How to do it, step by step
- Select the M4A files.
- Choose the MP3 Bitrate (192k suits most cases).
- Click Convert all.
- Download the MP3s.
When this is useful
iPhone voice memos
Send a recording to someone who cannot open M4A or attach it in systems that only accept MP3.
Music and podcasts in M4A
To play in cars, radios and players that only read MP3.
Tips for a good result
- Use 192k or more: M4A and MP3 are lossy formats, and converting between them already loses a little.
- For voice recordings, 128k is usually enough.
What this tool does not do
- M4A already has lossy compression: converting to MP3 adds new compression, and the quality may drop a little.
- M4A protected by DRM (old store purchases) cannot be read.
- The new file carries the “WebFaz.com” credit in the metadata (comment and artist).
Frequently asked questions
- Does it lose quality when converting?
- A little, because both formats compress with losses. High bitrates reduce the difference.
- Does it work for video audio?
- To take the audio from a video, use WebFaz Audio Extractor.
