About the formats
M4A
MPEG-4 Audio

MP3 is the most widespread audio format in the world. Lossy compression shrinks files to about a tenth of WAV, and it plays on every device.
Frequently asked questions
Is converting M4A to MP3 free?
Yes, completely free. No account, no daily limit, no watermark and no queue.
Does it work on a phone?
Yes. It works on iPhone, iPad and Android, with no app to install.
Is there a file size limit?
There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
