A free online screen recorder that never uploads your video
Need to show a colleague a bug, record a lesson, capture a presentation or save a video call? The screen recorder records your entire screen, a single window or one browser tab straight from the browser — no software to install, no account, no watermark and no time limit beyond your device’s memory.
You can add your microphone for narration and, in Chrome and Edge, include the sound playing on your computer or in the tab, mixed into one track. A 3-second countdown gives you time to switch to what you are recording, you can pause and resume, and when you stop you get an instant preview with the duration, resolution and file size. Download it as WebM or, where your browser supports it, MP4. The video is processed entirely on your device and never sent to a server.
How to use the Screen Recorder
- Choose what to include: microphone, system or tab audio, and optionally a webcam overlay. Pick a quality and a format.
- Press Start recording. Your browser shows a picker — choose a screen, a window or a tab. Tick “Share audio” in the picker to capture sound.
- Allow the microphone if asked. After the countdown the red dot shows recording has started and the timer runs.
- Use Pause and Resume as needed. Press Stop (or “Stop sharing” in the browser’s bar) when you are done.
- Watch the preview, give the file a name and press Download recording.
Screen Recorder features
Screen, window or tab
Record the whole desktop, one application window, or a single browser tab — the tab option keeps notifications and other windows out of the video.
Mic and system audio together
Microphone and shared system or tab audio are mixed with the Web Audio API into one soundtrack.
Pause and resume
Skip the boring bits: paused time is cut from the recording and the timer.
Best available format
Detects what your browser can encode — WebM with VP9 or VP8, or MP4 with H.264 — and names the file with the right extension.
Webcam overlay
Optionally shows your webcam in a floating picture-in-picture window, so it appears on top of whatever you record.
Private and offline
Everything happens in your browser with MediaRecorder; nothing is uploaded, so it works with confidential screens.
Browser and device support
Screen capture uses the browser’s getDisplayMedia API, which is available on desktop and laptop browsers: Chrome, Edge, Firefox and Safari on Windows, macOS, Linux and ChromeOS. It is not available on phones and tablets — iPhone Safari and Android Chrome do not let web pages record the screen — so use the built-in recorder on those devices (Control Centre on iOS, the Screen record tile on Android).
| Browser | Screen / window / tab | System audio | Tab audio | MP4 output |
|---|---|---|---|---|
| Chrome, Edge (Windows, ChromeOS) | Yes | Yes (entire screen) | Yes | Recent versions |
| Chrome, Edge (macOS, Linux) | Yes | No | Yes | Recent versions |
| Firefox | Yes | No | No | No (WebM) |
| Safari (macOS) | Yes | No | No | Yes |
| Mobile browsers | No | — | — | — |
WebM or MP4?
WebM (VP9 or VP8 video with Opus audio) is the most reliable choice: every browser that can record supports it, it handles long recordings well, and it plays in Chrome, Edge, Firefox, VLC and YouTube uploads. MP4 (H.264 with AAC) is offered where the browser can encode it and is the better pick if you need to open the file on an iPhone, in Windows Media Player, in PowerPoint or in most video editors. If a program refuses a WebM file, convert it with a free tool such as VLC or HandBrake.
Quality controls the video bitrate: 2.5 Mbps keeps files small for sharing, 5 Mbps suits most tutorials, and 10 Mbps keeps small text crisp. A ten-minute recording at 5 Mbps is roughly 375 MB.
Tips for a good recording
- Record a tab rather than the screen when you only need one web page — the picture is sharper and nothing private can slip in.
- Check your microphone first with the mic test and your camera with the webcam test.
- Turn off notifications and close chat apps before recording the whole screen.
- Download straight away. The recording lives in the tab’s memory and is lost if you close or reload the page.
- Need just the sound? Pull the audio out afterwards with the video to audio tool, or turn a short clip into an animation with the video to GIF converter.
Screen Recorder FAQ
Is this screen recorder really free, with no watermark?
Yes. It is free, adds no watermark and has no fixed time limit. Very long recordings are limited only by your device’s free memory — a few hours at standard quality is usually fine.
Why can’t I record my screen on my phone?
Mobile browsers don’t allow web pages to capture the screen, so the tool explains this instead of failing. Use the recorder built into iOS (Settings → Control Centre → Screen Recording) or Android (Quick Settings → Screen record).
How do I record system audio?
In Chrome or Edge, tick “System or tab audio” here, then tick “Share audio” (or “Share tab audio”) in the browser’s picker. Whole-screen system audio is available on Windows and ChromeOS; on macOS and Linux only tab audio can be shared. Firefox and Safari record the microphone only.
Where is my recording saved?
Nowhere until you download it. The video stays in your browser’s memory and is never uploaded. Press “Download recording” to save it to your Downloads folder.
The screen picker never appears or recording is blocked — what do I do?
Check that the site is allowed to use screen capture in your browser’s site settings. On macOS, the browser itself must be allowed under System Settings → Privacy & Security → Screen Recording. On work computers, a policy may block screen sharing.
Can I record a Zoom, Teams or Google Meet call?
Yes — choose the meeting window or the whole screen, and share audio to capture the other participants. Always tell the people on the call that you are recording; in many places it is legally required.
