- Check the live picture, then read the actual resolution and frame rate under the preview.
- If you have more than one camera, pick it from the Camera list, or request a higher resolution to see what it supports.
- Click Take snapshot to save a still image, and Stop to turn the camera off when you are done.

Why test your webcam first?
Few things derail a job interview, telehealth appointment or important meeting faster than “I can’t see you”. A thirty-second check before the call confirms that your browser has permission, that the right camera is selected and that the picture is clear and well lit. Because this test runs in the same browser you will use for most web-based calls, a working preview here is a strong sign that your camera will work there too.
Understanding the numbers
| Resolution | Name | What to expect |
|---|---|---|
| 640 × 480 | SD (VGA) | Older or very basic cameras; soft image on large screens |
| 1280 × 720 | HD (720p) | Typical laptop camera; fine for most video calls |
| 1920 × 1080 | Full HD (1080p) | Good external webcams; sharp detail for streaming and recording |
| 3840 × 2160 | 4K UHD | Premium webcams and some phones; mainly useful for recording |
Video-call apps usually send 720p or lower to save bandwidth, so a 4K camera mostly helps with recordings. Frame rate matters for smooth motion: 30 frames per second (fps) is the norm, and many cameras drop to 15 fps or lower in dim light because each frame needs a longer exposure. If your frame rate is low, add light rather than changing settings.
Why does my image look mirrored?
Most video apps show you a mirrored preview because that is what people are used to from a bathroom mirror; it makes moving your head left and right feel natural. The other people on the call normally see you unmirrored, so text on your shirt or a poster behind you reads correctly to them. Use the Mirror view switch to see both versions. Snapshots are saved exactly as shown.
Look better on camera
- Light from the front. Face a window or lamp. A bright window behind you turns you into a silhouette.
- Camera at eye level. Raise your laptop on a few books so the lens looks straight at you, not up at your chin.
- Clean the lens. Fingerprints cause a hazy, low-contrast picture.
- Frame yourself. Leave a little space above your head and show your shoulders.
- Close bandwidth-heavy apps so calls do not reduce your video quality.
Privacy
The camera stream is processed by your browser and shown only on this page. It is not recorded, uploaded or analyzed, and stopping the camera or closing the tab turns it off immediately; the camera light on your device should go out. Your browser remembers whether you allowed access, and you can revoke it at any time in site settings. Next, check your audio with the Mic Test.
Frequently asked questions
Is my video recorded or uploaded?
No. The video is shown only in your browser and is never sent to a server. Snapshots stay on the page until you download them, and closing the tab discards them.
Why does it say camera access was blocked?
Your browser or operating system denied permission. Click the camera or lock icon in the address bar to allow it, check your system privacy settings, then press Start camera again.
Why is the resolution lower than my camera’s rating?
Browsers start with a modest size to save power. Choose a higher option under Requested resolution; the camera then delivers the closest size it supports, which is shown as the actual resolution.
Why is my frame rate low?
In dim light many cameras lengthen each exposure, which lowers the frame rate. Add light in front of you. A busy computer or USB hub can also reduce it.
Can I test my phone’s front and back cameras?
Yes. On a phone, start the camera, then choose the other camera from the Camera list after granting permission.
