What actually changes
CAF and MP3 are not the same picture in two wrappers.
The audio inside the CAF container is decoded and encoded as MP3.
Worth knowing first
CAF is a container designed to hold almost anything, including raw PCM, ALAC, AAC and IMA4. Two .caf files can therefore be completely different in quality and size, and the extension gives you no way to know which you have before converting.
Questions
CAF to MP3, answered
Why does Apple use CAF?
It has no 4 GB size limit, unlike WAV and AIFF, which matters for long recordings and sample libraries.
Is the audio lossless?
Only if the CAF holds PCM or ALAC. Check the codec reported by the conversion before assuming.
