## What this tool does
Convert MKV, WebM, FLV or TS to MP4 without re-encoding — instant, zero quality loss.

## Typical user problems
- Players, editors and chat apps refuse everything that is not MP4. Remuxing copies the existing audio and video streams into an MP4 container as-is — a seconds-long operation with bit-identical quality. If the source codec cannot live inside MP4 (e.g. VP8), it falls back to one clean H.264 re-encode automatically.
