Record your screen, a window or a tab with your voice, and save it as MP4 or WebM
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.A browser screen recorder captures a screen, one window or one tab and saves it as a video file with no watermark and no upload. Chrome and Edge from version 126 and Safari save MP4; Firefox saves WebM. Phones cannot share the screen with a web page.
Tick Record my microphone if you want to talk over the recording.
Press Start recording and choose a screen, window or tab in the browser sharing window.
Use Pause and Resume as needed, then press Stop and preview.
Play the preview and press Save to download the MP4 or WebM file; nothing is uploaded.
This page records whatever you choose in the browser's own sharing window, the whole screen, one application window or one browser tab, and turns it into a video file you can save. The recording is made and kept inside this page. Nothing is uploaded, there is no account, and there is no watermark.
Two sources can go into the recording. Your microphone is added when you tick the box and allow it. The sound of what you share is added when you tick Share audio in the browser's sharing window; Chrome and Edge offer it for a tab and, on some systems, for the whole screen, while Firefox and Safari do not offer it at all. When both are present they are mixed into one track, because a video file made this way keeps only one. The page says what sound it actually got, so a silent recording is never a surprise.
The page asks the browser which formats it can write and picks MP4 when it can, because MP4 plays on nearly every phone, editor and messaging app. Chrome and Edge write MP4 from version 126 and Safari writes it too. Firefox writes WebM, which plays in browsers, VLC and most editors but not in some phone galleries. The chosen format is shown before you start. WebM files from a browser often carry no length, so a player may not show a seek bar until it has played through once.
Pause and resume as often as you like; the timer stops while paused. Stop here, or press Stop sharing in the browser's bar, and the recording appears in a player so you can check it before saving. The recording lives in memory until you save or discard it, so closing the tab first loses it, and a very long recording uses memory in proportion to its length.
Safari on iPhone and Chrome on Android do not let websites share the screen, so no web page can record there. The page says so and points to the phone's built-in recorder in Control Centre or Quick Settings.
No. The browser hands the shared screen to this page, the page turns it into a video file in memory, and the file only leaves the page when you press save. No server receives any part of it, which is also why there is no watermark and no length limit set by us.
Tick the microphone box to add your voice. To add the sound of what you share, tick Share audio in the browser's sharing window, which Chrome and Edge offer for a tab. When both are on, the page mixes them into one track, and it tells you what sound the recording actually contains.
The page asks the browser which formats it can write and uses MP4 whenever the answer is yes. Chrome and Edge can from version 126 and Safari can too. Firefox writes only WebM, and an older Chrome does the same, so updating the browser or switching to one of those gives MP4.
No. Safari on iPhone and Chrome on Android do not let any website share the screen, so a web page cannot record it. Both phones have a recorder built in: Screen Recording in the iPhone Control Centre, and Screen record in the Android Quick Settings from Android 11 onwards.
No fixed limit is set, but the whole recording is held in the browser's memory until you save it, so its size grows with its length. The page shows the size while recording. For long sessions, stop and save every so often rather than recording for hours in one go.
Recording stops when the shared screen, window or tab goes away: pressing Stop sharing in the browser's bar, closing the shared window, or closing the shared tab all end it. Whatever was recorded up to that moment is kept and appears in the preview, ready to save.
