MP4 vs AVI, in short
MP4 is the most widely supported video format: phones, browsers, editors and every upload site play it.
AVI is an old Windows video format from the 1990s. Older cameras, screen recorders and archives still produce it, but phones and most websites don't play it.
The video is re-encoded to MPEG-4 video with MP3 sound, the combination older players and editors expect. That runs on your own device, in the browser, so it takes a while for longer videos.
Frequently
Asked Questions
Does converting MP4 to AVI lose quality?
It's re-encoded once, at good quality settings. Most people won't see a difference.
Is the sound kept?
Yes. The audio track comes along with the video.
How long does it take?
It depends on the length: re-encoding in the browser uses one processor core, so expect a minute or more per minute of video.
Is my file uploaded?
No. It's processed in your browser, on your own device, and never leaves it.
