How to convert iPhone voice memos to MP3

The Voice Memos app records in M4A, which contains AAC audio. Apple devices and modern browsers play it happily. Problems start with older car stereos, some Windows applications, transcription services with strict upload rules, and podcast or LMS platforms that only accept MP3.

Getting the memo off the phone

1. In Voice Memos, tap the recording, tap the three dots and choose Share.
2. AirDrop it to your Mac, save it to Files, or email it to yourself. Any route ends with an M4A file on a computer.
3. Open the M4A to MP3 converter, drop the file in and convert. A one hour recording takes moments because the audio is processed locally.

Quality considerations for speech

Voice memos are mono speech, which compresses beautifully. The converter's MP3 setting is more than transparent for spoken word. Converting between two lossy formats does lose a little information each time, so convert once and keep both files rather than bouncing back and forth.

For interviews and important recordings

• Keep the original M4A as your archive copy. Storage is cheap, re-recording an interview is impossible.
• If you plan to edit the audio, convert to WAV instead. Editors prefer it and you avoid a second lossy step when exporting.
• Batch works: drop ten memos at once and download them all as a single ZIP.

Recordings of meetings, patients or clients are exactly the kind of file that should not be uploaded to a random converter server. Here they never leave your machine.
