When you click Start Recording, your browser shows a picker with three scopes. Entire screen captures everything on a display, including notifications and anything you switch to, which is best for demos that move between apps. A specific window records just one application even if it falls behind others, so background clutter never appears. A single tab records only that browser tab, keeping the rest of your browsing and desktop private. The choice you make in that native prompt is exactly what gets recorded — the recorder simply captures whatever stream the browser hands it. Tab and window modes are ideal for clean walkthroughs and bug reports, while full-screen suits multi-app tutorials. Pick the scope that matches your goal in the share dialog, then start recording your screen here.

System audio — the sound playing from your computer — is exposed by browsers only in Chrome or Edge on Windows and ChromeOS. On macOS and Linux, the operating system does not let browsers route internal audio into a screen capture, so the System Audio option produces a silent track there. This is a platform limitation, not a tool restriction. To record your computer's sound on a Mac, install a virtual audio device such as a loopback driver that feeds system output back in as a selectable input. Microphone narration, by contrast, works everywhere the recorder runs, so you can still talk over your capture on any supported browser. If you only need your voice, choose the Microphone option before you start recording your screen and narrate as you go.

Video is captured at 30 frames per second, which is smooth enough for software demos, UI walkthroughs, cursor movement, and most on-screen motion without producing oversized files. For encoding, the recorder requests the VP9 video codec paired with Opus audio inside a WebM container wherever your browser supports that combination, giving strong visual quality at a comparatively small file size. If VP9 isn't available, it falls back to the browser's default WebM encoding so the recording still completes. Because everything is encoded locally using your browser's built-in media APIs, there is no quality loss from uploading or re-compressing on a server. After you stop, the page shows the finished clip's size in megabytes so you know exactly what you're saving. Start a capture to record at 30 fps WebM directly in your browser.

This recorder saves every capture as a WebM file, an open, royalty-free format that plays natively in Chrome, Edge, and Firefox and in most modern video editors and players. If you need MP4 — for example, to import into software that doesn't read WebM, or to upload somewhere that requires it — run the downloaded file through a video converter afterward. There's no quality penalty in keeping WebM when your destination already supports it, so only convert when something genuinely can't read the format. The downloaded file is named with a timestamp, like screen-recording followed by a number, so multiple captures never overwrite each other and stay easy to sort. Record and download your WebM clip here, then convert it only if a downstream tool requires MP4.

The tool itself imposes no time limit, watermark, or account gate, so a recording runs as long as you let it and an on-screen timer tracks the elapsed length while you capture. The real constraint is your device's memory: because the recorder is fully client-side, the entire clip is held in your browser until you stop and download it, so very long sessions on a low-memory device can eventually run out of space. For lengthy captures, recording a single window or tab instead of the whole screen and skipping audio you don't need keeps file size down. For most demos, bug reports, and tutorials this is never an issue. Click Start Recording whenever you're ready and stop and download whenever you're done.
