WhatsApp on Computer: How to Run WhatsApp From Your PC (and When a Shared Inbox Wins)

WhatsApp on computer is easy to set up: open web.whatsapp.com or install the WhatsApp Desktop app, scan a QR code with your phone, and your chats appear on your PC. The catch is what most people miss — WhatsApp Web and WhatsApp Desktop are mirrors of one phone, not a shared workspace, so the account stays tied to a single device and a single person at a time. If several people need to answer customers from a computer, a shared browser inbox changes the equation.

In 30 seconds

• WhatsApp on computer works in two ways: the browser version at web.whatsapp.com and the separate WhatsApp Desktop application.
• Both connect by QR code. On Android: three dots → Linked devices → Link a device. On iPhone: Settings → Linked devices → Link a device.
• Your phone can be switched off and the computer session keeps working — but the phone must connect to the internet at least once every 14 days, or WhatsApp signs the linked devices out. One account can carry up to four linked devices.
• One WhatsApp account = one main device. A desktop session is a mirror of that phone, not an independent login.
• For a team, a shared browser inbox (like Bzzip) is the practical route: everyone works in one inbox in the browser, on one business number.

WhatsApp Web vs WhatsApp Desktop vs a shared browser inbox

How to use WhatsApp on your computer (step by step)

1. Decide between the browser and the desktop app. Go to web.whatsapp.com and you are in the browser version — nothing to install. If you prefer a separate window and native notifications, download the desktop app for Windows, macOS or Linux. The desktop app is basically the same web client wrapped in a standalone program.

2. Scan the QR code with your phone. Open WhatsApp on the phone and follow the menu path:
- Android: three dots in the top-right corner → Linked devices → Link a device.
- iPhone: Settings → Linked devices → Link a device.

Then point the phone camera at the code on the screen and confirm.

3. Wait for the sync. Your chats, contacts and media load into the desktop client. It is a mirror, so anything you send from the PC also appears on the phone.

4. Use it the way you use the phone — but on a bigger keyboard. Text, voice notes, images, documents and calls all work. The practical difference is typing speed and handling volume: you can keep a large conversation list open while replying.

5. Know when to unlink. If you ever need to remove the computer, go back to Linked devices on the phone and log the session out from there. Sessions stay active until you remove them, or until the primary phone goes 14 days without an internet connection.

Before you invest more time in the desktop route, it is worth reading multi-device vs multi-user: what you actually need — because most people asking for "WhatsApp on computer" are actually asking for a second pair of hands.

The part most guides skip: one account, one person

Here is the honest limitation. WhatsApp Web and WhatsApp Desktop do not create an extra login. Your WhatsApp account has one primary device, and every linked computer session is a mirror of that phone. That has three consequences worth understanding before you move your customer conversations onto a PC:

• If the phone stays offline for more than 14 days, WhatsApp unlinks the desktop sessions and you have to scan the QR code again. This is the rule that catches people who travel and leave the phone in a drawer.
• Your colleagues cannot share that account as a working inbox. Two people cannot sit in the same WhatsApp account and split chats between them. Whoever is linked is operating your personal account — with your contacts, your groups and your history visible.
• Everyone linked to that account can see the conversations. Data and chats are visible to everyone with that same account open. For a small business this is a real risk, not a technicality.

So if the goal is "answer customers from my computer while I am at the desk", WhatsApp Web is the correct and free answer. If the goal is "my team answers customers from computers while I am travelling", you need a shared inbox — that is a different product category, and it is worth reading what a shared WhatsApp inbox really is before you pay for one.

When a shared browser inbox makes more sense

Bzzip is a shared WhatsApp inbox with an AI agent for small businesses — free to start, AI free on your own key; more channels on the way. It runs in the browser, and that is the point: unlike WhatsApp Web, where the session is bound to one phone and one user, in Bzzip the whole team works in one inbox on one business number.

What that looks like in practice:

• The whole team in one inbox. No seat limit on any plan. The phone is no longer a single point of failure for your customer replies.
• WhatsApp works today. You connect by QR code, the same way you link a computer, or through an API connection. Instagram Direct works on paid plans and is enabled on request (through a third-party service, not an official Meta connection, so Instagram may ask you to verify the account). Facebook Messenger and TikTok are not yet available.
• An AI agent that answers from your own knowledge base. On paid plans the AI is included without any key. Bring your own Anthropic or OpenAI key and the agent is free — Bzzip does not charge on top, there is no message limit, and the key is stored encrypted. Your provider bills the tokens, which for a small team is usually cents per day. More on the mechanics in using the WhatsApp AI agent with your own API key and how the AI agent works.
• Honest limits. The agent replies only from the knowledge base. When it is not confident, it hands the conversation to a human. It does not run broadcasts or follow-ups, and it does not book appointments in your calendar.

What WhatsApp messaging costs

WhatsApp itself is free on web and desktop. If you run a business number through the API, Meta charges per delivered message — there is no longer a "per conversation" fee. Since 1 October 2026, service messages (replies to a customer inside the 24-hour window) are paid, with the first 1,000 messages per month free per business number — free messages do not accumulate month to month. Utility template pricing is set per recipient country: Brazil $0.0068, Mexico $0.0085, Colombia $0.0008, Peru $0.0300, Argentina $0.0260, Spain $0.0200. The free window after a click-to-WhatsApp ad or CTA is 72 hours. Always check Meta's rate card before you quote a number to a customer.

Limitations worth stating plainly

• WhatsApp Web and Desktop are mirrors of one account. One phone, one user, no team features, no AI, no multi-user inbox. The phone only has to reconnect every 14 days.
• Linking a computer exposes that account's chats to anyone else linked to it.
• Desktop sessions need to be revoked manually if a machine is lost or replaced.
• Meta charges for business messaging from 1 October 2026; free monthly allowances do not roll over.
• A shared inbox means a new business number and a different onboarding flow. It is more setup than scanning a QR code — worth it only when more than one person really answers customers.

FAQ

Can you use WhatsApp on a computer?
Yes. Open web.whatsapp.com in any browser and scan the QR code on the page with your phone, or install the WhatsApp Desktop app for Windows, macOS or Linux and scan its QR code. Your chats then appear on your PC and sync with the phone. The caveat: this mirrors your phone rather than creating an independent account, so the phone has to reconnect to the internet at least once every 14 days or WhatsApp signs the desktop session out.

Can you use WhatsApp on a computer without your phone?
Yes, and this surprises most people: linked devices work even when the phone is switched off, out of battery or in another country. The real requirement is different — your phone must connect to the internet at least once every 14 days, otherwise WhatsApp unlinks the desktop sessions and you scan the QR code again. You cannot link a device that has never been linked before, and you can link up to four devices to one account.

WhatsApp Web or WhatsApp Desktop — which should I use?
Both connect with the same QR code and show the same conversations; the Desktop app is essentially the web client in its own window, with native notifications and a taskbar icon, while Web needs no install and is better on a shared or temporary computer. Pick Web if you want to start in seconds, pick Desktop if you leave the window open all day. If you need several people to work the same number, neither is the answer — that requires a shared inbox, and our guide on what a shared WhatsApp inbox really is covers the difference.

Can I install WhatsApp on my PC?
Yes, the desktop app is a separate download for Windows, macOS and Linux, and it is free. Once installed you scan a QR code with your phone to link it, and the app behaves like the browser version. You can also skip the install and use the browser at web.whatsapp.com, which is handy on a shared or temporary machine because nothing is stored locally on that computer.

Is it safe to use WhatsApp on my laptop?
It is broadly safe — the connection to your phone is encrypted — but there are practical risks. Because the session is tied to your personal account, anyone with access to that laptop and an active linked session can read your chats and contacts. On a shared computer, log the device out from your phone when you are done.

Can I use WhatsApp on my PC using my phone number?
Yes — that is exactly how it works. The desktop client has no separate number; it uses the number already registered on your phone, and the QR scan confirms the pairing. Messages on the PC arrive on the same number, with the same contacts and history. If you want a number owned by the business, that is a different setup: a business number in a shared inbox.

Can two people use WhatsApp Web at the same time?
No. A WhatsApp number has one primary device and one session per linked device: the computer you open shows the same conversation the phone shows. There is no chat assignment, no queue and no per-person history. For that you need a shared inbox, where each person signs in with their own account and works the same number — the difference is laid out in what a shared WhatsApp inbox really is.
