Screen recorder
Record tutorials, demos, bugs or presentations. Preview, trim and export as MP4 or WebM.
Record your computer screen directly from the browser without installing any software. Select a window, tab or the entire screen to capture video with or without microphone audio — perfect for creating tutorials, logging bugs, doing product demos or recording presentations.
After recording, preview the result, trim the start and end if needed, and export as MP4 (H.264) or WebM (VP9). The tool also lets you convert the recording to MP4 using FFmpeg via WebAssembly for maximum compatibility with players and social media.
Everything runs locally in your browser using native screen capture APIs (getDisplayMedia) and MediaRecorder. No data is sent to servers — your privacy is preserved from start to finish.
Frequently asked questions
Which browsers support screen recording?
Chrome, Firefox and Edge have native support. Safari (macOS 15+) has limited support. Screen recording is not available on mobile devices.
Can I record audio along with video?
Yes. You can enable the microphone to narrate your recording. The audio is mixed into the video in real-time by the browser.
Are my videos uploaded to the internet?
No. Recording, editing and conversion happen 100% in your browser. Nothing leaves your device.
How long can I record?
There is no built-in time limit, but long recordings consume RAM. We recommend pausing recordings longer than 30 minutes to avoid browser slowdowns.
What is the difference between output formats?
MP4 (H.264) is the most compatible format with players and social media. WebM (VP9) offers better compression while maintaining similar quality.
