About FLAC files
Any FLAC up to 10 GB converts to MP3 on Audo without an account, free for the first hour of each file, 10 times a day. A 3-minute song usually takes about 4 seconds.
FLAC shrinks audio with nothing lost: played back, it's identical to the original. Music stores such as Bandcamp offer FLAC downloads, and many people rip their CDs to it. It's smaller than WAV but still several times bigger than an MP3.
Keep the FLAC files as your originals, and make MP3s from them when you need them. For an app that doesn't open FLAC, pick WAV instead: exactly the same sound, uncompressed.
Questions
How do I convert FLAC to MP3 on a Mac or Windows PC?
In your browser: add the FLAC at the top of this page, keep MP3, and download it. There's nothing to install, on a Mac, a Windows 11 PC, or a phone.
Does FLAC really sound better than MP3?
It keeps more: a FLAC holds every detail, and an MP3 leaves some out. Hearing it is another matter, since most people can't tell a 192 kbps MP3 from the FLAC it came from.
Which bitrate should I pick?
Leave it at 192 kbps, the default from FLAC, for everyday listening. For the most detail, pick 320 kbps under More options: it's the highest bitrate MP3 has.
Is there a free FLAC to MP3 converter?
Yes. On Audo, the first hour of each file converts free, 10 times a day, with no sign-up. That's longer than nearly any song, and longer albums are $0.01 a minute ($0.60 an hour) with no subscription — see pricing.
What are the disadvantages of FLAC files?
Size and support. A FLAC is several times bigger than an MP3, Apple's Music app on a Mac doesn't import it, and some car stereos and older players can't play it.
Can I get M4A for my iPhone instead?
Yes. Pick M4A to get AAC sound, which Apple devices play and which usually sounds a little better than MP3 at the same size.
How big will the MP3 be?
At 192 kbps, about 1.4 MB a minute, so a four-minute song comes to roughly 6 MB.
Will the music stay as loud?
Yes. The MP3 matches the FLAC's level. A track mastered right up to the top is brought just under it, so the MP3 never clips.
