Frequently Asked Questions

Why can't I record system audio?

System audio capture requires selecting "Share audio" during screen selection. This option appears when choosing what to share. Safari doesn't support system audio capture.

What format are recordings saved in?

Recordings save as WebM files with VP9 video codec. Most video players and editors support this format. Use VLC or convert to MP4 if needed.

Is there a recording time limit?

No time limit from our tool. Recording duration is limited only by your browser memory and storage space.

Can I record multiple monitors?

Yes! When prompted, you can select any connected monitor to record.

Why is my recording laggy?

High-resolution screens with complex content may strain resources. Try:

• Recording a specific window instead of full screen
• Closing resource-heavy applications
• Using a browser tab instead of full screen

How do I record with a webcam overlay?

Webcam picture-in-picture is coming soon. Currently, record screen and webcam separately and combine in video editing software.

Is my recording private?

Yes. Everything processes locally in your browser. No data uploads, no server involvement, complete privacy.

This tool is for capture only. Edit downloaded files in video editing software like DaVinci Resolve, iMovie, or Shotcut.
