FITS at a glance
FITS
Convert to FITS when preserving scientific image data, observation metadata, or instrument-derived captures for astronomy and research workflows.
It is the right target when measurement context matters as much as the picture itself.
ALAC at a glance
ALAC
Convert to ALAC when you need lossless music storage or delivery in an Apple-friendly format, especially for personal libraries, hi-fi playback, or archives that sync across Apple devices.
It is appropriate when quality must be preserved but uncompressed AIFF or WAV would be unnecessarily large.
For broader non-Apple-centric archival exchange, FLAC is often the more neutral choice.
