How to use this tool

To convert M4A to MP3, choose the M4A file, pick 128, 192 or 320 kbps and press Create file. M4A is the audio format of iPhone Voice Memos, iTunes and many recorder apps; MP3 is the format every car stereo, older player, website and editing tool accepts. The recording is converted in your browser and stays on your device, and the MP3 keeps your file name and title tag.

  1. 01

    Choose your M4A file

    Click Choose files and select an M4A recording or song up to 100 MB and 10 minutes.

  2. 02

    Pick the MP3 bitrate

    128 kbps is plenty for voice memos and lectures. Use 192 kbps for music, or 320 kbps for the best quality.

  3. 03

    Convert and download

    Press Create file, listen to the MP3 and click Download.

Getting a voice memo off your iPhone

In the Voice Memos app, tap the recording, tap the three dots (or the Share button) and choose Save to Files. Then open this page in Safari, tap Choose files and pick the memo from Files. On a Mac, drag the memo from the Voice Memos app to the desktop and choose it here.

M4A vs MP3

M4A usually holds AAC audio, which sounds slightly better than MP3 at the same bitrate. MP3 is older and supported by nearly every device, website and app, including car stereos, DJ software and podcast hosts. Convert when a device, editor or upload form asks for MP3; voice memos, recorder files and unprotected iTunes songs all convert directly.

Which bitrate to pick

• 128 kbps: voice memos, meetings, lectures; about 1 MB per minute • 192 kbps: music and mixed content; about 1.4 MB per minute • 320 kbps: highest MP3 quality; about 2.4 MB per minute For a recording made at 64 kbps, like the example memo, 128 kbps keeps everything in it at a compact size.
