How to Make Calls on WhatsApp Web: Complete Tutorial

WhatsApp Web Calling Requirements

Before you can place a WhatsApp call from your browser or desktop app, check these requirements so calls work reliably.

• Supported account and contact: You and the person you want to call must both have active WhatsApp accounts. You can only call contacts who use WhatsApp; you cannot call a regular phone number that isn’t on WhatsApp from the web. If you need to call landlines or mobile numbers directly over the internet, consider a VoIP service such as Telvio (more on that at the end).
• Linked device: Sign in to WhatsApp Web (web.whatsapp.com) or the WhatsApp Desktop app by linking your phone with the QR code. If you use WhatsApp’s multi-device feature and have linked devices, the web or desktop client can place calls even when your phone is offline. If you haven’t enabled multi-device, your phone must stay connected to the internet while you use WhatsApp Web.
• Browser or desktop app: Use a modern browser (Chrome, Edge, Firefox, or Safari) or the official WhatsApp Desktop app for Windows or macOS. Keep your browser and WhatsApp Desktop updated to the latest version.
• Hardware and permissions: Your computer needs a working microphone to make audio calls and a camera if you want video. Grant the browser or app permission to access microphone and camera when prompted.
• Network: A stable internet connection is essential. For decent audio-only calls expect at least 100–200 kbps upload/download; for good-quality video plan on 1–2 Mbps or higher. Wired Ethernet or a strong 5 GHz Wi‑Fi connection reduces latency and dropouts.
• System settings: Ensure your operating system’s microphone and camera are not muted or blocked. If you use external headphones or a USB microphone, set them as the default input/output devices in OS sound settings.

If your use case requires calling regular phone numbers (landlines or mobiles) rather than WhatsApp contacts, see guides on VoIP and virtual numbers: VoIP phone services explained, virtual phone numbers guide, and how to make international calls.

Step-by-Step Guide to Making Calls

This section covers both voice and video calls from WhatsApp Web or the Desktop app.

1. Open WhatsApp Web or the Desktop app

• Go to web.whatsapp.com in a supported browser, or open the WhatsApp Desktop app.
• Scan the displayed QR code with WhatsApp on your phone (Open WhatsApp on mobile > Settings or Menu > Linked Devices > Link a Device). If you already linked the desktop device previously, you’ll be signed in automatically.

2. Find the contact you want to call

• Click the chat for the person you want to call. If you don’t have an existing chat, use the search box to find the contact and open a conversation.

3. Grant microphone and camera access

• The first time you try to call, the browser or app will ask for permission to use the microphone and camera. Click Allow. If you deny permissions, the call won’t work.

4. Start the call

• In the chat window, click the phone icon to place a voice call or the video icon for a video call. On the Desktop app you’ll see these icons in the top right of the chat header.
• Wait for the contact to answer. The incoming call appears on their WhatsApp client (mobile or desktop).

5. During the call

• Control microphone and camera with the toggle buttons in the call window.
• Switch between audio-only and video by turning your camera on or off during the call.
• Mute/unmute your microphone or change output device (speakers/headphones) from your operating system’s sound settings or the app’s call controls.
• To end the call, click the red hang-up button.

6. Receiving calls on web

• If you’re signed into WhatsApp Web and the browser is open, incoming calls will ring in the browser window. If you minimized or closed the tab, you might not see the incoming call depending on your browser’s notification settings.

Quick tips for first-time users

• If you don’t see call icons, update your browser or the Desktop app, then reload.
• If the other person doesn’t get the call, confirm they updated WhatsApp and granted microphone/camera permission.

If you’re looking for alternatives to call non-WhatsApp numbers (for example, family members without WhatsApp), a VoIP app like Telvio lets you call regular phone numbers over Wi‑Fi or mobile data. Telvio offers per-second billing, low rates to many countries, and doesn’t require registration or account setup.

Troubleshooting Common Call Issues

If you can’t make or receive a call on WhatsApp Web, follow this checklist to identify and fix common problems.

No call buttons or greyed-out icons

• Update and reload: Refresh web.whatsapp.com or restart the Desktop app. Verify you run the latest version of your browser or the app.
• Relink device: Open WhatsApp on your phone and re-link the desktop session via Settings > Linked Devices.
• Multi-device: If you rely on multi-device, confirm your phone and linked devices are updated.

Browser permissions blocked

• Check site permissions: In Chrome/Edge/Firefox/Safari, open the site settings for web.whatsapp.com and confirm microphone and camera are allowed.
• OS permissions: On Windows, go to Settings > Privacy & security > Microphone/Camera and allow apps to access the devices. On macOS, go to System Settings > Privacy & Security.

Microphone or camera not detected

• Test hardware: Use another app (Voice Recorder, Camera) to confirm the devices work.
• Select the right device: Some systems default to built-in audio. In the call window or OS sound settings, set the correct input/output device.
• Close other apps: Close apps that may lock the camera or mic (Zoom, Skype, Teams).

Poor audio or video quality

• Check your bandwidth: Run a speed test. Move to a stronger Wi‑Fi network, switch to wired Ethernet, or reduce other network activity.
• Change to audio-only: If video lags, turn off your camera to save bandwidth.
• Restart router: A quick router reboot can clear transient issues.

Calls drop or fail to connect

• Firewall or VPN: Some enterprise firewalls block VoIP traffic. Temporarily disable VPNs or test on a different network.
• Browser extensions: Disable extensions that affect media or security (ad blockers, privacy extensions) and try again.

Incoming calls don’t ring

• Notifications blocked: Ensure your browser and system allow notifications from WhatsApp Web.
• Tab focus: Some browsers limit background activity. Keep the WhatsApp tab open or use the Desktop app for more reliable notifications.

If you need to call a phone number directly and WhatsApp won’t support it, consider a VoIP option that places calls to mobile and landline numbers. For a simple alternative, see free online video calling platforms and VoIP guides like how to make international calls.

Differences Between Mobile and Web Calling

Understanding what WhatsApp Web can and cannot do helps you pick the right setup for your needs.

What the mobile app does that web may not:

• Full background support: Mobile WhatsApp handles calls across locked screens, manages cellular and Wi‑Fi handoffs, and integrates with native dialer notifications. Desktop or web clients may not receive calls if the browser is closed or notifications are blocked.
• Some legacy features: Mobile apps sometimes get new calling features first (for example, certain group call behaviors or in-call effects).
• Simpler sharing: Mobile lets you quickly switch to sharing contacts or phone numbers from your device.

What web/desktop offers that mobile might not:

• Larger screen and full keyboard: Desktop suits longer video meetings and screen sharing workflows (where supported).
• Stable external devices: Desktop systems often use professional USB microphones or webcams and wired Ethernet for consistent quality.
• Multi-tasking: You can keep multiple chat windows and files open on your larger display.

About multi-device independence

• If your WhatsApp account uses multi-device (linked devices feature), the Desktop app and web can place and receive calls even if your mobile phone is offline. Otherwise your phone must remain connected to handle calls and sync messages.

Calling phone numbers vs calling on WhatsApp Web

• WhatsApp Web calls only other WhatsApp users. If you need to call real phone numbers (landlines or mobiles) directly from your computer, use a VoIP service or virtual phone number solution. See the differences between VoIP and app-based calling in the VoIP phone services explained and consider virtual numbers from our virtual phone numbers guide.

Practical example

• Use mobile WhatsApp for quick calls when you’re away from your desk. Use WhatsApp Web or Desktop for longer calls, meetings, or when you prefer a headset and stable connection.

Tips for Best Call Quality

These practical tips help you get clear audio and smooth video on WhatsApp Web calls.

Network and connection

• Prefer wired Ethernet when possible. If you use Wi‑Fi, connect to the 5 GHz band for lower interference and higher throughput.
• Close or pause large downloads and streaming services during calls to free bandwidth.
• If your ISP supports Quality of Service (QoS) on your router, prioritize video conferencing or VoIP traffic.

Hardware and system settings

• Use a dedicated headset or USB microphone. Built-in laptop mics pick up room noise and produce echo.
• Test audio devices before the call: on Windows use Sound settings; on macOS use Sound in System Settings.
• Keep camera clean and positioned at eye level. Good lighting makes a big visual difference—face a window or use a desk lamp.

WhatsApp-specific settings and behavior

• Mute your mic when not speaking to reduce background noise.
• Turn off video if you notice significant lag; audio-only calls require substantially less bandwidth.
• If your microphone volume is low, increase input gain in your OS settings rather than relying on software volume boosts that add noise.

Software and browser tips

• Use the Desktop app for more stable background behavior and native notifications.
• Keep one browser tab for the call and avoid dozens of media-heavy tabs during calls.
• Disable browser extensions that interfere with media permissions or manipulate web content.

Advanced steps for consistent quality

• If calls often degrade, try a different DNS provider (e.g., Google DNS or Cloudflare) to improve name resolution speed.
• For frequent international calls, consider a dedicated VoIP app or virtual number service. If you need to place calls to non-WhatsApp numbers from your computer, a low-cost VoIP app can offer reliable quality and predictable rates—see guides to free virtual phone numbers and how to make international calls.

Practical examples

• Example A: Remote worker on a laptop — plug in wired Ethernet, use a USB headset, close streaming apps, and use the Desktop app for stable calls.
• Example B: Quick family calls — use mobile WhatsApp when you’re on the move; switch to WhatsApp Web for longer video chats when at your desk.
