How to Convert M4A to MP3 (iPhone Voice Memos)

To convert M4A to MP3, open the Audio Converter, add your M4A files, choose MP3 and a Bitrate — 128 kbit/s for voice, 192 kbit/s for music — and press Convert. Download the MP3s one by one or as a ZIP. It works for iPhone Voice Memos, iTunes purchases without copy protection, and any other M4A or AAC file.

Convert M4A to MP3 step by step

1. Get the files onto your computer (or keep them on your phone — the tool works in mobile browsers too).
2. Open the Audio Converter and add the M4A files.
3. Under Convert to, choose MP3.
4. Choose the Bitrate: 128 kbit/s for speech, 192 kbit/s for music.
5. Press Convert and download the MP3s, or Download all (ZIP).

Getting Voice Memos off an iPhone

• Share one memo: in Voice Memos, tap the memo, then ⋯ › Share, and choose Save to Files, AirDrop, Mail or a messaging app.
• On a Mac: the Voice Memos app syncs through iCloud — drag a memo out of the app onto the desktop.
• On Windows: use iCloud for Windows, or email or upload the memo from the iPhone.

Voice Memos are saved as M4A files (AAC sound in an MP4 container).

Convert on the iPhone itself

1. Save the memo to Files (Share › Save to Files).
2. Open the Audio Converter in Safari, tap the upload area, choose Browse, and pick the memo.
3. Convert, then tap the download button; the MP3 is saved to Files › Downloads.

Why convert M4A at all?

M4A plays on Apple devices and most modern apps, but trips up:

• Older Windows apps and some Android players.
• Car stereos and USB speakers that only understand MP3.
• Upload forms, transcription services and editors that ask for MP3.

MP3 works everywhere.

Improve voice recordings while you're at it

• Remove hiss and room noise with the Audio Noise Reducer — it can also even out the volume.
• Cut off the silence at the start and end, or split a long recording into parts, with the Audio Splitter.
• Make voice files smaller: tick Mono in the converter and choose 96 kbit/s — voice doesn't need stereo, and mono sounds just as clear at the lower bitrate.

M4A, AAC and M4R explained

• AAC is the sound format Apple uses — efficient and good quality.
• M4A is the usual file for AAC sound (an MP4 container with no picture).
• M4R is the same thing renamed for iPhone ringtones.

So "M4A to MP3" means re-encoding AAC sound as MP3 — which is why the bitrate choice matters.

Settings for voice memos

Voice Memos record clear mono speech. 128 kbit/s MP3 keeps them sounding exactly like the original; 96 kbit/s with Mono halves the file size again and is still perfectly clear for meetings and lectures — useful for long recordings sent by email or uploaded to transcription services.

Record straight to MP3 next time

The Voice Recorder records in your browser and downloads MP3 directly — no conversion needed.

Privacy

Recordings are converted on your device; nothing is uploaded — important for private memos, interviews and meetings.

Frequently asked questions

Will converting lose quality?

M4A and MP3 are both compressed, so converting adds a tiny loss — inaudible for voice at 128 kbit/s and for music at 192 kbit/s or above.

Can I convert protected iTunes songs?

No. Songs with copy protection (old iTunes Store purchases, Apple Music downloads) can't be converted.

Can I convert MP3 back to M4A?

Yes — choose M4A (AAC) as the output.
