AVI to MOV converter

Mac apps like iMovie and QuickTime struggle with DivX/Xvid AVI files from older cameras and downloads.

What happens to your AVI

MPEG-4 Part 2 or MJPEG video is re-encoded to H.264 (or ProRes Proxy) and audio to AAC inside MOV.

Tip: MJPEG camera AVIs shrink dramatically when re-encoded to H.264.

How to convert AVI to MOV

  1. Drop your AVI file on the box above, or tap it to pick one. The engine (about 31 MB) loads once per visit.
  2. The converter reads the file's streams and shows which codecs are inside.
  3. Keep the defaults, or pick a quality and resolution.
  4. Press the button, wait for the progress bar, then download your MOV.

Prefer the command line?

This is the FFmpeg command the converter runs for a typical AVI (mpeg4 + mp3). Paste it into a terminal with FFmpeg installed for batch jobs or files too big for a browser tab:

ffmpeg -y -i input.avi -map 0:v:0 -map "0:a:0?" -sn -dn -c:v copy -c:a copy -movflags +faststart output.mov

Streams are copied (-c copy), so this runs at disk speed. Your own file may contain different codecs; the converter above detects them and adapts. For other jobs, ask the FFmpeg command helper.

Questions

Will QuickTime play it afterwards?

Yes. H.264 + AAC in MOV is QuickTime's native combination.

Is my AVI file uploaded?

No. The AVI is read from your device by FFmpeg running as WebAssembly in the page, and the MOV is written back to your device. No server ever receives it.

Is there a size limit for AVI to MOV?

We set none. The practical limit is browser memory: roughly 2 GB of output on a computer, and much less on phones.
