# MP4 to MOV Converter

> Convert MP4 video into a QuickTime MOV — usually without re-encoding.

MP4 and MOV are both built on the ISO base media file format, which means the video and audio inside them are usually the same streams in a different wrapper. The default here copies those streams into a MOV container without touching them — instant, and with no quality loss at all. Re-encoding is offered for files using a codec QuickTime will not play.

## FAQ

### Why is re-wrapping instant while re-encoding takes minutes?

Re-wrapping copies the compressed streams into a different container without decoding them — it is essentially a file rename with new headers. Re-encoding decodes every frame and compresses it again, which is both slow and lossy.
