How to share your screen on WhatsApp

October 15, 2026 · By the Wachaut team

WhatsApp is the world's most used messaging app: when you want to show something to someone — a video, a TV moment, an error on their phone — the obvious move is to open WhatsApp and send it over. But sharing your screen live through WhatsApp has a catch: it lives inside the video call, drains battery, and quality suffers. Here are both ways to do it, ordered from simplest to most reliable.

Option 1: screen sharing inside a WhatsApp video call

WhatsApp includes screen sharing inside its video calls (mobile and desktop). It's quick when you're already on a call, but it pays to know its limits.

  1. Start a video call with the person or the group.
  2. Tap the Share screen button among the call controls.
  3. Confirm the notice and pick the app or screen you want to show.
  4. To stop, go back to the call and tap the button again or "Stop sharing".
Limits worth knowing:
  • Quality adapts to the call, not to your screen: text and fine detail look blurry.
  • On mobile, switching apps can cut the share, and battery drains fast.
  • With large groups the call degrades, and sharing your screen plus camera at the same time is not always possible.
  • When several people need to watch your screen at once, the video call is not the right stage.

Option 2 (recommended): share a Wachaut link over WhatsApp

Start a live broadcast of your screen on wachaut.com — no sign-up, nothing to install — and share the link + PIN it gives you over WhatsApp. Whoever opens it watches your screen in full quality, almost live. It's the best way to show something to a WhatsApp group: you don't fight the video call for bandwidth, and everyone gets in with one tap.

  1. Open wachaut.com/room and click "Share my screen".
  2. Pick the window or screen; tick the audio box if you want sound.
  3. Copy the invite (link with PIN included, one click).
  4. Paste it into the WhatsApp chat or group. Done: up to 20 viewers in real time.

Because it's a link, it doesn't matter where each person connects from — phone, tablet or computer, WhatsApp or any other chat. And when you finish, close the room and the links stop working: nothing is stored anywhere.

FAQ

Does the recipient need to install anything?

No. They just open the link in any browser, on phone or computer. No sign-up and no downloads for anyone.

How many people can watch my screen at once?

Up to 20 viewers in real time in the same room. That covers most WhatsApp groups.

Does the room link expire?

You can protect the room with a 6-digit PIN and close it whenever you want. When the broadcast ends the room disappears and the link stops working.

Does it work on a computer without installing apps?

Yes. Wachaut runs directly on Chrome, Firefox, Edge and Safari, on Windows, Mac and Linux.

Is the video quality actually good?

In a WhatsApp video call, screen sharing quality drops with the call. With Wachaut you stream in full quality (up to 1080p, 60 fps) with audio, and viewers receive it almost live.
