Free Online Screen Recorder — Record Your Screen in the Browser

Q: What format is the recording saved in?

Recordings are saved as MP4 (H.264 video, AAC audio). The browser captures in WebM internally, then FFmpeg.wasm converts it to MP4 locally — nothing is uploaded.

Capture your full screen, a specific window, or a browser tab. No installation, no sign-up, no upload — everything stays in your browser.

What You Can Record

Entire Screen

Capture everything visible on your display — perfect for tutorials that span multiple apps.

Application Window

Record a single window while keeping your desktop and other apps private.

Browser Tab

Capture a single Chrome or Edge tab — includes tab audio when enabled.

How It Works

Click Start Recording

Your browser will ask you to choose what to share — your entire screen, a specific window, or a browser tab.

Record with controls

Pause and resume anytime. A live timer tracks the recording length so you stay on pace.

Preview your recording

Once you stop, the video plays back directly in the browser so you can review it before saving.

Download as MP4

The recording converts to MP4 in your browser using FFmpeg — no upload needed. Save the file directly to your device.

Browser Screen Recording vs. Desktop Apps

Browser-based screen recording uses the Screen Capture API built into modern browsers. It's fast to start, requires no installation, and works on any operating system — Windows, macOS, Linux, and ChromeOS.

The trade-off is features. Browser recording captures raw video without post-processing. You won't get auto-zoom, annotations, webcam overlays, or a built-in editor. For quick captures — bug reports, sharing a workflow, or recording a meeting — the browser is perfect.

For professional screen recordings with smart auto-zoom, built-in editing, 4K export, and system audio, a native app like Screen Charm gives you a polished result without the manual work.

Frequently Asked Questions

Is this screen recorder really free?

Yes, completely free with no limits on recording length or number of recordings. The tool runs entirely in your browser using the Screen Capture API — no server processing, no account needed, no watermarks.

Is my recording private?

Yes. Nothing is uploaded to any server. The recording is created locally in your browser and saved directly to your device when you click download. We never see or store your content.

Which browsers support screen recording?

Chrome, Edge, and Firefox support the Screen Capture API on desktop. Safari has limited support (macOS 13+). Mobile browsers generally do not support screen capture. For the best experience, use Chrome or Edge.

Can I record audio with my screen?

Tab audio works in Chrome and Edge when you record a browser tab and check "Share tab audio." System audio and microphone recording are not supported by browser APIs. For full audio capture, you'll need a native app like Screen Charm.

What format is the recording saved in?

Recordings are saved as MP4 (H.264 + AAC). The browser captures in WebM internally, then FFmpeg.wasm converts it to MP4 locally — no upload involved. MP4 plays on every device and platform.

Is there a time limit on recordings?

No hard limit — you can record for as long as your browser has memory available. Very long recordings (1+ hours) may produce large files. As a guideline, expect roughly 20–40 MB per minute at standard quality.
