Questions and answers

No. The recorder runs directly in a supported web browser. There is no extension, no desktop app and no driver to install.

No. The recording is processed locally in your browser and is not sent to the application's server. The video data is held in the tab's memory as a Blob and released when you download it, delete it, or close the tab.

No. There is no sign-up, no sign-in and no profile. Open the recorder page and press start.

Yes, provided you allow it. The device stays closed until the switch is on and a capture actually begins, so simply visiting the page never triggers a request.

Yes. Turn the microphone on and a picker appears next to the switch if more than one is attached. The same applies to cameras. Device names show as "Microphone 1", "Microphone 2" and so on until you have recorded once, because browsers hide the real names until you have granted access at least once.

Turn the microphone on and press "Test microphone" before you start. A level meter appears and tells you when it hears you. The microphone is released as soon as you stop the test, and nothing from it is captured or stored. During the recording itself the same meter stays visible, and it warns you if the microphone goes silent for several seconds.

Yes, if you grant camera permission. The webcam is drawn into the recording as a movable overlay, so the saved file contains both the screen and the camera in a single video track.

Straight away. Press "Start recording", choose a screen, window or tab in the dialog your browser opens, and recording begins the moment you confirm. If you need a second to get ready, press pause and resume when you are set.

Not within the page. Choose a single window or browser tab in the dialog your browser opens, which is the closest thing to it, or crop the downloaded file in a video editor.

It varies by engine and platform. Chromium browsers let a shared tab bring its sound along, and Windows extends that to a full display. Firefox and Safari offer neither. Your microphone, by contrast, is recorded anywhere. If a recording came out silent, work through the four causes.

A WebM file in browsers that record WebM, which covers Chrome, Edge and Firefox. Safari records MP4 instead. The recorder asks MediaRecorder what it actually supports and uses the first working option rather than promising a format the browser cannot produce.

There is no time limit built into the app. The practical limit is your device: the recording is held in memory, so very long or very high-resolution captures will use a lot of RAM. For recordings beyond roughly half an hour, save often rather than recording one enormous file. How long a recording can be has the numbers.

No. This is a recorder, not an editor: you record, preview and download. Trimming or cropping in the browser means re-encoding the whole video, which takes about as long as the clip runs, so it is quicker to do it in whatever editor you already use.
