Screen Recorder

How to use it

1. Choose the File format, and tick Sound from the shared screen or tab and My microphone if you want them.
2. Press Start recording, then choose a screen, a window or a browser tab in the browser's prompt.
3. Press Stop recording when you are done, or stop sharing in the browser.
4. Press Download recording to save the file.

What the browser asks

Screen capture always goes through the browser's own prompt, where you choose a whole screen, a window or a tab. While the screen is shared, the browser shows an indicator. Sharing stops when you press Stop recording, when you stop sharing in the browser, or when you leave the page. A page can ask for screen capture only on a secure connection (HTTPS), as the MDN article on getDisplayMedia describes.

Sound

Sound from a shared tab or screen is included only where the browser offers it in its prompt. Your microphone is added only when you tick My microphone. The browser mixes both sounds into one audio track, so a loud shared sound can drown out a quiet voice; if the voice is too quiet, lower the sound on the shared page.

Formats and phones

WebM, with VP9 or VP8 video and Opus sound, is the usual choice. MP4 is used when the browser can record it, and otherwise the page uses WebM and says so. Phones and tablets do not allow their browsers to capture the screen, so the page explains this instead of starting a recording. Use a computer for screen recording.
