Common questions
Why convert MP3 to M4A?
M4A (AAC) is the format Apple's ecosystem prefers — iPhone, iTunes and Apple Music handle it natively, and it's the format used for custom ringtones.
Will quality improve?
Converting can't add back detail an MP3 already discarded, but AAC is an efficient codec, so the M4A keeps the quality you have at a similar or smaller size.
Is M4A the same as AAC?
M4A is the container; AAC is the audio codec inside it. In everyday terms they're used interchangeably for Apple-style audio.
Is there a file size limit?
Free users get up to 25 MB without an account; Pro raises it to 500 MB per file with 3,000 credits a month.
