Evaer for WhatsApp: A Third-Party Recorder for WhatsApp Voice and Video Calls

WhatsApp has no record button. There is no built-in way to save a voice call or a video call on any platform — not on Android, not on iOS, and not in the WhatsApp desktop application. Calls simply happen and then they are gone. For a one-minute call with a friend that is fine. For a supplier confirming a price, a client changing a delivery date, or a family member giving instructions you will need later, it is a real problem.

Evaer for WhatsApp solves it from the outside. It is a third-party call recorder for Windows that sits alongside the WhatsApp desktop app and records voice and video calls to your own computer, in full quality, without WhatsApp being modified in any way and without the other party being notified.

Third-party recording, on your side of the call

Because WhatsApp offers nothing native, every option has to come from outside the app. The usual workaround is a screen recorder, which captures your whole desktop — notification pop-ups, other windows, a mouse cursor drifting across the frame, and a picture that goes soft the moment you resize the call window.

Evaer takes a different route. It attaches to the WhatsApp desktop client and captures the original audio and video streams of the call directly, at up to 1080p. WhatsApp itself is untouched: same app, same version, same account, no patched build and no risk of a ban for using a modified client.

What that means in practice:

  • The recording is a clean picture of the call — no window chrome, no buttons, no chat sidebar, no cursor.
  • Quality does not degrade when you move or resize the WhatsApp window while recording.
  • Audio and video are captured from the same source, so they stay in sync and no system sounds leak into the file.
  • Nothing is uploaded anywhere. Files are written to your local disk as the call happens.

The other person is never told

WhatsApp does not display any recording indicator, and Evaer does not add one. There is no banner, no chat message, no change to the call interface and nothing in the call quality that hints at what is happening. On the other end it is an ordinary WhatsApp call.

That silence is the whole point for most users. People behave differently when they know a device is recording — they hedge, they repeat themselves, they ask for the question in writing. Evaer lets you keep an accurate record of what was actually said, whether that is a job interview, a verbal agreement, a medical call with an elderly parent, or a conversation you may need to refer back to in a dispute.

Recording laws vary widely between countries and between states, and some require all parties to consent. Silent recording is a technical capability, not legal advice — make sure you are allowed to record the call before you do.

What you can record

  • One-to-one WhatsApp voice calls
  • One-to-one WhatsApp video calls
  • Group voice and video calls
  • Long calls, with no time limit in the licensed version

Layouts, formats and audio

Video calls can be saved as side-by-side landscape, side-by-side portrait, picture-in-picture, or as separate video files — one per participant — which is handy when you only need the other person’s face for a clip. In the combined layouts you can swap who appears in the main window while the recording continues, and drop a video channel in or out mid-call.

Files are written as MP4 (H.264) or AVI, with an optional separate MP3 audio track. Resolution, frame rate, aspect ratio and codec are all configurable, or Evaer can adapt to whatever WhatsApp is sending. Voice-only calls are saved as MP3 automatically.

For audio you can choose both sides mixed, your microphone only, or the remote party only — the last one gives you a clean copy of the other person’s voice for transcription or for a record where only their side matters. Built-in echo cancellation keeps speaker output from bleeding back into the recording when you are not on a headset.

Evaer can also start recording automatically whenever a WhatsApp call connects, so you never lose the first thirty seconds of a call because you were still looking for the button.

Trial and system requirements

Evaer for WhatsApp runs on Windows 10 and 11 (32-bit and 64-bit) and works with the WhatsApp desktop application. The trial is fully functional for 14 days, after which a license is required. Setup takes about two minutes: install, run WhatsApp, press record when the call connects.

No. WhatsApp has no recording indicator and Evaer does not add one, so at the other end the call looks completely normal.

MP4 (H.264) or AVI at up to 1080p, with an optional separate MP3 track. Voice-only calls are saved as MP3.
