Screen Recorder
Record a browser tab, window, or screen with optional microphone audio using native browser controls.
Uses the browser's native share picker
Record a tab, window, or screen locally
The practical guide
Let the browser decide exactly what may be shared.
The native picker cannot be bypassed. You choose a tab, window, or display and can stop sharing at any time.
Audio support varies
System or tab audio depends on browser, operating system, and the selected source. Microphone audio requires separate permission.
WebM is honest
The tool selects a supported WebM codec. It does not promise MP4 when native encoding is unavailable.
Privacy by architecture
Your screen recording stays in your browser.
The recording is not uploaded to any server. Screen and microphone tracks stop after recording, source sharing ends, or you leave the page.
Questions, answered
Frequently asked questions
Is the recording uploaded?
No. Recorded chunks stay in browser memory until you download or delete them.
Can I record system audio?
Sometimes. Availability depends on the browser, operating system, and source selected in the native picker.
Why is MP4 not available?
Most browsers expose WebM through MediaRecorder. This tool does not transcode to MP4.
Can I record one browser tab?
Yes when your browser offers a tab option in its native screen-sharing picker.
