AVI to MOV
Open old AVI clips on a Mac. QuickTime Player and Apple's editing apps cannot read most AVI codecs, so this tool re-encodes them into an H.264 QuickTime MOV.

How to use AVI to MOV
- Choose one or more .avi files from a camcorder, old camera or archive.
- Press Convert to MOV.
- Wait while each file is encoded; larger DV files take longer.
- Download the MOV files individually or zipped, then import them into Photos, iMovie or Final Cut.
Why Macs struggle with AVI
macOS has never shipped decoders for DivX, Xvid or many of the other codecs found in AVI files, so double-clicking one often gives an error or a black screen. The conversion decodes the AVI and writes H.264 at CRF 23 with yuv420p colour and AAC audio inside a MOV container, which every Apple app understands.
This is handy for digitising family archives, old college project videos, or clips from early digital cameras that recorded Motion JPEG AVIs. Those uncompressed or lightly compressed sources usually shrink a lot when moved to H.264.
Limitations
- Interlaced DV footage is not deinterlaced, so movement may look combed on a modern display.
- Corrupted or partially downloaded AVIs may not convert completely.
- Only one video and one audio stream are kept.
Frequently asked questions
Can I just play the AVI in VLC on my Mac instead?
Yes, VLC plays most AVIs. Converting to MOV is useful when you want the clip in Photos, iMovie, Final Cut or Keynote.
Will an MP4 work just as well?
For playback, yes. Choose MOV when your editing app or a specific workflow asks for QuickTime files.
Does the MOV keep the original resolution?
Yes. The video is re-encoded at its existing size and frame rate.
Are my AVI files uploaded?
No. Everything happens in the browser, so the files never leave your Mac.
