Laptop webcams weren't made for calls.
You look smaller, darker and further away on camera than you do in person — and none of it is your fault.
CamTuner fixes all four before the call app sees a single frame. See it live
Wrong shape
4:3 feeds leave awkward bars or clumsy crops on every call app.
Off-center
You drift to the edge of the frame while half the shot is empty room.
Too far away
Wide-angle lenses turn you into a tiny figure in your own meeting.
Messy background
Laundry, cables, roommates — whatever's behind you is in the shot too.
Tune it live. Right here.
Start your camera and scroll. Every control below is the real thing, the same ones you get inside the extension.

Move in without moving the camera
Dial in a fixed zoom, or switch to auto and let CamTuner keep you at the right size as you lean in and out.

Put yourself exactly where you want
Anchor your shot to any of nine positions, or switch to Auto and let Center Stage track your face to keep you framed as you move. Tracking runs locally, so no video is ever uploaded.
Tidy up what's behind you
Blur a messy room or swap it for an image. Person segmentation happens on your device, frame by frame.
Correct the orientation
Mirror your feed or flip it vertically for webcams and rigs that come out the wrong way around.
Flip horizontally
Turn upside down
Small extension. Big difference.
Everything you need to fix a bad camera angle, nothing you don't.
Zero-latency framing
CamTuner hooks the browser's camera stream directly, so adjustments are applied in real time with no visible delay.
<2ms added latency
Private by design
Frames are processed locally with WebCodecs. No video, audio or settings ever leave your machine.
Works everywhere
If a website can ask for your camera, CamTuner can tune it. No per-app setup.
Your look, remembered
Settings persist between sessions, and you can set different framing per site.

Questions, answered
Is CamTuner really free?
Yes. It's a free extension with no account, no trial and no watermark.
Does my video get uploaded anywhere?
No. Everything is processed on your device inside the browser. Your camera feed is never sent to us or to any server.
Which video call apps does it work with?
Any website that uses your webcam through the browser, including Google Meet, Zoom in the browser, Microsoft Teams, Discord and more.
Will it slow down my computer?
Cropping and zooming are very light. Face tracking and background effects use more CPU, so you can switch them on only when you need them.
Do I need to change settings in Zoom or Meet?
No. Keep using your normal camera. CamTuner adjusts the stream before the site ever sees it.
