Screen Recorder
Record your screen, window, or tab — with mic and system audio — free, no install, no upload
Screen recording isn't supported in this browser. Try the latest Chrome, Edge, or Firefox on desktop.
100% local — Capture and encoding happen right in your browser. Nothing is uploaded — the file only exists on your device until you download it.
Microphone permission was denied — recording continues without narration audio.
Screen, camera or both — recorded locally
Tab, window or full-screen capture with optional webcam overlay and microphone mixing, processed entirely inside your browser session.
Screen, window or tab
The browser's own picker lets you choose the whole screen, one window or a single tab before recording starts, so you capture exactly the area you need — nothing more.
Mic and system audio combined
Tick the checkboxes to mix your microphone with the system audio through a single audio graph, so a tutorial can carry both your voice and the app's sound in one synced file.
Pause, resume, review, download
Pause mid-recording and the timer stops counting; resume and keep going. Stop when done, preview the clip in the page, and download it straight to your device — the recording never leaves your machine.
Frequently asked questions
Where does my recording get uploaded?
Nowhere — screen capture and encoding both happen locally in your browser via the MediaRecorder API. The video file never leaves your device unless you choose to download or share it yourself.
Why is the download a .webm file instead of .mp4?
Chrome, Firefox and Edge record to WebM (VP8/VP9 + Opus) natively — it's the most reliable format for in-browser capture. Safari records directly to MP4. Either way, the file plays in any modern browser and video player; convert to MP4 anytime with our free Convert tools if you need that specific format.
Can I record my microphone and system audio together?
Yes — turn on both "System/tab audio" and "Microphone" before you start, and we mix them into a single audio track using the Web Audio API. Note that some operating systems (notably macOS, for a full-screen share) don't let browsers capture system audio at all — if that toggle has no effect, that's a browser/OS limitation, not this tool.
Capture internals worth knowing
- Sources — tab/window/screen selection plus a picture-in-picture camera overlay composited on a canvas.
- Audio mixing — system audio and microphone sum through a WebAudio graph with individual gain sliders.
- Encoding — WebM (VP9+Opus) by default; remux to MP4 afterwards with the convert tool if you need it.
- Privacy — nothing uploads; the recording exists only in memory until you save it.

What Is a Screen Recorder?
A screen recorder captures what happens on your display — your whole screen, one window, or a single browser tab — as a video file. This tool does it directly in your browser: no software to install, no account, no upload. You can include your microphone and system audio, optionally both, mixed into one track, pause and resume mid-recording, then preview and download the finished video the moment you stop. It is for tutorials, demos, bug reports and lessons — anyone who needs to show what happens on screen. The finished file is saved straight to your device, ready for the editing software, messenger or platform of your choice — no accounts, no cloud storage, no waiting.
What this tool can do
- 🖥️ Record the entire screen, a single window, or one browser tab
- 🎙️ Add your microphone to the recording
- 🔊 Include system audio, such as video or game sound
- 🔀 Mic and system audio mix into one audio track
- ⏸️ Pause and resume as often as you need during recording
- 🎞️ Preview and download the video right after you stop
When you would use it
- You record a software tutorial or a how-to guide for your audience
- You file a bug report and want to show the exact steps
- You record a video call or meeting for your notes
- You capture a moment in a game or a live page to share
Everything happens locally: the browser captures the display and audio with the built-in MediaRecorder API and assembles the file on your device — nothing is ever sent to a server. The recording is saved as WebM in most browsers, and Safari records MP4 natively. Two practical limits: capturing system audio depends on your operating system and browser allowing it, and when you share a browser tab, that tab needs to stay open during the recording.
