Why convert FLAC to AAC?

Converting FLAC to AAC reduces file size and bandwidth for streaming and mobile playback while maintaining good audio quality in a widely supported format.

Will converting FLAC to AAC affect audio quality?

Yes, AAC is a lossy format, so the conversion results in irreversible quality loss from the original FLAC.

Can I keep metadata when converting to AAC?

Yes, metadata and artwork are preserved when using MP4/M4A containers but are limited in raw AAC streams.
