M4A to MP3 Converter

iPhones, Macs and many Android recorders save audio as M4A, which some cars, older players, websites and Windows programs will not play. Drop your M4A files here and save them as MP3, the format that plays everywhere. Choose 128 kbps for voice memos and 192 or 320 kbps for music, convert many files at once, and download them in a ZIP. It works in your browser on iPhone, Android, Windows and Mac, and your recordings are never uploaded.

How it works

M4A to MP3 Converter is a web page that does its work on your own device. The file you choose is opened by your browser, changed there and saved from there; it is never sent to a server, so there is no copy of it anywhere to delete, no queue and no waiting for an upload. Most online tools of this kind send your file to their servers and work on it there, and many keep it for a while. This one does not. There is no account, no watermark and no limit on how often you use it, and the result downloads the moment it is ready.

Converting voice memos on iPhone

In Voice Memos, open the recording's options, tap Share and choose Save to Files. Then open this page in Safari, press Choose audio files, pick the memo from Files and download the MP3, which Safari saves to Downloads in the Files app.

M4A and AAC

M4A is the file type; the sound inside is usually AAC. Files ending in .aac work here too, and both convert to MP3 the same way.

Questions

How do I convert M4A to MP3 on iPhone?

Save the recording to the Files app, open this page in Safari, press Choose audio files and pick it. Tap Download MP3 and the file is saved to Downloads in Files.

How do I convert M4A to MP3 on Windows?

Open this page in Chrome or Edge, drop the M4A files into the box and press Download MP3. Nothing needs to be installed.

Can I convert songs from Apple Music?

No. Songs downloaded from Apple Music are protected, so they cannot be opened or converted. Your own recordings and unprotected M4A files work.

Does M4A to MP3 lose quality?

Both are compressed formats, so converting adds a little loss. At 192 kbps or higher it is very hard to hear, and for voice recordings 128 kbps sounds clear.

Are my recordings uploaded?

No. The conversion happens in your browser, so private recordings stay on your device.
