What does Webcam Test do?
Confirm your webcam works before a call. It shows a live preview, lists every camera attached, and reports the actual resolution and frame rate the browser is receiving, which is often lower than the camera claims. Nothing is recorded and no video leaves the page.

Frequently Asked Questions
Is my video uploaded or recorded?
No. The stream is displayed directly in this page by your browser and never touches a server. Closing the tab ends the stream, and the snapshot button writes a file only to your own device.
Why does the browser say my camera is blocked?
Permission was denied for this site at some point, or another application is holding the camera. Clear the site permission in the padlock menu of the address bar, close other video apps, and reload.
Why is my resolution lower than the camera supports?
Browsers negotiate a stream rather than always taking the maximum. Lighting matters too — many webcams drop frame rate in dim rooms to keep the exposure usable, which reduces the effective quality.
Why is my image mirrored?
Video apps flip the preview so it behaves like a mirror, which feels natural to the person on camera. The people watching you see the unflipped image. The mirror toggle here lets you check both.
