M4A to MP3 Converter

M4A is Apple's audio format used in iTunes, Apple Music, and Apple devices. Technically it's AAC audio in an MPEG-4 container. The format provides good quality at compact size.

MP3 is a universal format that works on all devices. M4A may not play on older players, some car stereos, gaming consoles. MP3 is guaranteed to work everywhere.

Only with purchased tracks without DRM protection. Files from Apple Music subscription are protected and cannot be converted. Check if you can play the file outside the Apple Music app.

Yes. iPhone voice memos are saved in M4A. Export the recording via Share → Files, then upload to the converter. For speech, 128 kbps is sufficient.

M4A (AAC) is more efficient than MP3 at the same bitrate. So to preserve quality, choose MP3 bitrate 20-30% higher than the source: if M4A was 192 kbps, choose MP3 256 kbps.

M4A and MP3 are both lossy formats. Conversion involves transcoding (decoding + encoding), which adds minimal quality loss. In practice, at high bitrates this is unnoticeable.

Yes. M4A metadata (title, artist, album, cover art) is transferred to MP3 ID3 tags. All information is preserved.

M4R is M4A renamed for use as iPhone ringtone. The format is identical, only the extension differs. The converter processes both formats.

The service accepts files up to 100 MB. For a typical M4A song (4-5 minutes at 256 kbps) that's about 8-10 MB, so the limit is more than enough.

Yes. All files are processed in an isolated environment and automatically deleted immediately after conversion. We don't store, listen to, or share your files.

Yes. Open the site in Safari, upload M4A from the Files app or directly from Voice Memos via Share. The downloaded MP3 will save to Files.

M4A (AAC) is technically more efficient — better quality at smaller size. But MP3 is more universal — works absolutely everywhere. For Apple ecosystem, keep M4A; for compatibility, convert to MP3.
