Camera FPS & Resolution Test
Probe your camera at multiple resolutions (480p, 720p, 1080p, 4K) and measure the actual frame rate for each. All tests run locally in your browser.
This test probes your camera at four standard resolutions and measures the real frame rate the browser negotiates for each.
Built-in laptop webcams typically max at 720p–1080p, while dedicated USB cameras like the Logitech Brio can reach 4K (3840x2160) at 30 FPS.

We need access to your camera to test it. No video leaves your browser.
What Do Your Results Mean?
| Result | Range | Meaning |
|---|---|---|
| Good | 30+ FPS at target resolution | Your camera delivers smooth video at this resolution, suitable for calls and recording. |
| Warning | 15–29 FPS | Video is functional but may look slightly choppy in motion-heavy scenes or low light. |
| Bad | Below 15 FPS or resolution not supported | The camera cannot sustain this resolution. Use a lower resolution setting or check USB bandwidth. |
Common Issues and How to Fix Them
Camera does not support 4K resolution
Most built-in laptop webcams max out at 720p or 1080p. Only dedicated USB cameras (e.g., Logitech Brio, Elgato Facecam) typically support 3840x2160.
FPS is lower than expected at high resolution
USB 2.0 bandwidth limits throughput. Use a USB 3.0 port, improve lighting, and close CPU-heavy applications.
