Webcam Test: Check Camera, Resolution, Frame Rate and Mic in Browser
Start the camera and see right away whether the picture is right: the webcam test shows resolution, frame rate and aspect ratio, checks the microphone level and runs entirely in your browser.

Check camera and microphone locally before the meeting
The test spares you the moment when a video call begins and the picture is black, choppy or mirrored. You start the camera, see yourself live and check which resolution and frame rate it actually delivers, not what the box promises.
The readings come from the video stream: the frame rate counts the frames delivered per second if your browser supports that; otherwise it shows the value reported by the camera. The resolution is the size the browser actually receives. If the frame rate drops, for example in low light, or the resolution stays below the level you chose, you see it and can change the lighting, the connection or the camera setting.
With the microphone level you check in one go whether your microphone delivers sound, and the snapshot lets you look at framing, background and lighting at your leisure. Everything runs in the browser; nothing is sent. What your network and the meeting app make of it is something a local test cannot show.
How it works
- 1
Start the camera
Click "Start camera" and allow access in your browser's prompt.
- 2
Choose camera and resolution
If you have several cameras, pick the right device and set the resolution you want, for example 1280 × 720 or 1920 × 1080.
- 3
Check the values
Check resolution, frame rate and aspect ratio, test the microphone level and switch the mirroring if needed.
- 4
Save a snapshot
Take a test picture and download it as a PNG to judge framing and lighting at your leisure.
Typical uses
Before the video call
Check camera, lighting and microphone five minutes before the meeting instead of during the call.
New webcam
After plugging it in, see whether the camera is detected and which resolution it really delivers.

Good to know
- The test shows resolution, frame rate, aspect ratio and device name; resolution selectable from 640 × 480 to 3840 × 2160 or automatic. The frame rate is counted if the browser supports it; otherwise it shows the reported value.
- Free, no account and no AI; picture and sound stay in your browser, nothing is recorded or uploaded. Mirroring is a display option, on by default and switchable for each camera.
- As a guideline, 720p at 30 frames per second is fine for video calls; below 15 frames per second the picture looks choppy.
- Low light can lower the frame rate and make the picture grainy: light from the front rather than behind, camera at eye level, clean the lens.
- If the camera does not start, it is often in use by another program, or access is blocked in the browser or in the system settings (Privacy → Camera).
Frequently asked questions
Why can't I see a picture?
Usually the permission is missing: click the camera icon in your browser's address bar and allow access. If the picture stays black, check the lens cover, the camera key on the laptop and whether another program such as Zoom or Teams is currently using the camera.
Is my picture being recorded?
No. The video runs only in your browser; nothing is saved or sent to ChatX. The snapshot is created on your device too. "Stop" ends the camera picture; you end the microphone test with another click on its button, and leaving the page ends both.
Which resolution and frame rate are enough for video calls?
1280 × 720 at 30 frames per second is a common guideline for meetings; for recordings, 1920 × 1080 makes sense. Below 15 frames per second it gets choppy; one possible cause is too little light, another a slow connection.
Why is the resolution lower than stated?
The resolution you choose is a request; the browser takes the nearest level available. Without a setting, many cameras only deliver 640 × 480; select 1080p or 4K specifically. If the camera still delivers less, a note says so below the picture; a direct USB connection instead of a hub and more light often help.
Why is my picture mirrored?
The preview is mirrored by default, like a mirror. Others usually see you the right way around in a video call. Use "Mirror" to switch this; the setting stays even after switching cameras, and the snapshot follows it.
Can I test the microphone too?
Yes. Click "Test" next to the microphone and speak: the bar shows the level. If it stays empty, a different microphone is selected in the browser or system, it is muted, or the webcam has no microphone at all. The tool itself offers no microphone selection; you make that in the browser or system settings.
Does the test work on a phone?
Yes, in current browsers on Android and iPhone. With several cameras you choose front or rear from the list. Mirroring stays as set; for the rear camera, switch it off if needed.
