You'll choose a tab, window or full screen after clicking start.
Desktop only – phone browsers don’t allow web screen recording. For computer sound, pick a Chrome/Edge tab and tick “share tab audio” in the dialog.
Quick answer: Click Start recording, pick what to share (this tab, a window, or your entire screen), and optionally include your microphone. When you stop, the video previews instantly and downloads as a WebM file – no watermark, no time limit, and the recording never leaves your computer.
This recorder uses your browser's built-in screen-capture engine (the same one behind screen sharing in Google Meet), which means true no-install recording: choose a browser tab, an application window or the whole desktop, add your microphone narration if you want, and everything is encoded on your own machine. Because nothing uploads anywhere, there are no file-size fees, no queues and no privacy worries – the video exists only on your device.
Recordings save as WebM – the web's native video format that plays in Chrome, Edge, Firefox, VLC and uploads fine to YouTube. If a workflow demands MP4 (some editors, WhatsApp), run the file through our free video compressor, which converts to MP4 while shrinking it. For tutorial makers: pick “tab” capture when recording a website (sharpest text and it hides your bookmarks), and “window” for a single app without desktop clutter.
How to record your screen online
- Choose whether to include your microphone (for narration) using the checkbox.
- Click Start recording and pick a tab, window or entire screen in the browser dialog – tick “share tab/system audio” there if you want computer sound.
- Do your thing – the timer runs and you can Pause anytime.
- Click Stop (or the browser's stop-sharing bar) – the video previews instantly.
- Hit Download to save the WebM file. Convert/compress to MP4 with our video compressor if needed.
Why use the GadgetsFocus screen recorder?
- Record a tab, a single window or the full screen – your choice each time.
- Optional microphone narration mixed in, plus tab/system audio where the browser offers it.
- Pause and resume mid-recording.
- No watermark, no time limit, no sign-up – and no upload: the video is created on your device.
- Instant preview and one-click download (WebM, ready for YouTube/editors).
Honest limitations
- Works on desktop browsers (Chrome, Edge, Firefox, Safari 16+); phone browsers don't allow web screen recording – use your phone's built-in recorder there.
- System/tab audio capture depends on the browser: Chrome and Edge offer “share tab audio” (and system audio on Windows); Firefox and Safari record mic only.
- Output is WebM; a few apps want MP4 – convert with our video compressor tool.
- Very long 4K recordings create large files and use RAM while recording – for multi-hour sessions, a desktop app like OBS is the better tool.
Frequently asked questions
Is there a watermark or time limit?
Neither. The recording is produced by your own browser on your own machine, so there's no service to stamp watermarks or enforce limits – file size and length are bounded only by your disk and RAM.
How do I record with sound?
Two audio sources exist: your microphone (tick the checkbox before starting) and the computer's own sound – for that, choose a Chrome/Edge tab and enable “Also share tab audio” in the picker dialog (Windows Chrome/Edge can also share full system audio when capturing the entire screen). Both can be on at once and are mixed together.
Where does my recording go – is it uploaded?
Nowhere but your device. Capture and encoding happen locally; clicking Download saves the file straight from your browser's memory to your Downloads folder. We never see a single frame.
Why is the file .webm and how do I get MP4?
WebM is the format browsers encode natively – it plays in modern players and uploads to YouTube directly. For MP4, drop the file into our free online video compressor: it converts and shrinks it in one step, also entirely in your browser.
Can I record my phone's screen with this?
Mobile browsers don't expose screen capture to websites yet. Use the built-in recorder instead: iPhone – Control Center → Screen Recording; Android – Quick Settings → Screen record. This tool shines on laptops and desktops.
