone unlocked and WhatsApp open for 5-10 minutes, connect phone to Wi-Fi, limit to 10 Mbps+ connection. On phone: WhatsApp > Storage and Data > Manage Storage > clear files larger than 5 MB |
| Messages send on phone but do not appear on PC | Browser cache conflict or PC lost connection for 30+ minutes | Press Ctrl + R, then check PC internet. In Chrome: Settings > Privacy and security > Third-party cookies > Allow for web.whatsapp.com. Do not block all cookies |
| Phone not connected yellow banner | Phone offline, battery saver killed WhatsApp, VPN blocking | Turn off phone Battery Saver for WhatsApp: Android Settings > Apps > WhatsApp > Battery > Unrestricted. Disable VPN temporarily. Phone must come online at least once every 14 days or linked devices are logged out automatically |
| Cannot download photos, voice notes, PDFs | Browser blocked pop-ups/downloads, disk full | In browser address bar click Tune/Site settings icon > Downloads and Pop-ups > Allow. Free at least 1-2 GB on C: drive. Try Incognito window to rule out extensions |
| Calls have no mic/camera on PC | Permission denied in browser or Windows | Chrome: Settings > Privacy and security > Site Settings > Camera/Microphone > Allow for web.whatsapp.com. Windows: Settings > Privacy and security > Microphone/Camera > Let desktop apps access = On |
| Logged out every time browser closes | Clear cookies on exit enabled, Incognito mode | Use normal window, check Keep me signed in. Chrome: Settings > Privacy and security > Delete browsing data on exit > do NOT add web.whatsapp.com |
If nothing works: Clean re-link
1. On PC: Log out of WhatsApp Web.
2. In browser, clear site data for web.whatsapp.com only: Press Ctrl + Shift + Delete > Time range: Last 24 hours > check Cached images and Cookies > Clear, or in Chrome go to Settings > Privacy and security > Site Settings > View permissions > search whatsapp > Clear data.
3. On phone: Linked devices > tap old Windows/Browser session > Log Out.
4. Restart browser, open web.whatsapp.com again, and scan a fresh QR code. This fixes corrupted session tokens that a simple refresh cannot.
Privacy and Security Tips for PC Use
WhatsApp Web uses the same end-to-end encryption as your phone — messages are decrypted locally in the browser. The risk on PC is someone else accessing your logged-in session.
- Check linked devices weekly: Phone > Linked devices should show only your own PCs with correct last-active time. Remove anything unknown.
- Enable Screen lock for Web: On PC click Settings (gear) > Privacy > Screen lock > set 5-15 minute password. This locks the tab without logging out.
- Turn off message preview on Windows if you share a screen: Windows Settings > System > Notifications > turn off Show notification banners for the browser during presentations.
- Do not use QR-code generator or downloader extensions claiming to enhance WhatsApp Web — they can read your session. Use only web.whatsapp.com.
FAQ
Can I use WhatsApp Web without my phone being online?
Yes, for up to 14 days. WhatsApp now uses multi-device sync, so the PC works while the phone is off or has no internet, as long as you linked within the last 14 days. After 14 days offline, the phone must reconnect once or you will be logged out everywhere.
Why is WhatsApp Web not working in Firefox or Safari?
Messaging works in Firefox 100+ and Safari 15+, but voice/video calling is limited. If calls fail, switch to Chrome 110+ or Edge 110+ on Windows 10/11 and allow microphone/camera when prompted.
How do I send HD photos or large videos from PC?
After selecting a photo, click the HD icon in the preview toolbar before Send to keep original resolution up to 4096px. Videos are limited to 2 GB per file and documents keep original quality automatically.
