What is an online screen recorder?
A browser-based recorder that captures your screen and optional system audio via the getDisplayMedia API. Input: screen share stream. Output: a video/webm file you can preview and download locally.
What format is the output?
video/webm. WebM is an open container format natively playable in Chrome, Firefox, and Edge.
Can it record system audio?
Yes. Check the "share system audio" option when you start sharing to capture both system audio and the screen.
Is there a recording time limit?
No fixed limit. Recording continues until you click Stop, with a live timer on screen.
Is my recording uploaded anywhere?
No. Everything happens locally in your browser. Your video never leaves your device.
Why can't I start recording?
The browser requires screen-sharing permission. Click "Start", choose a screen or window in the system dialog, and check "share audio" if you need sound.
