A simple, full-featured screen recorder
No software to install
Everything works in Chrome, Edge, Firefox, or Safari: perfect for a work PC where you can't install anything.
Computer sound and mic
Capture the sound of a video, a meeting, or a game, and add your voice for a narrated tutorial.
No watermark or time limit
Your videos are clean, with no added logo, and the length is limited only by your computer's memory.
Private by design
The recording is created on your device: nothing is sent to our servers, nothing is stored.
Record your PC or Mac screen for free
To film a tutorial, a presentation, a bug report, or a video call, you don't need to install OBS or paid software. This online screen recorder uses your browser's built-in screen capture: you choose what to share (the whole screen, a single window, or a tab), record, then download the video. The file is MP4 when your browser supports it (Chrome, Edge, Safari), otherwise WebM, playable in VLC and most players.
Record your screen with sound
Check “Computer sound” to capture audio from a video, a video call, or music. On Windows and ChromeOS, Chrome and Edge can capture the sound of the whole system; on Mac, sound is captured when you share a browser tab. Add your mic to narrate live: both sources are mixed into the same audio track.
What about on phone?
Mobile browsers don't yet support screen recording from a web page. On iPhone, use the Control Center's screen recording; on Android, the “Screen record” quick settings tool. On computer, this tool works with no installation at all.
Frequently Asked Questions
Is the screen recorder really free?
Yes, completely free, with no sign-up, no watermark, and no limit on the number of recordings.
Are my recordings sent over the internet?
No. The video is recorded and assembled in your browser, on your device. It's never sent to Chatzam's servers.
What format is the video saved in?
MP4 when your browser supports it (recent Chrome, Edge, and Safari), otherwise WebM. Both formats play in VLC and most video players.
Why isn't my computer's sound being recorded?
When sharing, check the “Share audio” option offered by your browser. On Mac, only the sound of a browser tab can be captured; on Windows, Chrome and Edge can capture the sound of the whole system.
