Free Online Screen Recorder

Record any tab, window, or your entire screen — with optional microphone audio. Nothing is uploaded; the video is saved straight to your device.

No install No sign-up No watermark No time limit
Ready — click “Start recording” and choose what to share.

Tip: when picking a browser tab, enable “Share tab audio” to capture sound from videos, calls or games playing in that tab. Everything stays on your device — no server, no upload.

How to record your screen

1. Choose audio

Pick microphone only if you want narration, or none for a silent capture.

2. Start recording

Your browser shows a picker — choose a tab, an app window, or the whole screen.

3. Stop & download

Hit Stop, preview the result, and download it as MP4 or WebM. No watermark.

Frequently asked questions

Is this screen recorder really free?

Yes — no sign-up, no watermark, no time limit, no payment. It uses the screen-recording capability already built into your browser.

Is my recording uploaded anywhere?

No. The recording is made and saved entirely on your device. This page has no server and never sees your video.

WebM or MP4 — which should I pick?

WebM is the format browsers record natively and always works. MP4 is repackaged in your browser for better compatibility with phones and video editors. If the MP4 option fails on your device, use WebM.

Which browsers support screen recording?

Chrome, Edge, Firefox and Opera on desktop. Safari and most mobile browsers don't support it yet — on phones, use a native screen-recorder app instead.

Can I record a video call or a game?

Yes. In the picker, choose the tab or window running it. For the sound of a video or game, select the tab and turn on “Share tab audio”. To narrate with your voice, pick Microphone audio above.
