Download Viber — QR-Activated Desktop Messenger with Encrypted Calls for Windows PC v29.3.0.0 for Windows PC

Desktop companion to Viber on your phone: scan a QR code to activate, then message, share files and make end-to-end encrypted voice and video calls...

Features

• Activation by QR code takes under a minute, after which chats, contacts and calls sync between your phone and PC without manual exporting, backup files or complicated pairing procedures to learn.
• One-to-one and group voice and video calls run directly from the desktop, so long family or community calls do not drain your phone battery or tie up the handset for hours.
• Chats and calls are end-to-end encrypted by default, with disappearing messages available when you want a conversation to clear itself automatically afterwards without deleting anything by hand each time.
• Communities, stickers, GIFs and file sharing all work fully on desktop, making group organisation, celebrations and everyday conversation feel complete rather than like a cut-down companion view of the phone.
• The app is completely free for Viber-to-Viber messaging and calling, with no subscription tier locking basic chat, group or call features behind a paywall for ordinary personal use at home.

Considerations

• The desktop app cannot create an account, so a phone with Viber activated and signed in is mandatory before the PC version becomes usable at all for anyone starting out.
• Some mobile-first features reach the desktop client noticeably late, so the newest stickers, community tools or settings occasionally appear on phones weeks before desktop users see them at all.
• Your contacts must also be on Viber to be reachable, because there is no way to message people who only use other messengers, email or plain SMS from this app.

Understand Viber for Windows as a linked device, not a second account, and everything about it makes sense. The phone holds the identity, the phone number and the activation; the PC borrows that identity through the QR scan and then works as a full messaging station. Chats update on both devices, so a conversation can start while you are out and finish at your desk without forwarding anything to yourself. Calls benefit most from the move: a headset and a stable PC connection make group voice and video calls easier to hear and easier to manage, especially in communities where several people speak in turn. Stickers, GIFs and disappearing messages keep the lighter side of Viber intact, and end-to-end encryption applies by default rather than hiding behind a special secret-chat mode you must remember to start. Files shared from the computer go straight into the conversation, which is handy for photos and documents already stored on the PC. What the desktop does not do is stand alone. Close the phone account or lose the phone, and the desktop loses the thing it is linked to. That dependency is the design, not a bug, and it shapes every strength and limitation on this page.

Viber suits households, friend groups and communities that already talk on Viber by phone and simply want those same conversations on a computer. If your family group, workplace community or overseas relatives are already here, the desktop app is an obvious, free upgrade to your day: faster typing, better calls and easier file sharing, with nothing new for your contacts to install or learn. It also suits people who make long international Viber-to-Viber calls and would rather use a headset at a desk than hold a phone. Start elsewhere if you are choosing a messenger from zero. Viber cannot message people who are not on Viber, so a contact list living mainly on WhatsApp, Telegram or iMessage will not be reached from here, and no desktop feature compensates for an empty network. Also start elsewhere if you need a desktop account without a phone: activation without the phone app is impossible, by design. Privacy-focused users who want registration without a phone identity, or teams needing business integrations and admin controls, will likewise find better fits. The honest test takes ten seconds: open Viber on your phone and look at how many of your real conversations already live there.

Imagine the weekly family call, with relatives in two time zones and a group chat that has been trading photos all day. You open Viber on the PC instead of the phone, scan nothing because the link is already active, and the day's conversation is simply there, including the photos, ready to view on the big screen. Starting the group video call from the desktop puts faces in a window you can arrange beside your notes, and a headset keeps your hands free. When someone asks for a document stored on the computer, you attach it directly into the chat rather than emailing it to your phone first. A message you do not want lingering can be sent with a disappearing timer. Afterwards the call history and any missed messages sync back to the phone, so leaving the desk does not break the thread. Nothing in that session is dramatic, and that is the point: Viber desktop removes small frictions, the phone battery, the tiny keyboard, the file shuffle, the squinting at photos, one by one. It does not add a new network or replace the phone. For an existing Viber family, that quiet convenience is exactly enough.

Download ViberSetup.exe, the small official setup bootstrapper for Viber 29.3.0.0, and keep an internet connection active because it downloads the actual app during installation.

Double-click ViberSetup.exe and let it download and install Viber on Windows 10 or 11. Do not disconnect during setup, as the small file is only the starter, not the full app.

Launch Viber, open Viber on your phone, and scan the QR code shown on the PC screen. You need an existing phone account, because desktop cannot create one.

Is Viber really free to use?

Yes, Viber-to-Viber messaging and voice and video calls are free on both phone and desktop, including group calls and communities. The desktop app itself costs nothing to download or activate. Charges only appear if you choose optional paid services such as Viber Out calls to ordinary phone numbers, which are separate from normal app-to-app calls.

Can I use Viber on my computer as well?

Yes, that is exactly what this Windows version is for. Install ViberSetup.exe, open the app, then scan the QR code it shows using Viber on your phone. Your chats and calls then sync to the PC, so you can type on a full keyboard, share files from the computer and take calls at your desk.

Can I use Viber without a phone number?

No. A Viber account is created on a phone with a phone number, and the desktop app can only be activated by scanning its QR code with that phone app. There is no desktop-only sign-up and no way to register a new account from Windows, so you need the phone at least for activation and account recovery.

Can I use Viber on multiple devices?

Yes, within Viber's companion model. Your phone stays the primary device, and you can activate the desktop app on your Windows PC as a linked secondary device by QR code. Messages and calls sync across both, so a conversation started on the phone can continue on the PC without exporting or forwarding anything manually.

How do I know if my contacts are on Viber?

Viber checks your phone address book and marks contacts who already have Viber, so they appear ready to message inside the app on phone and desktop. Contacts without Viber will not show as reachable for free app-to-app calls. You can invite them from the app, but until they join you cannot message them through Viber.
