About TS to MP4

Convert TS, MTS, and M2TS transport-stream recordings from camcorders and tuners into MP4 so they play on devices and apps that don't support the raw stream. We re-encode to H.264 at the quality you choose.

The transcode runs entirely in your browser via WebAssembly — FFmpeg compiled to WASM — so your TS file is never uploaded to any server.
