What this tool is for

It is for modern WebM files that should become MP4 without quality loss on the paid path. Some legacy codecs require re-encoding and are outside the scope of this tool.

Remux, not re-encode

Compatible streams are copied directly on the paid path. That keeps the original quality and skips the heavy part.

Batch-ready

Drop one file or a whole folder. The workflow stays the same and the original files are untouched.

Offline and simple

No browser upload, no account, no subscription. Just a local Windows utility.
