About This Tool

M4A is Apple's preferred audio container format, used throughout the Apple ecosystem. iTunes purchases, Apple Music downloads, iPhone Voice Memos, and GarageBand exports all use the M4A format. While M4A provides excellent audio quality, it's not universally supported outside the Apple ecosystem. Many Windows applications, Android devices, older media players, and car audio systems can't play M4A files. Converting M4A to MP3 gives you a universally compatible audio file that works on every device and platform. All processing happens directly in your browser using WebAssembly technology for complete privacy.

Frequently Asked Questions

What is the M4A audio format?
M4A is an audio file format based on the MPEG-4 container. It's Apple's standard audio format used for iTunes purchases, Apple Music, iPhone Voice Memos, and GarageBand exports. M4A files typically use AAC or ALAC codec for audio encoding.
How do I convert iPhone Voice Memos to MP3?
iPhone Voice Memos are saved as M4A files. Share the recording from the Voice Memos app to your computer (via AirDrop, email, or Files), then upload the .m4a file here to convert it to MP3.
Can I convert iTunes music to MP3?
Yes, if you have DRM-free M4A files from iTunes purchases (purchased after 2009), you can convert them to MP3 here. Note that DRM-protected files cannot be converted with any third-party tool.
Will I lose quality converting M4A to MP3?
Converting between lossy formats does involve some quality loss, but at 320kbps the difference is negligible for most listeners. For archival purposes, keep your original M4A files as backups.
What's the difference between M4A and MP3?
M4A uses the AAC codec which is technically more efficient than MP3 — it produces better quality at the same bitrate. However, MP3 has universal compatibility across all devices, platforms, and media players, making it the safer choice for sharing.
