How to record your screen
- Choose what goes into the video: your microphone, the sound of the tab or screen you share, and an optional webcam bubble in a corner.
- Press Start recording. Your browser opens its own sharing window: pick a whole screen, one window or a browser tab. To include the sound, turn on Share audio there as well.
- After the countdown, do what you want to show. The timer and the file size so far are on this page; Pause skips a part you don't want.
- Press Stop recording, or Stop sharing in the browser's bar. Watch the result, cut the start and end if you like, and download it as MP4 or WebM.
Private, free and without a watermark
The recording is made by your browser's built-in recorder and saved second by second in this browser's own storage on your computer. Nothing is uploaded: there's no account, no server copy, no watermark and no time limit apart from your free disk space. Because each second is saved as it's recorded, a long recording doesn't fill your memory, and if the tab crashes or you close it by mistake, the next visit offers the part that was saved. One recording is kept at a time: starting a new one, or pressing Delete recording, removes it.
MP4 or WebM?
An MP4 with H.264 video and AAC sound plays on every phone, Mac and Windows PC and uploads anywhere. WebM files are often smaller and play in browsers, on YouTube and in VLC, but not in every editor. Recent versions of Chrome, Edge and Safari record MP4 directly; Firefox records WebM. If you download the other format, the tool converts the video on your device, which takes a while for long recordings. Some browsers, such as Chromium on Linux, can make MP4 video but not AAC sound: the MP4 then keeps Opus sound, which QuickTime and iPhone Photos can't play, and the page says so before you download. Trimming in the format you recorded copies the video without re-encoding, so it's quick, and the cut may start up to a second early, on the nearest key frame.
Recording sound
The microphone is mixed with the sound you share into one track. What can be shared depends on the browser: Chrome and Edge record a tab's sound, and the whole computer's sound when you share an entire screen on Windows or ChromeOS. Firefox and Safari record the screen without its sound, so only the microphone is heard (browser support as of October 2026). If the browser can't share a sound, the recording simply has none. Wear headphones if you talk over a video, or your microphone picks the sound up a second time. To check your microphone first, use the mic test; for the camera, the webcam test.
The webcam bubble
With the bubble on, your camera is drawn into a corner of the video as a circle or rounded square, in one of three sizes. It is part of the recorded picture, so it shows in any player. In Chrome and Edge it keeps moving while you work in another window; in Firefox and Safari keep this tab visible, for example on a second screen, or the bubble may freeze.
Tips for a good screen recording
- Share a single window or tab instead of the whole screen to keep notifications and other windows out of the video.
- Pick 1440p for sharp code and small text, 60 fps for games and fast scrolling, and 720p when the file has to stay small. A screen with little movement makes much smaller files than the estimate.
- For a recording to send by email or chat, make the file smaller with the video compressor, or take only the sound with extract audio.
- On a phone, use its built-in screen recorder: Control Center on iPhone and iPad, Quick Settings on Android.
