Select two cameras and click Start Comparison to view them side by side with the webcam comparison tool. Compare video quality, colour accuracy, and resolution between your built-in laptop camera and an external USB webcam — or any two cameras connected to your device. All streams are processed locally; nothing is uploaded. Run a webcam test first to confirm both cameras are detected.
Camera A
Camera B
Compare your laptop's built-in camera to a dedicated USB webcam and see which delivers better colour accuracy and sharpness side by side.
Position cameras at different angles or distances and compare the live feeds simultaneously to find the best framing for calls or recordings.
Use the side-by-side view to spot differences in colour reproduction, sharpness, dynamic range, and low-light performance between two cameras.
The webcam comparison tool runs entirely in your browser using the standard WebRTC media API. No software, no account, no upload — both camera streams are handled locally and displayed side by side in real time.
Use the two dropdowns to choose which cameras you want to compare. Both selects are populated automatically when you land on the page — no permission prompt needed yet.
Your browser will request camera permission. Click Allow. Both selected cameras start streaming simultaneously into the left and right panels.
Look at colour accuracy, brightness, sharpness, and motion smoothness across both panels. Both feeds update in real time at the full frame rate each camera supports.
Click Stop Comparison at any time to end both streams. Change the dropdown selections and start again to compare a different pair of cameras.
Viewing two cameras side by side makes it easy to spot differences that are invisible when you only ever look at one feed at a time. The camera comparison view reveals several important performance factors at a glance.
Different cameras process colour very differently even when pointed at the same scene. A built-in laptop camera may shift skin tones towards yellow while a USB webcam produces cooler, more neutral tones. Side-by-side comparison immediately shows which camera's automatic white balance is closer to the real-world colours in your room.
Resolution alone does not determine sharpness — lens quality, compression, and sensor size all play a role. A compare webcams view lets you see whether a higher-megapixel camera actually looks sharper in practice, or whether a lower-spec camera with better glass produces a crisper image at the default resolution your browser negotiates.
The most dramatic difference between a budget built-in camera and a dedicated external webcam is usually how they handle low light. Use the webcam comparison tool to test this directly.
Reduce your room lighting and watch both feeds simultaneously. One camera may maintain reasonable brightness while the other becomes grainy or drops its frame rate as the auto-exposure compensates. This is the single most useful test the side by side webcam view enables.
In low light, cameras with smaller sensors produce more visible grain (digital noise). The comparison view makes it easy to see which camera applies better noise reduction or has a larger sensor that keeps the image cleaner without sacrificing detail.
getUserMedia API to access camera streams and pipes them directly into the two video elements on the page — nothing is stored.
