# Screen Recorder

> Record your screen, windows, or browser tabs. No download required.

- Open in browser: https://pockettoolbox.org/en/screen-recorder
- Runs entirely in your browser; files and input are never uploaded.

## How it works

Create video recordings of your screen directly in the browser, without installing additional software.

After clicking "Start Recording", choose the source (screen, window, or tab). The tool generates a WebM video that can be checked in the preview and downloaded immediately.

Uses navigator.mediaDevices.getDisplayMedia({ video: true, audio: true }) for screen capture as a MediaStream. Recording is processed via the MediaRecorder API (MIME type "video/webm;codecs=vp9,opus" or vp8). Blobs are collected on dataavailable events and aggregated into a cohesive Blob/File upon stopping.
