Screen Recorder captures your screen directly in the browser — no download, no install, no watermark, no time limit imposed by us. It uses the browser's built-in Screen Capture API (getDisplayMedia) to record your entire screen, a single application window, or one browser tab, with optional microphone narration. When you stop, the recording downloads as a WebM video file. Because recording happens locally on your machine, nothing is ever uploaded — your screen content stays completely private. Ideal for tutorials, bug reports, demos, and quick how-to clips. Works on Chrome and Edge on desktop.
The tool calls the browser's Screen Capture API (navigator.mediaDevices.getDisplayMedia), which shows the browser's own picker asking what to share — entire screen, a window, or a tab. The video stream (optionally mixed with your microphone via getUserMedia) is encoded in real time by the MediaRecorder API into WebM (VP8/VP9). Frames are held only in your browser's memory and written straight to the downloaded file — no server is involved at any point.
| Capture scope | Best for | Watch out for |
|---|---|---|
| Entire screen | Multi-app workflows, presentations | Notifications and other windows are visible |
| Application window | Software tutorials, bug reports | Popups from other apps are not captured |
| Browser tab | Web-app demos, walkthroughs | Cleanest option — only that tab is recorded |
Tab capture also lets Chrome share the tab’s own audio; screen and window capture record mic audio only.
Close notification popups (turn on Do Not Disturb / Focus mode) before you start — a WhatsApp banner in a client demo is the classic mistake. Record a tab rather than the whole screen when possible: it hides your bookmarks, other tabs, and desktop. Keep recordings short and single-topic; three 2-minute clips beat one 10-minute ramble. If you're narrating, do a 5-second test first to confirm the mic level, and pause a beat between sentences — it makes trimming easier later.
Browsers' MediaRecorder API produces WebM (VP8/VP9 video), an open format that plays in Chrome, Edge, Firefox, VLC, and uploads fine to YouTube, Google Drive, and Slack. Some tools — notably older video editors, iPhones, and WhatsApp — prefer MP4. If you need MP4, convert the downloaded WebM with a converter such as VLC (Media → Convert/Save) or HandBrake, both free. For most sharing (YouTube, Drive links, bug trackers), WebM works as-is with no conversion.
Desktop recorders like OBS are powerful but overkill for a quick capture — they need installation, configuration, and often admin rights you may not have on an office machine. A browser recorder needs none of that: open the page, pick what to share, record, download. Because Clacify's recorder runs entirely client-side, it's also safe on confidential material — the video is encoded on your machine and never uploaded, unlike "free online recorder" sites that process video on their servers. The trade-off: it needs Chrome or Edge on desktop, and advanced features like webcam overlay or live streaming still belong to OBS.
Open Clacify's Screen Recorder in Chrome or Edge. Click Start Recording — your browser will ask you to select the screen, window, or tab to record. Optionally enable microphone audio for narration. Click Stop when done, and the recording downloads as a WebM file automatically.
Yes. Clacify's Screen Recorder can record: (1) Microphone audio (your voice narration) — toggle the mic option before starting. (2) System audio (computer sounds) — available on some browsers and platforms when you select 'Share tab audio' in the share dialog. The WebM output includes all selected audio tracks.
