Screen Recorder
Record your screen, window, or tab — with optional mic narration, never uploaded.
Updated July 7, 2026
How to use the screen recorder
- 1Choose whether to include microphone narration.
- 2Click start and pick a tab, window, or your entire screen in the browser's picker (check 'share audio' for tab sound).
- 3Record — the timer runs, and ending the share from the browser bar also stops cleanly.
- 4Preview the clip, then download the .webm. Nothing is kept after the tab closes.
Common uses
- Recording a quick bug reproduction or how-to for a teammate
- Capturing gameplay clips or app demos without OBS setup
- Making tutorial footage to edit in CapCut for short-form content
- Recording a walkthrough with voice narration for a client or class
Frequently asked questions
Is the recording uploaded anywhere?
No — capture, preview, and download all happen locally using the browser's MediaRecorder API. The video exists only in this tab's memory until you download it, and closing the tab discards anything unsaved. That's the entire privacy model.
Can it record audio?
Two sources: tab/system audio (check 'share audio' in the browser's picker — full support in Chrome and Edge, mainly for tab capture) and your microphone via the narration checkbox. Enable both and they're mixed into one track.
What format is the video, and can I edit it?
WebM with VP9 video — plays in every modern browser and player, and imports into CapCut, Premiere, DaVinci, and YouTube directly. If a specific workflow demands MP4, any converter handles WebM → MP4 losslessly enough.
Is there a recording length limit?
No artificial one. Recordings buffer in memory at roughly 5–15 MB per minute depending on content, so multi-hour captures are possible on any modern machine — though for very long sessions, stopping and downloading in chapters is safer.
About this tool
The screen recorder captures your screen, a single window, or one browser tab — your choice in the browser's own picker — with optional microphone narration mixed in, and hands you a downloadable video the moment you stop. Everything the competition charges for or gates is simply absent: no watermark, no time limit, no account, no upload. Recording happens with the browser's native capture APIs, the video exists only in your tab's memory, and the .webm download plays everywhere modern and drops straight into CapCut or any editor. Tab-audio capture works in Chrome and Edge for recording videos or calls with sound; the mic option layers your voice over everything.
Like everything on UtilityBase, the screen recorder runs entirely in your browser — nothing you enter is uploaded or stored on a server. It's free to use with no account required. Browse more productivity tools here.
