About this tool
Bug reports that nobody can reproduce, a quick how-to for a colleague, a demo for a client, a saved video call — a screen recording explains in thirty seconds what a page of text can't. This free online screen recorder captures your entire screen, a single application window or one browser tab at 30 frames per second, with system audio where your browser allows it and your microphone narration if you tick the box. A live preview shows exactly what is being captured, and the elapsed time and estimated file size update as you go.
There is nothing to install and no account to create: the page uses the screen-capture and MediaRecorder APIs built into Chrome, Edge, Firefox and Safari on desktop. Video is encoded on your own machine as WebM (VP9 or VP8 with Opus audio) and stays in your browser's memory until you press Download — it is never uploaded, so confidential dashboards and internal tools are safe to record. Recording stops automatically if you end sharing from the browser's own bar. Mobile browsers don't support screen capture, so on a phone use the operating system's recorder instead.
How to record your screen
- Optionally tick Also record my microphone, then click Start recording.
- In the browser's picker choose your screen, a window or a tab — enable Share audio if you want sound — and confirm.
- Press Stop (or end sharing in the browser bar), preview the clip and click Download.
Frequently asked questions
Does the recorder capture system audio?
It can, but it depends on what you share. Chrome and Edge offer a 'Share audio' checkbox in the picker: for a browser tab it is available on every platform, for the whole screen it works on Windows and ChromeOS, and sharing a single window never includes audio. Firefox and Safari do not capture system audio at all. Tick 'Also record my microphone' to add your voice regardless.
Why can't I record on my phone?
Mobile browsers do not expose the screen-capture API that this tool relies on, so Chrome and Safari on phones and tablets show a not-supported message. Use the built-in screen recorder instead: swipe down to Quick Settings on Android, or add Screen Recording to Control Center on iOS. On a laptop or desktop this page works in Chrome, Edge, Firefox and Safari.
How big will the recording be?
A typical 1080p recording at 30 frames per second comes out at roughly 15–40 MB per minute, depending on how much changes on screen — static slides compress far better than video playback or scrolling. The estimated size counter updates while you record, and the whole clip is held in your browser's memory, so very long sessions on low-memory devices are best split into parts.
How do I convert the WebM file to MP4?
WebM plays directly in Chrome, Edge, Firefox, VLC and uploads fine to YouTube, Google Drive and Slack. If a tool insists on MP4, open the file in VLC and use Convert/Save, run ffmpeg -i recording.webm recording.mp4, or use HandBrake. Browsers cannot write MP4 video themselves, which is why the recorder saves WebM.
Can I record just one window or a single browser tab?
Yes. When you press Start, the browser's picker lets you choose the entire screen, an application window or an individual tab. Picking a window or tab keeps notifications and other apps out of the recording, and tab capture is also the most reliable way to include audio from a video call or player running in that tab.
