How does the screen recorder work?

The screen recorder uses your browser's built-in getDisplayMedia and MediaRecorder APIs. When you click Start Recording, your browser asks you to select a screen, window, or tab to share. The video stream is recorded locally in your browser — no data is ever sent to a server.

What file format is the recording saved in?

Recordings are saved as WebM files, which is the standard format supported by browser-based recording. WebM is widely compatible and can be played in most modern browsers and media players like VLC.

Can I record audio with my screen recording?

Yes! Check the Include Microphone Audio option before starting your recording. Your browser will ask for microphone permission. The microphone audio will be mixed into the final recording.

Is there a time limit on recordings?

There is no time limit imposed by Tools Oasis. However, very long recordings may use a significant amount of memory in your browser. For best results, keep recordings under 30-60 minutes.

Is my recording private and secure?

Absolutely. Your recording never leaves your device. Everything — the screen capture, the encoding, and the file creation — happens entirely inside your browser. Tools Oasis has no server-side processing and cannot access your recording.
