About MP4 to AVI
Some older programs, media players and Windows tools still expect AVI rather than modern MP4. MP4 to AVI converts your video into the classic AVI container so it opens cleanly in software that has not kept up with newer formats.
Upload your MP4 and download the AVI version in moments. The whole process happens in your browser, with no account, no watermark and nothing to install. Codaiman keeps the tool free and privacy-first, so you can feed a legacy editor or player exactly the format it needs without installing a desktop converter or signing up anywhere.

FAQ
Why would I choose AVI over MP4?
AVI is an older format mainly useful for compatibility with legacy software and devices. For everyday use, MP4 is smaller and more widely supported.
Are AVI files larger than MP4?
Often yes. AVI tends to use less efficient compression, so the same video can take up more space than its MP4 version.
Will the conversion keep my video's resolution?
Yes. The output AVI keeps the original resolution and frame rate of your MP4.
Can I use MP4 to AVI on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
