Screen Recorder

Records a tab, window or screen with optional microphone and system audio, and saves the WebM or MP4 locally.

Screen recording with the browser’s own APIs and nothing else: the operating system’s picker chooses what is shared, the browser writes the file, and it stays in this tab until you save it. No extension, no upload, no watermark.

🔒 Runs entirely in your browserscreenrecordvideocapture
The operating system's own picker decides what is shared, and this page only ever sees the stream you chose. Nothing is uploaded — the file is assembled here and saved by you.

How to use it

  1. Decide about audio first

    System or tab audio and the microphone are separate switches, and both have to be on before you start — they cannot be added to a recording already running.

  2. Choose a screen, window or tab

    The picker is the operating system’s, not this page’s. A single window is usually the better choice — it keeps notifications and other tabs out of the recording.

  3. Stop from here or from the browser bar

    Both finish the file properly. The browser’s own “Stop sharing” ends the track rather than the recorder, which is handled here so the recording is finalised instead of lost.

  4. Download before you leave

    The result is a Blob in this tab. Reloading the page discards it.

Common questions

What format do I get?

WebM in Chrome, Edge and Firefox — VP9 or VP8 with Opus audio; MP4 with H.264 in Safari. The page names the exact type it is using. WebM plays in browsers and most editors but not in older QuickTime or PowerPoint, so convert it if it is going to someone on a Mac.

There is no sound in the recording

System audio capture is not universal. Chrome and Edge offer it — for a tab everywhere, for the whole system on Windows — while Firefox and Safari largely do not, and the checkbox in the operating system picker has to be ticked as well. The microphone is a separate permission and is mixed in here.

Can I record on my iPhone?

No. iOS Safari has neither `getDisplayMedia` nor screen-capturing `MediaRecorder`, and no web page can work around that. Use the recorder built into the operating system.

How long can a recording be?

Until memory runs out — the file is assembled in the tab, so an hour of full-screen video is a large object to hold. For anything long, record in segments.
