MP4 to MP3 Converter

Extract audio tracks from MP4 video files on your device. No software installation or file upload is required. Your video file stays on your device throughout conversion.

.mp4, .m4v, .mov · Up to 100 MB per file

    First use may take a little longer while the conversion tool loads. Your files stay on your device. Short clips work best; processing stops after ten minutes. Unsupported codecs, protected files, or insufficient memory can prevent conversion. Bitrate applies to lossy audio outputs; WAV and FLAC use lossless encoding. Extra tracks, subtitles and metadata are not preserved.

    How to use MP4 to MP3 Converter

    1. Select or drag & drop your MP4 video file.
    2. Select your desired MP3 audio quality bitrate (128k, 192k, 256k, or 320k).
    3. Click "Convert to MP3" — the audio is extracted on your device.
    4. Download your converted MP3 file instantly.

    Frequently Asked Questions

    Clear answers regarding conversion, privacy, and technical capabilities.

    Is my video uploaded to your servers?

    Never. Your video is processed on your device. Its contents are not uploaded to a conversion server.

    What is the maximum MP4 file size supported?

    Inputs are limited to 100 MB and processing to ten minutes per job, depending on available memory. Decoded audio needs much more memory than the source file. Start with short clips; the practical limit depends on your device and available memory.

    What audio bitrate should I choose?

    192 kbps is the sweet spot for podcasts and general video audio. For music videos where high fidelity is essential, choose 320 kbps.

    Will this tool work on mobile phones?

    Conversion runs on your device. Unsupported or protected media and videos without audio cannot be converted. Mobile devices may need much smaller files.
