Supports: AV1
AV1 is the newest open-source video codec with excellent compression, but it's not supported by older devices, legacy video editors, or hardware from before 2020. AVI is Microsoft's long-established container that works with virtually every Windows application and older media player.
Converting AV1 to AVI is useful when you need to edit AV1 footage in legacy software like older versions of Windows Movie Maker, VirtualDub, or Pinnacle Studio, or when playing video on older hardware that lacks AV1 decoding support.
| Feature | AV1 (source) | AVI (output) |
|---|---|---|
| Compression | Best available (2026) | Depends on codec |
| Legacy software support | ❌ Limited | ✅ Universal on Windows |
| File size | Very small | Larger |
| Hardware decoding | 2020+ devices | ✅ All devices |

Yes. Upload multiple files and download AVI results individually or as a ZIP archive.
