    About AVI and M4A

    AVI is Microsoft’s classic video container, still common in older recordings. M4A is Apple’s AAC-based format, standard for iTunes, iPhone recordings and Apple Music downloads. Converting from AVI to M4A is one of the most common format jobs — and with this tool it takes seconds, with no software to install.

    Why convert AVI to M4A?

    • Compatibility — your player, phone or app accepts M4A but not AVI.
    • Sharing — send M4A files that open everywhere without special software.
    • Editing — many editors and DAWs prefer M4A as their working format.
    • Archiving — keep a copy in M4A so the audio stays playable for years.

    Frequently asked questions

    Is this AVI to M4A converter really free? Yes — completely free, with no sign-up, no credit card, and no limits on how many files you convert.

    Are my files uploaded to a server? No. The conversion runs 100% in your browser using your own device, so your files never leave your computer or phone. That makes it faster and completely private.

    Will the quality change? M4A is a lossy format, so a small amount of audio data is discarded — at 192 kbps or above, almost nobody can hear the difference. Use 320 kbps if the M4A files are for serious listening.

    Can I convert several AVI files at once? Yes — add a whole batch and convert them all with one click. Each converted file gets its own download button.
