    About 3GP and OPUS

    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.

    OPUS: Opus is a modern, highly efficient codec used by WhatsApp voice notes, Discord, Zoom and WebRTC calls. It sounds excellent even at very low bitrates.

    Frequently asked questions

    Will converting 3GP to OPUS reduce quality?
    Only the sound is kept — the picture is dropped, so the OPUS file is far smaller than the 3GP video.
