Built With Care

“Recording relies on getDisplayMedia for the screen stream and the MediaRecorder API for encoding, with automatic fallback from the VP9 codec to VP8 or H.264 depending on browser support. When both microphone and system audio are selected, the two tracks are mixed through a Web Audio API AudioContext node before encoding.”

Free Online Screen Recorder

A free online screen recorder for capturing your full screen, a specific window, or a browser tab with optional microphone or system audio. Recording uses the browser MediaRecorder API and saves a WebM file locally — no uploads, no software installation required.

Important Notes
  • Granting screen and audio permissions is required; if you deny the prompt, recording cannot start.
  • Recorded chunks stay in browser memory until you download, so very long sessions can slow down the page.
  • Streaming services with DRM protection may render as a black frame during capture.
Quick Checklist
  • 1Confirm the chosen audio source matches what you plan to say or play.
  • 2Play back the preview once before distributing the file.
  • 3Download the recording promptly to free browser memory for the next session.
