What the converted AVI contains
The AVI output uses MPEG-4 Part 2 video and MP3 audio. This differs from the H.264/AAC combination used by the MP4, MOV, and MKV outputs.

Video to AVI converter
AVI output helps with older players, archives, and tools that still expect an AVI video file.
- Convert MP4, MOV, WebM, MKV, MPEG, and other video files to AVI.
- Create AVI videos for older players, archives, and compatibility-focused workflows.
- Download the converted AVI directly after the online conversion finishes.
When AVI still helps
AVI can be useful for older Windows-era software, legacy playback devices, and workflows that explicitly require an .avi container. For a new web or mobile workflow, MP4 is usually a better first choice.
AVI file-size tradeoffs
AVI is an older container and the MPEG-4 video output may be less storage-efficient than a modern H.264 MP4. Converting does not guarantee a smaller file, even when the extension changes.
Compatibility limits
AVI can contain many codecs, so software that accepts one AVI file may reject another. Check that the destination supports MPEG-4 Part 2 video and MP3 audio.
