MP3
MP3 is a lossy compressed audio format built for small files and broad playback compatibility. It works on almost every phone, browser, car stereo, media player, and editing application.
M4A
M4A is an audio-only MPEG-4 file, usually holding AAC audio. It is the format of iTunes Store purchases and plays in Apple Music and on iPhone, Mac, Android and Windows, as well as in web browsers.
FILE FORMATS
SOURCE
MPEG-1 Audio Layer III has been the universal music format since the 1990s. It compresses audio by removing sounds the ear is unlikely to hear, so a song takes a few megabytes instead of tens. ID3 tags carry the title, artist and album art, and every phone, browser, car stereo and editor plays it.
TARGET
M4A is an MPEG-4 audio file, usually AAC and sometimes Apple Lossless, with iTunes-style tags and album art. It is the format of iTunes Store music, iPhone voice memos and Apple Music libraries, and Android, Windows and browsers play it too. At the same bitrate, AAC in M4A sounds better than MP3.
| Feature | MP3 | M4A |
|---|---|---|
| Developed by | MPEG (Fraunhofer) | Apple / MPEG |
| File extension | .mp3 | .m4a |
| Compression | Lossy | Lossy (AAC) or lossless (ALAC) |
| Size vs uncompressed WAV | About 1/7 to 1/10 | About 1/10 (AAC) |
| Tags and cover art | ID3 tags and cover art | iTunes tags and cover art |
| Best for | Music and podcasts everywhere | Apple Music and iPhone libraries |
| Plays on phones and browsers | Yes | Yes, most devices |
USE CASES
Practical workflows where MP3 to M4A conversion is useful.
Match an AAC music library
If your Apple Music library is AAC, convert stray MP3s to match. Title, artist, album and cover come along.
Stream audio from a website
The M4A's index is placed at the start of the file, so browsers can begin playing it before the download finishes.
Meet an app or upload form that asks for M4A
Some apps and upload forms accept AAC or M4A audio only. Convert the MP3 to meet that requirement.
Show the right album art in Apple Music
When an MP3 has several pictures, the one marked as front cover becomes the album art, so a back cover does not show up instead.
Keep tags in any script
Titles and artist names in non-Latin scripts are kept in the M4A's tags.
Match iPhone Voice Memos
Mixing MP3 recordings with iPhone Voice Memos? Convert the MP3s so every recording is an .m4a file.
Convert mono lectures and interviews
Mono recordings stay mono in the M4A and are encoded at 96 kbps AAC; stereo files get 192 kbps.
Add M4A audio to an RPG Maker MV project
RPG Maker MV projects use .m4a files alongside .ogg for playback on Apple devices. Convert the MP3 to provide the .m4a copy.
Bundle AAC audio in an iOS app
App developers often ship sounds and music as AAC in .m4a, which iPhone and iPad play natively.
Convert a whole album at once
Add every track of an album to one job. Each M4A keeps its own tags and cover.
SUPPORTED FILES
MP3 files of any common bitrate are supported.
Songs and albums with ID3 tags and artwork.
Spoken-word MP3s.
Channels are kept as they are.
Title, artist, album and cover move into iTunes tags.
Upload many MP3s and download the M4A files together as a ZIP.
TROUBLESHOOTING
These explain most surprises.
01
MP3 to AAC is lossy to lossy, so the M4A can't add back detail the MP3 removed.
02
Only artwork embedded in the MP3 carries over.
03
Check album and album-artist tags in the MP3 and re-add the files.
04
AAC at good quality uses a similar bitrate to a well-encoded MP3.
05
Some older players read MP3 but not M4A. Keep the MP3 for those.
06
Check the MP3 plays normally. A damaged file stops with a short message.
Audacity, foobar2000, fre:ac and Apple's Music app can all convert audio once they are installed and set up. dragdropdo is built for turning MP3 into M4A quickly, from any device.
