How do I convert an MP4 video to an M4A audio file?

Upload your MP4 file, select M4A as the output format, and click 'Convert'. The tool extracts the audio stream (usually AAC) and saves it as an M4A file. Once finished, download the M4A file directly.

Why would I convert MP4 to M4A instead of keeping the MP4?

M4A is an audio-only container, so converting MP4 to M4A strips the video track and significantly reduces file size while preserving audio quality. M4A is natively supported by Apple devices, iTunes, and most Android players, making it ideal for music libraries and podcasts.

Does converting MP4 to M4A preserve the original audio bitrate and sample rate?

Yes. Our converter performs a lossless container remux when the source is AAC: the audio stream is copied without re-encoding, preserving bitrate, sample rate, channel count, and metadata. If you choose to re-encode, you can manually adjust these parameters.

Is MP4-TO-M4A free to use?

Yes, MP4-TO-M4A on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! MP4-TO-M4A works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
