Screen Recorder

Show someone how something is done, keep a bug that only happens once, save a call slide. Pick a window, press record, and get a video file — without installing anything.

00:00

    The video never leaves this device: it is not uploaded, and there is no account here to keep it in. The flip side is the same as with the voice recorder — the recording lives in the tab’s memory, and screen video is heavy: a minute is about twenty megabytes. Save it before you close the tab.

    Choose what you share with care: a whole screen shows notifications and open windows as they come.

    How to use

    1. Press record and choose in the browser window what to share: a tab, a window or the whole screen.
    2. Tick “record my voice” if you are going to explain what is happening.
    3. Press stop — or stop sharing in the browser panel — and download the video.

    Good to know

    Where the video is made

    In this tab. The picture goes from the screen straight into the browser's encoder and never touches a server, which is why a recording of your own work does not become somebody else's copy. The other half of that deal: until you press download, the video only exists in the tab's memory. Close the tab and it is gone — and screen video is heavy, about twenty megabytes a minute, so the tab does not hold it for long.

    Sound comes from two places, and not every browser gives both

    System sound — what the computer itself is playing — is shared by Chrome and Edge, and only when you pick a tab or the whole screen: a single window comes silent. Firefox and Safari never share it at all. Your voice is a separate stream, asked for separately. When both arrive they have to be mixed into one track, otherwise only the first would reach the file. The page says plainly what ended up in the recording, rather than promising sound in advance.

    Recording ends in two ways

    By the button here, and by the browser's own “Stop sharing” panel. The second one is easy to overlook when writing such a tool: the video track simply dies, and a page that is not watching for it keeps counting seconds on a dead stream and never assembles the file. Here that ending is caught, and the recording is saved exactly as if you had pressed stop.

    Frequently asked questions

    Is my recording uploaded anywhere?

    No. The screen is captured and encoded inside this browser tab. The file leaves your computer only when you send it somewhere yourself.

    Can I record on a phone?

    No, and no site can. Browsers on iOS and Android do not give web pages access to the screen at all — that is a decision of the operating system. Phones have their own built-in screen recorder.

    Why is there no sound in my recording?

    Most likely you shared a single window: system sound is only offered for a tab or the whole screen, and only in Chrome and Edge. In Firefox and Safari there is no system sound at all — the way round it is to record your voice instead.

    How long can I record?

    Up to thirty minutes, with a warning at twenty. The limit is memory: half an hour is already more than half a gigabyte sitting in the tab.

    Why is the file .webm and not .mp4?

    Because that is what browsers record natively — Safari being the exception, where you will get .mp4. A .webm file opens in every modern player and in any browser; if you need .mp4 specifically, our video converter turns it around in the browser too.
