What a browser recorder captures
A browser recorder captures whatever you choose to share: the entire screen, one application window, or a single tab. It records what happens on screen, not the raw system stream — so minimize notifications and close anything you don't want on camera.
Pick the smallest source that works
Recording a window or tab instead of the whole screen keeps the file smaller and keeps notifications and pop-ups out of the frame. Record the full screen only when the demo genuinely needs several windows at once.
Record and convert in the browser
The Screen Recorder on this site records up to 10 minutes and converts the clip to a standard MP4 in the page — no install, no upload, no watermark. The recording stays on your device from start to finish.
When the screen comes out black
A black screen usually means the content is DRM-protected — streaming apps and some games block screen capture at the platform level. No recorder can get around that. If it happens on normal content, re-pick the source and check you shared the right window.
Good habits for clean recordings
Do a five-second test take to check the audio before the real recording. Plan the demo in steps so you don't ramble. And keep recordings under a few minutes per topic — short clips are easier to send and easier for viewers to follow.
