AVI to MP4

Input
Higher bitrate = sharper picture, bigger file. The video is re-encoded in real time, so conversion takes as long as the clip.

What AVI to MP4 does
Turn an old AVI — a camcorder clip, a downloaded video, a screen capture — into an MP4 that plays on phones, TVs and editors. The conversion runs in your browser, so the video is never uploaded.
How to use it
- Upload an AVI file.
- Pick a video quality (bitrate).
- Click Convert to MP4, preview the result, then download it.
Good to know
Your browser plays the video and re-records it, so conversion takes about as long as the clip itself — keep the tab open. Your browser has to be able to play the file: many AVI files use codecs (DivX, Xvid, MJPEG) that browsers can't decode, in which case you'll see an error rather than a broken file. If a browser can't record MP4, it saves WebM instead and says so. Re-encoding is lossy; raise the quality for detailed footage.
Privacy
Playback and encoding happen on your device. Nothing is sent to a server.
