Record Your Screen Without Installing Software
Whether you need to record a bug on a website to send to a developer, capture a Zoom presentation, or record a quick video tutorial for a coworker, installing bloated desktop software like OBS or Camtasia is frustrating. Our Online Screen Recorder leverages native browser APIs to capture your screen instantly. With one click, you can record your entire desktop, a specific application window, or just a single browser tab, all while capturing your microphone and system audio.
The Security of the WebRTC Protocol
Allowing a website to record your screen sounds dangerous, but modern browsers have solved this elegantly:
- The Browser Sandbox The tool uses the `getDisplayMedia` API. The website itself cannot see your screen. The browser (Chrome/Edge) intercepts the request and forces a secure pop-up. YOU must manually select which window to share. The website only receives the video stream you explicitly authorize.
- 100% Local Processing Your recording is NEVER uploaded to a cloud server. The video is rendered and saved entirely within your computer's temporary RAM. When you click 'Download', it saves locally to your hard drive, ensuring massive corporate privacy.
- System Audio vs. Microphone You can choose to record your Microphone (your voice), the System Audio (the sound of the video playing on your screen), or both. *Note: Apple strictly limits recording System Audio on Macbooks for copyright reasons.*

Frequently Asked Questions
Why is the exported video in WEBM format instead of MP4?
Browsers natively encode video streams using the VP8/VP9 codec inside a WEBM container because it is open-source and incredibly efficient for live-rendering. If you strictly need an MP4, you can run the final file through our WEBM to MP4 converter.
Can I record a Netflix movie?
No. Streaming platforms like Netflix, Hulu, and Disney+ use DRM (Digital Rights Management) called Widevine. If you try to screen record a Netflix tab, the browser's DRM protocol will intervene and record a completely black screen to prevent piracy.
What happens if I close the tab while recording?
Because the video is being held in your browser's temporary memory, closing the tab or refreshing the page will instantly and permanently delete the entire recording. Always hit 'Stop' and download the file first.
