How do I extract audio from an MP4 video?

Upload your MP4 file, click 'Start Processing', and the tool automatically extracts the audio and saves it as M4A. The process runs in your browser - no uploads needed.

M4A (MPEG-4 Audio) is an audio container format that typically uses AAC encoding. It offers better sound quality than MP3 at the same file size and is natively supported on Apple devices.

Is the conversion secure?

Yes. All processing happens in your browser via FFmpeg WebAssembly. Your files never leave your device.

M4A vs MP3 - which should I choose?

Choose M4A if you primarily use Apple devices (iPhone, iPad, Mac) or want better audio quality at smaller file sizes. Choose MP3 for maximum compatibility with all devices including older hardware.

Can I convert multiple files at once?

Yes. Our converter supports batch processing - upload up to 10 MP4 files at once.
