Screen Recorder: Record Your Screen Online, No Watermark
Record your screen, window, or browser tab with optional microphone audio. No upload, no watermark, no time limit.
Click Start recording and pick a screen, window, or tab
Tab or system audio is captured when your browser offers it in the share dialog. The microphone, if enabled, is mixed into the same track.
Capture a screen, application window, or browser tab straight from the page using the browser's native screen capture API. Tab or system audio is recorded where the browser provides it, and you can mix in your microphone for narration. Pause and resume mid-recording, watch a live preview, then download the result as a WebM file. Nothing is installed and nothing leaves your machine.
Screen Recorder is built on getDisplayMedia and MediaRecorder, the same APIs browsers use for video calls and built-in capture features. When you click Start recording, the browser shows its own picker where you choose an entire screen, a single window, or one tab. That picker is controlled by the browser, not the page, so the tool can never see anything you did not explicitly select.
Audio comes from two optional sources. The share dialog in Chrome and Edge offers tab audio (and system audio when capturing a full screen on Windows), and the microphone checkbox adds your voice. When both are present the tool routes them through a Web Audio graph and merges them into one track, so narration and tab sound end up in the same file instead of one replacing the other. The recorder negotiates the best available codec at runtime: VP9 where supported, then VP8, then the browser's default WebM profile.
While recording you get a live preview, an elapsed-time counter, and pause and resume controls. Stopping from the page or from the browser's own stop-sharing bar both end the recording cleanly. The finished clip plays back inline with its file size shown, and downloads as a .webm file with no watermark, account, or duration cap beyond your device's memory.

Choose what to capture
Tick Include microphone if you want narration, click Start recording, and pick a screen, window, or tab in the browser's share dialog.
- 2
Record with live preview
Watch the capture in a muted preview while the timer runs. Pause and resume as needed, then click Stop or end sharing from the browser bar.

Review and download
Play the finished recording inline, check its size and duration, then download it as a WebM file or start a new recording.
Record a bug report
Capture the exact clicks that reproduce a UI bug and attach the clip to a GitHub issue or Jira ticket instead of writing steps.
Make a quick demo for a teammate
Walk through a new feature with microphone narration and drop the file in Slack, no Loom account or upload step required.
Capture a tab with its audio
Record a web app, dashboard, or video element together with the tab's sound, something most OS-level recorders cannot isolate.
Create tutorial footage
Record raw screen footage for a course or YouTube tutorial, then trim or convert it with the other video tools on this site.
What format is the recording, and how do I get an MP4?
Recordings are saved as WebM, the only container MediaRecorder produces across browsers. WebM plays in every major browser and in VLC. If you need MP4 for editing software or messaging apps, run the file through the Video Converter tool on this site; that conversion also happens locally.
Is my screen recording uploaded anywhere?
No. The capture stream goes straight from the browser's screen capture API into MediaRecorder in your tab. The file exists only in your browser's memory until you download it to disk.
Does it capture system or tab audio?
It depends on the browser. Chrome and Edge offer tab audio for tab captures and system audio for full-screen captures on Windows. macOS browsers expose tab audio only. Firefox currently records video without tab or system audio, so use the microphone option there.
Does it work in Safari or on mobile?
Desktop Safari 16+ supports basic screen capture but not tab audio. iOS and Android browsers do not expose getDisplayMedia at all, so the tool shows a notice there; use the OS built-in recorder on phones instead.
Is there a watermark or time limit?
Neither. The output is exactly what MediaRecorder produces. The practical ceiling is RAM, since the recording buffers in memory: roughly an hour of 1080p screen content is usually a few hundred megabytes and fine on a typical laptop.
