Why convert AIFF to M4A?
AIFF — Apple's version of WAV. Top sound quality, large files.
M4A — Apple's standard format for songs. Sounds a little better than MP3 at the same size.
AIFF keeps the song exactly as it was recorded. M4A makes a much smaller file by leaving out parts of the sound most people can't hear. At the standard quality setting, the difference is hard to notice for most listeners on most devices.
All of this happens right inside your web browser. Your file stays on your phone or computer the whole time.
Frequently asked questions
Not quite. M4A makes the file smaller by leaving out parts of the sound that most people cannot hear. At the standard quality setting, almost nobody can tell the difference, but it is not exactly identical to the original.
