Webcam Test
Test your webcam directly in the browser. Check camera resolution, frame rate, and image quality. Take snapshots and switch between cameras if you have more than one.
Ready to test your camera
Click the button below to grant camera access. Your video stays in the browser and is never uploaded or stored.
How to use this test
- Click Start Camera and allow camera access when your browser asks.
- Check the live preview for image quality, focus, and exposure.
- Review the resolution, aspect ratio, and FPS readings below the preview.
- Use the Mirror toggle to flip the image horizontally, which is the default for video calls.
- Click Take Snapshot to capture and download a still frame from the camera.
- If you have multiple cameras, use the dropdown to switch between them.
Testing guide
How to test your webcam
This webcam test opens your camera directly in the browser so you can check video quality, resolution, and frame rate before a call or recording. Nothing is uploaded or stored. The preview stays on your device, and you can take snapshots, switch between cameras, and mirror the image.
Best for
- Checking that a new, built-in, or USB webcam produces a clear image before a video call or interview.
- Finding out the actual resolution and frame rate your camera delivers, which is often lower than advertised.
- Comparing image quality between a laptop built-in camera and an external USB webcam.
How to run the test
- 1Click Start Camera and grant permission when the browser asks for camera access.
- 2Check the live preview for focus, exposure, and overall image quality.
- 3Read the resolution, aspect ratio, and FPS stats below the preview to see what your camera is actually delivering.
- 4Take a snapshot to inspect a still frame more closely, or download it for reference.
How to read the result
A resolution of 1920x1080 at 30 FPS is standard for a good USB webcam. 720p is typical for a basic laptop camera.
Low FPS, such as 15 or below, usually means the camera is in a low-light mode, USB bandwidth is constrained, or another app is competing for the camera.
A blurry or washed-out image with correct resolution usually points to a dirty lens, poor lighting, or a fixed-focus camera at the wrong distance.

Frequently asked questions
Is my webcam video uploaded anywhere?
No. The video stream stays entirely in your browser using the getUserMedia API. Nothing is sent to a server, recorded, or stored. Snapshots are generated locally and only saved if you choose to download them.
Why does my webcam show a lower resolution than advertised?
Many webcams advertise interpolated or maximum still-photo resolution rather than their actual video resolution. USB bandwidth, the browser, and the operating system can also constrain the resolution below what the sensor supports, especially over USB 2.0.
Why is my webcam FPS so low?
Common causes are low ambient light, which forces the camera to use a longer exposure per frame, USB bandwidth limitations when other USB devices share the same controller, background apps using the camera simultaneously, or an older webcam with limited hardware capability.
Can I use this test on my phone?
Yes. Mobile browsers support getUserMedia, so you can test both front and rear cameras. Use the camera selector dropdown to switch between them. On some phones you may need to grant camera permission in your device settings as well as in the browser prompt.
Why is the image mirrored by default?
Mirroring matches what you see in a physical mirror and what video call apps show you. It feels natural when checking your own appearance. The actual video sent to other people in a call is usually not mirrored. You can toggle it off to see the un-flipped image.
My camera works in other apps but not here. What should I check?
Make sure no other app has an exclusive lock on the camera. Check that your browser has camera permission enabled in its site settings. On macOS, verify that the browser is listed under System Settings, Privacy and Security, Camera. Restarting the browser can also release a stuck camera lock.
