Updated June 2026

AVI is a legacy Microsoft container, so converting a MOV to AVI is usually about feeding an older Windows program, editor, or player that expects the format. EchoWave does it in your browser with no desktop software to install and no signup. MOV is the modern Apple format and AVI is the old standby, so this is a compatibility move rather than a quality upgrade.

The formats

MOV vs AVI

MOV

QuickTime File Format

Apple QuickTime video, common on iPhone and Mac

Type: Video container (QuickTime)
Holds: H.264 or HEVC video with AAC audio
Typical size: Large, often bigger than MP4
Plays on: iPhone, Mac, QuickTime, most modern players

Best for:Recording and editing on Apple devices

AVI

Audio Video Interleave

A legacy Microsoft video container

Type: Legacy video container
Holds: Older codecs like DivX or Xvid with MP3 or PCM audio
Typical size: Large for the quality it gives
Plays on: Windows and VLC, patchy on phones

Best for:Playing older Windows video files

Will it lose quality?

When the codecs already match AVI, the converter can change the container without re-encoding, so the picture stays identical.
When the video has to be re-encoded for AVI, a high bitrate keeps it visually close to the MOV.
Converting cannot add detail the MOV never had. The output is at best as good as the source.

Troubleshooting

If something looks off

The AVI will not play

Some players are picky about codecs. Try it in VLC, which opens almost anything, or convert again and let the converter re-encode the video.

The file got larger

A format change can shift the size, and re-encoding at a high bitrate adds overhead. Lower the bitrate or trim the clip for a smaller file.

Audio and video drift out of sync

Re-download the source and convert again. If a long recording drifts, splitting it into shorter pieces usually fixes the sync.

FAQ

MOV to AVI questions

How do I convert a MOV to AVI?

Upload your MOV, choose AVI as the output, and start. When it finishes, download the AVI or open it in the editor to trim or resize it first.

Why would I convert MOV to AVI?

AVI is an older Microsoft container that some legacy Windows software, video editors, and hardware players still expect. If a tool refuses your MOV or only lists AVI as a supported input, converting bridges the gap without needing a desktop app.

Is AVI still worth using?

For most modern uses MP4 is the better target because it is smaller and plays almost everywhere. AVI mainly makes sense when an older program or device specifically asks for it, so pick AVI for compatibility and MP4 for general sharing.

Will converting MOV to AVI lose quality?

Converting to AVI re-encodes the video, so a high bitrate keeps the result close to the source. AVI tends to be larger than a modern MP4 at the same quality because it relies on older codecs, and the output can be at best as good as the original MOV.

Does the AVI play on Windows and VLC?

Yes. AVI opens in Windows Media Player and VLC, which is one reason people still use it. On phones it is patchy, so convert to MP4 instead if you mainly need the clip on mobile.

Is the MOV to AVI converter free?

Yes. EchoWave converts MOV to AVI with no signup, no file-count limit, no trial, and no watermark. Upload your video, convert it, and download the AVI from your browser.

Does the MOV to AVI converter work on Mac, Windows, iPhone, and Android?

Yes. The converter runs in any browser, so it works on macOS, Windows, iPhone, iPad, Android, Chromebook, and Linux with nothing to install.

The AVI will not play. What now?

Try it in VLC, which opens almost any codec. If a specific old program still rejects it, that tool may want a particular legacy codec, in which case MP4 is often the safer modern choice.
