What Is a Screen Recorder?
A screen recorder captures everything happening on your display — your browser tab, an application window, or your entire screen — and saves it as a video file. This tool runs entirely in your browser using the native MediaRecorder API, so nothing is uploaded to any server and no software installation is required.
This screen recorder supports microphone narration, webcam overlay for picture-in-picture style recordings, and system audio capture (in supported browsers). It's ideal for product demos, bug reports, tutorials, walkthroughs, and quick video messages — the exact use cases that tools like Recordly, Loom, and OBS serve, but with zero setup.
Key Features
- → Screen, Window, or Tab Capture. Choose what to record — your entire screen, a specific application window, or just a single browser tab. The browser's built-in picker handles the selection.
- → Microphone + System Audio. Record your voice alongside the system audio from the captured source. Perfect for narrating demos, recording meetings, or creating tutorials with commentary.
- → Webcam Overlay. Enable your camera to appear as a picture-in-picture bubble over the screen recording. Great for adding a personal touch to walkthroughs and presentations.
- → Countdown Timer. Set a 3, 5, or 10-second countdown before recording begins, giving you time to switch windows and prepare.
- → Pause & Resume. Pause your recording mid-session and resume when ready — no need to start over or stitch clips together.
- → Instant Playback & Download. Review your recording immediately in the browser with full playback controls, then download the WebM file directly to your device.
How to Use This Screen Recorder
- Configure your options — Toggle microphone and webcam overlay on or off. Choose a countdown delay (None, 3s, 5s, or 10s).
- Click "Start Recording" — Your browser will ask what you want to share: a tab, a window, or your entire screen. Select your target and confirm.
- Record your content — The timer tracks your recording duration. Use Pause/Resume as needed.
- Stop and review — Click Stop to end the recording. Preview the video immediately in the built-in player.
- Download your video — Save the recording as a WebM file. All recordings stay in your browser — nothing is uploaded.
Tips and Best Practices
- → Close unnecessary tabs. Fewer tabs means more memory available for smooth recording, especially for longer sessions.
- → Use tab capture for browser demos. Capturing a specific tab gives the cleanest result — no address bar, no system notifications, and system audio is included automatically.
- → Set a countdown. A 3 or 5-second countdown gives you time to switch to the window you want to record and compose yourself before the capture begins.
- → Convert to MP4 if needed. WebM works great on the web, but if you need MP4 for editing or sharing, use a free converter like CloudConvert or HandBrake.
