Webcam Tester is a free, browser-based webcam testing tool that lets you verify the live video size your webcam delivers in the browser.
A camera resolution test checks the actual video size your browser receives from a webcam. This matters because the advertised maximum resolution on a webcam box does not always match what the browser, USB connection, lighting, or app settings deliver in practice.
This page uses the same live webcam tester as our main camera tool, but focuses specifically on resolution-related intent.
Use the live preview, reported dimensions, and snapshots together before blaming the hardware.
Select the webcam you want to test, choose a higher target like 1080p, and compare the reported resolution value with what the browser shows in the information panel. If the reported dimensions stay lower, that is a sign the browser or device is not delivering full HD in the current setup.
If your "1080p" camera keeps reporting 720p, the usual culprits are dim lighting, USB 2.0 bandwidth, or the video app's own quality caps. The full diagnosis and fix ladder — including why Zoom, Google Meet, and Teams stream below your camera's spec — is covered in our guide on how to check webcam resolution and whether it is really 1080p.

It shows the video dimensions your browser receives from the camera, which is the most useful measurement for browser-based calls and web apps.
Resolution is only one factor. Focus, lighting, compression, exposure, and lens quality also affect sharpness.
Yes. If your system exposes more than one camera, switch devices and compare the reported output and snapshots.

Your camera isn't broken: video apps mirror your own preview on purpose, and everyone else sees you the right way around. Prove it in ten seconds with a snapshot of the raw feed, find the real mirror toggles in Zoom and Teams (Meet has none), fix flipped selfies, and catch the rare genuine flips from OBS and virtual cameras.
