Frequently asked questions

Key distinctions behind the tool.

Is the camera feed uploaded?

No. Video is shown only in your browser and never sent to CalculatorX servers.

Why is the image mirrored?

Mirror (flip) is on by default so it behaves like a bathroom mirror. Uncheck to see the raw camera view.

Can I use the back camera on a phone?

Try Switch camera. Support depends on the device and browser.

How do I save a still?

Press Snapshot to download a PNG of the current frame.

What if permission is blocked?

Allow camera access in browser settings for this site, then Start camera again.
