Voice memos and AAC recordings are often M4A. Drop the file, pick a bitrate, and your browser decodes it and saves an MP3. The audio never goes to a server.
M4A files people convert
- Turn an iPhone voice memo or an AAC download into an MP3 more players accept.
- Use 128 kbps for speech and 320 kbps for music.
- The M4A stays on this device. Nothing is uploaded to finish the conversion.
How to use the M4A to MP3 Converter

Drop your M4A

-
Pick a bitrate
320 kbps for music, 192 kbps for everyday listening, 128 kbps for voice memos.

Convert and download
Click Convert to MP3. The file is decoded and encoded on your device, then downloaded.
Voice memos and AAC, not a video
This page converts M4A and AAC audio into MP3. Voice memos and most AAC downloads are AAC inside the M4A, and those decode in the browser. Apple Lossless (ALAC) stored in an M4A often will not. Convert that file to AAC or WAV first, then bring it here.
An MP4 video belongs on MP4 to MP3. That page takes the soundtrack off the picture. This page is audio only.
What the MP3 keeps
MP3 is lossy. The menu is the usual bitrate choice:
- 320 kbps when the memo or the song should stay close to the AAC.
- 192 kbps for speech you will still listen to.
- 128 kbps when the file mainly needs to be small enough to send.
Tags are not copied
Title, artist, and cover art are not carried over. The MP3 is written without metadata. Put them back with the MP3 tag editor if the player needs a name.
Keep the M4A if you still need the original. The conversion does not upload the file. Trim or cut after you have the MP3, on the trimmer or the cutter, if the memo has silence at the ends.
M4A to MP3 Converter FAQ
Can I convert M4A to MP3 on iPhone, Android or Mac?
Yes — the converter runs in your browser, so iPhone, Android, Mac, Windows or Linux all work the same way: open the page and drop the file. Inside the M4A you need AAC audio, which is what voice memos and most AAC downloads use. Apple Lossless (ALAC) stored in an M4A often will not decode in a browser — convert that file to AAC or WAV first, then bring it here.
What about MP4 video?
Use the MP4 to MP3 converter for video files. This page is for audio: M4A and AAC.
Will converting to MP3 lose quality?
MP3 is lossy. At 320 kbps the difference from the AAC original is small for almost everyone. Keep the M4A if you need the original file untouched.
Are tags and artwork kept?
No. The MP3 is written without metadata, same as the WAV converter. Title, artist and cover art are not copied.
Does the file get uploaded?
No. Your browser decodes the M4A and encodes the MP3 locally. The audio stays on your device.
