How to use M4A to MP3 Converter

  1. 01Upload your M4A file.
  2. 02Pick an output quality — Standard (192 kbps) works well for most recordings.
  3. 03We re-encode the audio to MP3 using FFmpeg's LAME encoder.
  4. 04Download your MP3 file.

Quality and privacy

We use FFmpeg on the server for processing. Files are placed in isolated temporary storage and deleted automatically after one hour. When an operation can copy an existing audio stream, we identify it instead of claiming an unnecessary re-encode is lossless.

Frequently asked questions

Can I convert an iPhone voice memo to MP3 with this tool?
Yes. iPhone Voice Memos are saved as M4A files — upload the file here and it converts straight to MP3.
Does converting M4A to MP3 lose quality?
M4A (AAC) and MP3 are both lossy formats, so converting between them involves re-encoding. At 192 kbps or higher the difference is inaudible for almost all listening.
