Why convert M4A to AIFF?
M4A — Apple's standard format for songs. Sounds a little better than MP3 at the same size.
AIFF — Apple's version of WAV. Top sound quality, large files.
One thing to keep in mind: a M4A file has already had some of its sound removed to keep the file small. Saving it as AIFF keeps what's there but cannot put the missing sound back. This kind of conversion is for when a program or app needs a AIFF file, not for making the song sound better.
All of this happens right inside your web browser. Your file stays on your phone or computer the whole time.
Frequently asked questions
No. M4A files have already had some sound removed to make them small. Saving them as AIFF keeps everything that is there now, but it cannot bring back the missing sound. AIFF is most useful when you start from a perfect-quality file in the first place.
