Lossless WebM to MP4 Converter
Stop re-encoding WebM — convert AV1 to MP4 instantly

I built this because most WebM → MP4 tools still re-encode unnecessarily.
That adds delay and can reduce quality for no reason.
This tool skips that completely — it just remuxes via FFmpeg stream copy.
Result:
• no quality loss
• instant conversion
• minimal CPU usage
Built it for my own workflow — sharing it here.
