FLAC is the audiophile's handshake: CD-perfect sound at roughly half the shelf space. Free Lossless Audio Codec: think ZIP for sound: it decompresses back to the exact original.

What compressing FLAC actually does
Honest answer first: FLAC is already losslessly squeezed: think ZIP for sound: so a compressor can't make it much smaller without changing what it is. Flippy re-encodes at your chosen quality; for a dramatic cut, going lossy (MP3 or AAC) is the real lever, and we'll say so rather than pretend.

Questions people ask
How much smaller will my FLAC get?
It depends on how generously it was encoded: FLAC typically runs around 5 MB per minute: half of WAV, five times an MP3, and most files give up 30–70% at the medium preset before quality visibly suffers.
Will I lose quality working with FLAC here?
FLAC keeps every sample, so quality decisions only enter when you choose a lossy output: and Flippy will be upfront about that trade.
