What is M4V to AVI conversion?

MPEG-4 Video (M4V) and Audio Video Interleave (AVI) are two popular video containers, but not every player or editor handles them all. This free converter reads your .m4v file, decodes its streams and re-encodes them into a valid .avi file with widely supported codecs. The whole conversion runs in your browser, so your video stays private.

How it works

1Upload a .m4v video file.
2Choose AVI from the output format menu.
3Click Download — the video is re-encoded locally in your browser.
4Save the converted .avi file. No signup needed.
