    3GP vs M4A

    Only the sound is kept — the picture is dropped, so the M4A file is far smaller than the 3GP video. Phone videos usually carry AAC audio, so in Smart mode the M4A is extracted instantly with zero quality loss.

    About 3GP and M4A

    3GP: 3GP was designed for mobile phones in the 2000s. It keeps files tiny, which makes it perfect for old keypad phones, feature phones and very slow connections.

    M4A: M4A is an MPEG-4 container holding AAC audio. It sounds better than MP3 at the same size and is the default format for iPhone voice memos, Apple Music downloads and many Android recorders.

    Frequently asked questions

    How do I convert 3GP to M4A on my phone?
    Open this page in your phone's browser (Safari, Chrome, Samsung Internet), tap Choose files, pick your 3GP, make sure M4A is selected and tap Convert. The M4A file is saved to your Downloads.
    Will converting 3GP to M4A reduce quality?
    Only the sound is kept — the picture is dropped, so the M4A file is far smaller than the 3GP video. Phone videos usually carry AAC audio, so in Smart mode the M4A is extracted instantly with zero quality loss.
    Can I convert only part of the 3GP?
    Yes. Open Advanced options → Trim and enter a start and end time.
    Is this 3GP to M4A converter free?
    Yes — completely free with no limits on the number of files, no watermark and no account. The site is supported by ads.
    Are my files uploaded to a server?
    No. The converter runs inside your browser using WebAssembly, so your files never leave your device. That's also why it works for private and confidential recordings.
