A free screen recorder in your browser
There are many reasons to record your screen: showing a colleague how to use software, recording a lesson or presentation, documenting a bug for support, or saving a live webinar. This tool records straight from the browser using the built-in Screen Capture API — no installs, no watermark and no time limit.
How to record
- Enable “System / tab audio” to capture video sound and “Microphone” for your narration.
- Click “Start recording” and choose what to share: the entire screen, an app window or a browser tab.
- When sharing a Chrome tab, tick “Share tab audio” in the picker.
- Click “Stop recording” (or the browser's “Stop sharing” button) when done.
- Watch the preview and click “Download video”.
Video format
Chrome, Edge and Firefox save recordings as efficient WebM; Safari saves MP4. WebM plays in browsers, VLC and uploads fine to YouTube. If you need MP4 for a specific program, convert it with free tools like HandBrake.
Tips for professional recordings
- Turn off notifications and close unnecessary apps first.
- Record a single window instead of the whole screen to keep your desktop private.
- Use a headset microphone for clear sound without echo.
- Choose “High” quality for tutorials and “Standard” for long recordings to save space.
Privacy
Your video is never uploaded. It's recorded into browser memory and downloaded directly to your device, so you can safely record confidential or internal content. To record only your voice, use the Voice Recorder.
Tips for professional screen recordings
- Clean your screen: silence notifications, close unneeded tabs and hide personal information before starting.
- Record one window or tab instead of the whole screen when possible — it keeps focus and reduces file size.
- Prepare what you'll say: short written bullet points cut hesitation and mistakes.
- Test audio: record 10 seconds and listen before a long take.
- Keep it short: 2–5-minute videos get watched to the end far more often.
About WebM
Browsers usually save recordings as WebM, an open format played directly by Chrome, Firefox, Edge, VLC and YouTube. If a program needs MP4, convert it with free tools like VLC or HandBrake. For audio only, use the Voice Recorder.
Frequently Asked Questions
Is there a time limit?
No, but very long recordings use device memory, so consider splitting sessions over an hour.
Does it work on mobile?
No — mobile browsers don't support screen capture yet. Use your phone's built-in screen recorder.
Why is there no sound?
Make sure “System / tab audio” is on and “Share audio” is ticked in the browser picker. On macOS only tab audio can be captured, not full system audio.
Is there a watermark?
No. The video is clean and completely free.
What format is the file?
WebM in Chrome, Edge and Firefox; MP4 in Safari.
