How to use Webcam Test
- Press Start the camera test and allow access.
- Read the panel: the resolution the camera is actually sending, the frame rate measured over two seconds, and the highest mode it supports.
- Switch cameras or ask for another resolution with the options; take a snapshot to check sharpness and colour.
Measured, not assumed
Webcams are often sold as “1080p” but deliver less in practice, because the browser, the USB connection or the lighting forces a lower mode. This test asks for the highest resolution and reports what the camera actually sends (the size of the video frames), together with the frame rate measured by counting frames for two seconds. In dim light many cameras drop from 30 to 15 fps to collect more light.
Where the browser exposes them (Chrome, Edge), the camera’s capabilities show the highest resolution and frame rate it supports. Choosing a resolution in the options asks for that mode; if the camera cannot provide it, the browser picks the nearest one, which you will see in the panel.
The mirror option only changes how the picture is shown to you (as in a selfie); other people in a call normally see you unmirrored. Snapshots are saved as PNG at full resolution.
Example
A laptop’s “HD” camera asked for the highest mode reports 1280 × 720 · 16:9 and 30 fps in daylight, 15 fps in a dark room. A 1080p USB webcam reports 1920 × 1080 · 16:9 and 30 fps, highest supported 1920 × 1080 at 60 fps.
Frequently asked questions
How do I test my webcam?
Press Start, allow camera access and you will see yourself. The panel shows the resolution and frame rate; if you see a black picture, another app may be using the camera.
Why is my webcam picture black or frozen?
Close other apps that can use the camera (Zoom, Teams, Skype, OBS), check for a privacy shutter or a camera key (often F8 or F10 on laptops), and check your system privacy settings. Then press Start again.
What resolution is my webcam?
The panel shows the resolution currently delivered and, in Chrome and Edge, the highest the camera supports. Choose a resolution in the options to see whether the camera can provide it.
Why is my webcam frame rate low?
Most webcams lower the frame rate in dim light. Add light in front of you; also try a different USB port (USB 3 for 1080p60 cameras).
Is the video recorded or sent?
No. The picture is shown only on this page. Snapshots are created on your device when you press the button.
Limitations
- Capabilities are not reported by every browser (Firefox and Safari show less).
- Frame rate is measured in the browser and can be limited by the page’s rendering, slightly below the camera’s rate.
- No microphone is used here; use the Microphone Test for audio.
