Is this M4A to MP3 converter free?

Yes. It’s free, with no account and no limit on the number of files.

Are my files uploaded anywhere?

No. The conversion runs in your browser on your own device; your M4A files and the MP3s stay with you.

Which is better, M4A or MP3?

At the same bitrate, AAC in an M4A usually sounds a little better. MP3 plays on more devices, from car stereos to old players. Convert when a device or site asks for MP3.

Can I convert iPhone voice memos?

Yes. Voice memos are mono M4A files. Choose them from the Files app; the MP3 stays mono and 128 kbps is enough.

Are the album cover and song details kept?

Yes. Title, artist, album, track and disc numbers, genre, year and cover art are written into the MP3.

Why won’t an M4P file convert?

M4P files are iTunes songs with copy protection from before 2009. They only play in Apple’s apps, so they can’t be converted.

Can I convert songs downloaded from Apple Music?

Only songs you bought. Downloads made with an Apple Music subscription are protected and play only in Apple’s apps.

Does it work with M4B audiobooks?

Yes, if the audiobook isn’t protected. It becomes one long MP3; chapter marks aren’t carried over.

Can I convert a whole album at once?

Yes. Add every track together; they convert one after another and each downloads as its own MP3.

Is converting M4A to MP3 legal?

Converting files you recorded or have the rights to is fine. Copying other people’s work is governed by copyright law: in the US, the owner holds the right to make copies (17 U.S.C. § 106) and fair use (§ 107) is decided case by case. This converter works only on files on your device and downloads nothing from other sites.

How do you convert M4A to MP3?

To convert M4A to MP3 in your browser, open the converter, add your M4A files and choose a bitrate: 128 kbps for voice memos and meetings, 320 kbps for songs. Each file is decoded and saved as an MP3 on your own device, with its title, artist, album and cover art written into the new file. There is nothing to install and no account to make.

Convert M4A to MP3 in three steps

From a single voice memo to a full album, the steps stay the same.

Add the M4A files
Drop in one recording or a whole album. Every file shows what is inside: AAC or lossless ALAC, sample rate, mono or stereo, and length.
Pick the MP3 bitrate
The converter suggests one from the file itself: 320 kbps for lossless and store-bought songs, 128 kbps for mono voice recordings. The expected size sits next to each choice.
Save the MP3s
Play each result, then download it under its original name with the song details and artwork already inside. Send a recording on to the transcriber in one click.

Why use this M4A to MP3 converter

Made for the files people actually have: songs from an Apple library, phone recordings and meeting audio.

Title, artist, album and cover art come along

Songs bought from iTunes carry their details and artwork. Here they are written into the MP3 in a tag format that Windows File Explorer, car stereos and older players read, so a converted album still shows its covers and track order.

The right bitrate for each file

A lossless ALAC track or a 256 kbps purchase deserves 320 kbps. A mono voice memo sounds the same at 128 kbps and stays mono, so the MP3 is small. The converter reads the file and suggests the fitting choice.

Your recordings stay with you

Voice memos and meetings are often private. Decoding and encoding happen in your own browser, so a recording of a doctor’s visit or a team call stays on your device the whole time.

AAC and lossless ALAC both open

Most M4A files hold AAC sound; music libraries ripped in lossless use ALAC. Both are read, and so are M4B audiobooks and M4R ringtones, which are M4A files under another name.

No silence added, nothing cut

Each MP3 carries the information players use to skip the encoder’s padding, so tracks from a live album or a continuous mix flow into one another the way they did before.

From a meeting recording to a transcript

A converted meeting or interview can go straight to the transcriber, and a song to the vocal remover, without downloading it and choosing it again.

M4A to MP3 samples

Each sample is an M4A made from this site’s own recordings and converted here. Compare the spectrum and the size before and after.

Your songs and recordings stay yours

What the converter does with your files, point by point.

M4A to MP3 guide: sources, bitrates and other ways

What an M4A file is

M4A is an MP4 file that holds only sound. Inside is usually AAC, the format Apple uses for music, voice memos and podcasts; music ripped without loss uses ALAC instead. M4B is the same container used for audiobooks, and M4R for iPhone ringtones.

M4A plays well on Apple devices and in most modern apps, but car stereos, older MP3 players, some editing tools and many websites still expect MP3. That is the usual reason to convert.

Where your M4A files come from

The source tells you which bitrate to pick and what to expect from the MP3.

1iPhone voice memos: mono AAC speech. Choose 128 kbps; the MP3 stays mono and small.
2Songs bought from the iTunes Store: 256 kbps AAC with artwork. Choose 320 kbps and the details come along.
3Lossless rips in ALAC: CD quality or better. Choose 320 kbps, or keep a copy as WAV for editing.
4Zoom and meeting apps that save sound only: speech, often stereo. 128 kbps is plenty.
5Exports from music apps and Android recorders: check whether it is music or speech, then pick 192 or 128 kbps.

Going from AAC to MP3 without losing more

AAC and MP3 both drop detail to save space, so converting one to the other loses a little each time. Give the MP3 some room above the source: a 256 kbps AAC song becomes a 320 kbps MP3, a 128 kbps recording a 192 kbps MP3 if it is music, or 128 kbps if it is speech.

If the file will be edited, cut or mixed, choose WAV instead and convert to MP3 once at the end. When you later need the MP3 again, use WAV to MP3.

M4A to MP3 on a Mac, iPhone and Windows PC

On a Mac, the built-in music app can make MP3 versions of songs in your library: its import settings let you pick the MP3 encoder, and the Convert command then creates an MP3 version next to each song. It handles one library at a time and doesn’t take voice memos outside it.

An iPhone has no built-in way to make an MP3. Open this page in Safari, choose the files from the Files app and save the results there. On Windows, a free media player with a convert menu and an MP3 profile works one file at a time.

M4A to MP3 on the command line

If you use the command line, this line converts one file at 192 kbps: ffmpeg -i in.m4a -c:a libmp3lame -b:a 192k out.mp3. Swap 192k for 320k for music. It keeps most tags, but the cover art needs extra options.

Files that won’t convert

Some M4A files are locked to the app that sold them. The converter recognises them and says so.

1M4P files: songs bought from iTunes before 2009 carry copy protection and play only in Apple’s apps.
2Apple Music downloads: songs saved for offline listening on a subscription are protected the same way. Songs you bought outright are not.
3Audiobooks from stores like Audible use their own protected formats; M4B files without protection convert as one long MP3.

Converting a whole album? Add every track at once. The MP3s keep their names and track numbers, so they sort in the right order in any music app.
