How to record your screen
- Choose whether to include tab or system audio, your microphone for narration, and a round webcam bubble in the corner.
- Pick the format and quality, and press Start recording. Your browser asks which screen, window or tab to share.
- After the countdown, do your demo. Pause and resume as needed, then press Stop (or the browser's "Stop sharing" button).
- Preview the video and download it. There is no time limit, watermark or sign-up.
How it works and what is supported
The recorder uses the browser's built-in Screen Capture API and MediaRecorder, so the video is encoded on your computer and never sent to a server. Chrome and Edge can record a tab, a window or the whole screen, including tab audio (and full system audio on Windows and ChromeOS). Firefox and Safari record screens and windows but generally without system audio; add the microphone instead. All browsers produce WebM, and Safari and recent Chrome and Edge versions can also save MP4, which is easier to share and edit.
Mobile browsers do not allow web pages to capture the screen: use the screen recording built into iOS or Android. For long recordings, keep an eye on free disk and memory; one hour at High quality is roughly 2–3 GB. If you need a smaller file afterwards, use the video compressor, or the video trimmer to cut the start and end.
Is there a recording time limit?
No. Recording continues until you stop it, limited only by memory.
Why is there no sound from my computer?
System audio is only offered in Chrome and Edge, and you must tick "Share audio" in the share dialog. Tab audio works best.
Does it work on phones?
No. Mobile browsers block screen capture; use the phone's own recorder.
