About CamTestKit

CamTestKit is a free set of camera tests that run entirely in your web browser. It started as a better webcam test — one that measures what a camera actually delivers rather than what its settings claim — and grew into a toolkit for benchmarking any camera against your screen.

What you can do here

• Webcam test: real frame rate, native resolution, frame timing, color space and full-resolution snapshots.
• Test patterns: frame-locked flicker, rolling shutter and shutter-speed targets, resolution charts, a Siemens star and color bars.

Private by design

All processing happens on your device. Camera frames are analyzed in memory by your browser and are never uploaded, recorded or stored by us. See the privacy policy for details.

Accuracy and limitations

Measurements depend on your browser, operating system and display. Frame rates are counted frame by frame where the browser supports it; screen-based timing tests are limited to one display refresh period; resolution tests are limited by your monitor’s pixels. Each tool explains its method and limits so you can judge the results.

How CamTestKit is funded

The site is supported by advertising and by affiliate links: if you buy a recommended product through a link, we may earn a commission at no extra cost to you. Recommendations never change the test results.
