Camera Quality Check

A free test page that grades how you actually look on a video call - not the resolution printed on the box, but the frame rate your workstation really delivers plus your exposure and backlight. It catches the two most common complaints: "I look dark and washed out" (backlit, sitting in front of a window) and "I look laggy" (a 1080p camera dropping to 8 fps because the CPU is starved). Runs entirely in this browser; no video leaves your computer.

Read the Camera Quality Check guide for help reading the grade or fixing each problem.

Privacy: Every frame is analyzed locally in this browser tab and thrown away - the frame-rate count, the luminance histogram, and the backlight check all run on-device. No frame or image is uploaded, and the report contains only numbers. View source to verify.
