Why would I convert MP4 to AVI?

AVI is supported by legacy media players, older Windows systems, and certain embedded devices that may not recognize MP4. It is also preferred in some professional video editing workflows.

Will the AVI file be larger than the original MP4?

AVI files can be larger because the container has more overhead. The actual size difference depends on the codecs used, but expect a modest increase in file size.

Does AVI support H.264 video?

Yes. AVI can contain H.264 video streams, though some older AVI players may only support classic codecs like DivX or Xvid.

Can I play AVI files on Mac?

Yes, with VLC or similar cross-platform players. macOS does not natively support AVI in QuickTime, but third-party players handle it without issues.

Is the conversion process private?

Absolutely. All conversion happens directly in your browser. Your video files never leave your device or get uploaded to any server.
