About Free Online Screen Recorder
Record your entire screen, a single window or a browser tab, and optionally mix in your microphone, straight from the browser — no software to install and no account. When you finish, the recording appears right away for you to play back and download as a WebM video.
Everything is captured and saved locally using the browser's Screen Capture and MediaRecorder APIs; the video never leaves your device and nothing is uploaded. Recording stops automatically if you end sharing from the browser's own control.
Quick capture
Start recording → pick a tab → talk (mic on)
A downloadable .webm of the tab with your narration.
You choose what to share in the browser's picker; audio support depends on the browser.
Frequently asked questions
Do I need to install anything?
No. It runs entirely in your browser using the built-in Screen Capture API — no extension, app or sign-up.
Can it record audio too?
Yes. You can include your microphone, and system/tab audio when the browser offers it in the sharing dialog. Chromium browsers support this best.
Is my recording uploaded anywhere?
No. The video is captured and saved locally in your browser; it never leaves your device.
What format is the video?
WebM (VP9/VP8 with Opus audio), which plays in modern browsers and most players and can be converted if needed.
