Test Webcam for Max Resolution & FPS

The webcam tester scans your webcam for supported resolutions and the max fps it can capture those resolutions at.

Check Picture Quality

You can switch to any supported resolution and check the picture quality for clarity, colour, smoothness.

Export Results

The results can be exported as csv, markdown, xml or json. The results include the camera name, browser and all tested resolutions.

Secure & Private

The webcam tester runs locally in your browser. No video, picture or metadata is uploaded to our servers. When you’re done testing, close the webcam stream.

Free Online Tool

No account, downloads, or software installation required. The code can be inspected in Webmaster Tools and GitHub.

Test Multiple Webcams

The webcam tester works with multiple webcams including front/back cameras on mobile devices.

Is Your Webcam Not Working?

Camera Permission Not Granted

Camera access might be blocked at the OS or browser level. You need to reset permissions for the domain in the browser and/or check if the browser has been granted camera access at the OS level.

Another App Is Already Using the Camera

On Windows, software like Zoom, Teams, OBS or other browsers can get exclusive access to the webcam, making the camera unavailable to the current browser.

Wrong Camera Selected (Multiple Cameras)

If multiple cameras are available—for example, a built-in webcam, an external webcam, an OBS virtual camera, or an iPhone connected through Continuity Camera — the wrong one may be selected.

Webcam Doesn’t Support Certain Resolutions

Not all webcams support all resolutions. Most webcams don’t support 4K for example. Unsupported resolutions will be marked accordingly in the results.

Poor Lighting Reduces FPS, Increases Size.

Poor lighting conditions will lead to grainy/noisy video, less detail and colors, lower frame rate and increased size if the stream is recorded as a video file.

Grainy, Blocky, Noisy Image

Make sure your webcam is not in use by another app. The other app could dictate a lower resolution or frame rate. The resolution might be higher than what your webcam supports comfortably.

Blurry Image

A dirty webcam lens will impact the webcam’s ability to focus. Make sure your lens is clean.
