What Is Screen Recorder?

The Screen Recorder is a free browser-based tool that captures your screen activity as a video file. Record your entire screen, a specific application window, or a browser tab — with or without audio. It uses the browser's getDisplayMedia API for screen capture, providing smooth, high-quality recordings. It's perfect for creating tutorials, bug reports, presentations, and demonstrations. No software installation is needed — everything runs directly in your browser. The recording is saved locally and never uploaded to any server, ensuring complete privacy.

Why Use Screen Recorder?

Record screen, window, or browser tab with one click
Optional audio capture (system audio and/or microphone)
No software installation — works in any modern browser
Recordings stay on your device — fully private

Technical Guide

The Screen Recorder uses the navigator.mediaDevices.getDisplayMedia() API to capture screen content. This API prompts the user to select a screen, window, or tab to share. Options include video resolution constraints, frame rate (typically 30fps), and system audio capture via audio: true. For microphone audio, getUserMedia() is called separately and the streams are merged using Web Audio API. The combined MediaStream is fed to a MediaRecorder configured for video/webm encoding. Recording controls (start, pause, resume, stop) map to MediaRecorder methods. The recorded data is collected via the ondataavailable event and assembled into a downloadable Blob. A timer displays the recording duration in real-time.

Tips & Best Practices

2
Use "Tab" capture for sharing a single browser tab with audio
3
System audio capture requires checking the "Share audio" option in the browser prompt
4
Recording quality depends on your screen resolution and system performance

Frequently Asked Questions

Q Can I record with audio?

Yes! System audio (from the captured tab/screen) and microphone audio can both be captured. Check "Share audio" in the browser prompt.

Q What format is the recording?

Recordings are saved as WebM video files, which are supported by all modern browsers and media players.

Q Are screen recordings uploaded to a server?

No. Recordings are saved locally and never uploaded to any server. Screen sharing permissions are controlled by your browser.

Q Can I record a specific window?

Yes, the browser prompt lets you choose to record your entire screen, a specific window, or a single browser tab.

Q Is there a recording time limit?

No built-in time limit, but very long recordings produce large files. Your device's available memory is the practical limit.
