Free Online Webcam Checker
Test your webcam: FPS, resolution, microphone, autofocus, lens distortion, rolling shutter, flicker, chromatic aberration, vignetting, dynamic range, white balance, etc.

Use the Dead Pixel Test mode and click "Launch Fullscreen Test". It cycles through solid red, green, blue, white, and black. Dead pixels appear as dots that don't change color. Stuck pixels may glow red, green, or blue on the wrong background.
Select Backlight Bleed test and launch fullscreen. The screen goes pure black. In a dark room, look at the edges and corners — any visible glow is backlight bleed. This is most common on IPS and edge-lit LCD panels.
The Response Time Test shows a fast-moving white ball on a black background. If you see a ghost trail behind it, your monitor has slow pixel response. Gaming monitors (1–5ms) show almost no trail. Basic office monitors (8–12ms) may show noticeable ghosting.
Select the Resolution Test mode and start your camera. The tool displays actual output dimensions (width × height) and labels it as 4K, 1080p, 720p, etc. Use the snapshot feature to save a full-resolution image to compare quality.
30 FPS is the standard for webcams. 60 FPS is ideal for streaming and gaming content. Below 15 FPS will look choppy. Use the FPS Test mode to measure your camera's actual real-world frame rate over time.
Select Microphone Test mode. The tool requests mic permission separately and shows a live audio level bar, peak dB, average dB, and noise floor measurement. Great for checking audio before Zoom calls, YouTube recordings, or podcasts.
The Gradient Test shows a smooth transition from black to white and across colors. If you see distinct "steps" or "banding" instead of smooth transitions, your monitor may have limited color depth (6-bit dithering instead of true 8-bit). High-quality monitors will show perfectly smooth gradients.
