How convert avi to mp4 works
Process
Choose an AVI file and start the conversion. Its readable video and audio tracks are re-encoded into an MP4-compatible combination.
Result
A modern MP4 with H.264 video and AAC audio that is easier to play, share, and edit.
Good to know
AVI is a container for many old codecs. Severely damaged files or codecs absent from the browser engine may not decode.
Does converting AVI reduce quality?
Re-encoding can change quality slightly, but the output uses practical settings for everyday playback.
Can an AVI without audio be converted?
Yes. A readable video track can be converted even when no audio track is present.
