About this tool

A screen recorder with nothing to install and nowhere to upload

This recorder uses your browser's built-in screen-capture engine — the same API behind video-call screen sharing — to record any screen, window or single tab, optionally mixed with your microphone for narration. Recording, encoding and saving all happen on your device: the video is assembled in memory and downloaded directly, so footage of your work never touches a server.

It is built for the everyday cases: a quick bug reproduction for a developer, a how-to for a colleague, a lecture snippet, a gameplay moment. Press record, pick the surface, do the thing, press stop, download. The output is a standard WebM file that plays everywhere modern and drops straight into our browser video editor if you want to trim it or export MP4.

  1. 1Choose whether to include microphone narration, then click Start recording.
  2. 2Pick what to share in the browser dialog — entire screen, one window, or one tab (tab mode can capture the tab's audio too).
  3. 3Do whatever you're recording; the timer shows elapsed time. Click Stop (or end sharing from the browser bar).
  4. 4Preview the result and download it as a WebM video — done.
What it can do
  • Record full screen, a single window, or a single browser tab
  • System/tab audio capture where the browser supports it
  • Microphone mixing for voice-over narration

  • Instant in-page preview before downloading
  • WebM output with file size shown — no quality-gated paywalls

Frequently asked questions

Is the recording uploaded anywhere?
No. Capture and encoding happen inside your browser using the MediaRecorder API, and the file downloads directly from memory to your device. Nothing is transmitted.
Why WebM and not MP4?
WebM is what browsers can encode natively in real time. It plays in Chrome, Edge, Firefox and most players; if you need MP4, import the file into our browser video editor and export from there.
Can I record system audio?
Tab sharing can capture that tab's audio in Chromium browsers; full-screen system audio is supported on some platforms (e.g. Windows Chrome/Edge) and not others — the share dialog shows an audio toggle when available.
Does it work on phones?
No — mobile browsers do not expose screen capture to web pages. Use a desktop browser; phones have built-in OS screen recorders instead.
Is there a time limit or watermark?
Neither. Length is limited only by your device's memory (long recordings produce large files), and the output is untouched — no branding, no trial banners.
