Lossless audio in about half the space of a WAV. FLAC keeps every sample but packs it tightly, which makes it the favourite for music collections and archives. Most players and Android phones play it; Apple Music and iTunes don't.

The audio format almost everything plays. MP3 makes small files by leaving out detail most ears won't miss, which makes it the safe choice for music, podcasts and voice notes you want to share, upload or keep on a phone.

Your music is in FLAC but your phone, car or player doesn't play it, or you want a collection that fits in a fraction of the space.
A 4-minute track in FLAC is typically about 24 MB. As an MP3 at 320 kbps — where this page starts — it's about 9.2 MB; at 192 kbps, about 5.5 MB.
320 kbps: a FLAC has lost nothing yet, so it's worth giving the MP3 the most it can hold, and it's still around a third of the FLAC's size. 192 kbps is fine if space matters more.
Every phone, car stereo, music app and player — including iTunes and Apple Music, which won't play FLAC.
