M4A to MP3 FAQ

What is an M4A file?

M4A is an MPEG-4 audio file, usually containing AAC audio. Apple uses it for voice memos, iTunes downloads and GarageBand exports.

Will converting reduce quality?

Both AAC and MP3 are lossy formats, so converting adds a small loss. Choosing a bitrate at or above the original keeps the difference inaudible for most listeners.

Can I convert protected iTunes songs?

No. Older iTunes purchases with DRM (.m4p) cannot be converted. Songs sold since 2009 are DRM-free M4A files and convert normally.

Why is my MP3 bigger than the M4A?

AAC is more efficient than MP3, so at the same perceived quality MP3 needs a higher bitrate. Choose 128 kbps or Mono to keep files small.

What about ALAC files?

Apple Lossless files also use the .m4a extension. They convert to MP3 the same way; choose 320 kbps to keep as much quality as possible.

Why does the Voice Memos app save M4A instead of MP3?

Apple devices use AAC audio in an M4A container because it gives better quality than MP3 at the same file size and is built into every Apple product. The format is efficient but less universal, which is why converting to MP3 helps when sharing recordings outside the Apple ecosystem.

M4A, AAC and MP3

M4A is simply an MPEG-4 file containing only audio, and the audio inside is usually AAC, the successor to MP3 standardised in 1997. AAC sounds better than MP3 at the same bitrate, which is why Apple, YouTube and most streaming services use it. The downside is compatibility with older devices, car stereos and some upload forms that expect MP3.

Voice memos are the most common reason to convert. The iPhone saves them as M4A files, which play fine on Apple devices but can confuse other systems. Converting them to MP3 at 64 or 96 kbps mono keeps speech crystal clear while producing small files that any device or service accepts.

Some M4A files contain Apple Lossless (ALAC) instead of AAC. They are much larger and lossless; converting them to 320 kbps MP3 produces files that are much smaller while sounding excellent.

Because both formats are lossy, converting between them repeatedly degrades quality. Convert once from the M4A to MP3 and keep the original file if you might need the best quality later.
