What Screen Recorder does
Record your screen or a tab with audio — saved locally, never uploaded.
How it works
Hybrid renderer: WebGL2 for color grading and effects, WebCodecs for decode/encode, ffmpeg.wasm for muxing and exotic codecs. Multi-threaded via SharedArrayBuffer where COOP/COEP is available. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
