1. Is ALAC as good as FLAC?

ALAC and FLAC are both lossless audio formats, so they provide the same sound quality. However, FLAC has a better compression ratio than ALAC, making FLAC a better choice if you want to save space. But if you want to open music files on Apple devices, ALAC is the better option.

2. Can I upload FLAC to Apple Music?

Since Apple Music does not support the FLAC format, you will not be able to upload FLAC files to Apple Music.

3. How do I import FLAC files into iTunes?

You can't import FLAC files directly into iTunes without first converting them to an iTunes-supported format (such as MP3, AAC, AIFF, WAV, or Apple Lossless).

4. Does converting FLAC to ALAC lose quality?

No, converting FLAC to ALAC will not degrade the sound quality as they are both lossless formats.
