FAQs

Will MP3 to FLAC improve quality?

No. FLAC is a lossless container, but what goes in is still audio that MP3 already degraded. What it guarantees is "no further loss from here" — not recovering what's gone.

So why convert at all?

Three real reasons: 1) unify an editing library in FLAC so repeated exports stop degrading; 2) some players/devices accept FLAC only; 3) one format across a mixed library is simply easier to manage.

How much bigger will files get?

Roughly 5-10x: a 128kbps MP3 at ~4MB becomes a 25-40MB FLAC. You're trading size for format consistency and a clean workflow.
