About the screen recorder

The screen recorder uses the browser’s Screen Capture and MediaRecorder APIs to record a tab, window, or your whole screen — optionally with your microphone — and saves a WebM video you can download. Everything happens locally; no video is ever uploaded. Note that screen capture is a desktop-browser feature and is not available on iOS.

  2. 2In the browser dialog, choose the screen, window, or tab to share and confirm any audio option it offers.
  3. 3Stop from Toolbay or the browser sharing control, preview the WebM recording, then download or discard it.

Frequently asked questions

Can the recording include system audio?
Only if the browser and operating system offer audio for the surface you select. Tab audio is commonly available; full-system audio support varies.
What does the microphone option add?
It requests a separate microphone track and combines it with the display tracks. If microphone permission fails, screen recording can continue without that track.
Which file format is downloaded?
The tool records and downloads WebM using the first VP9, VP8, or generic WebM configuration supported by the browser.
Why is screen recording unavailable on my device?
The feature requires getDisplayMedia and MediaRecorder. Some mobile browsers and embedded webviews do not expose screen capture.
