FLAC → MP3

Private by design

Convert FLAC to MP3 without uploading a thing.

FLAC is lossless, so it preserves every detail — and takes a lot of space. Converting to MP3 frees up storage and fits more music on phones and players, with a quality drop most people can't hear at high bitrates.

About FLAC → MP3. FLAC is lossless, so this is your one clean encode from a perfect source. Use 320 kbps to keep the MP3 as close to the original as a lossy format allows.

What is FLAC?

FLAC (Free Lossless Audio Codec) compresses audio without discarding any data — bit-for-bit identical to the source when decoded. Audiophiles love it for archiving; the trade-off is file size, which is why people convert to MP3 for everyday listening.

How to convert FLAC to MP3

  2. Pick a bitrate — 320 kbps for best quality, 192 kbps for a smaller file.
  3. Click Convert to MP3. It runs in this tab, on your device.
  4. Download your MP3. Nothing was ever uploaded.

FAQ

Should I keep my FLAC files after converting?

Yes, if you have the space. FLAC is your lossless master — keep it for archiving, and use the MP3 for phones and players. You can always re-encode from the FLAC later.

What's the best bitrate for FLAC to MP3?

320 kbps. Since you're starting from a lossless source, a high bitrate gives you the best-sounding MP3 the format can produce. It's the one conversion where going maximum quality clearly pays off.

How much smaller will the MP3 be?

Typically 3–5× smaller than the FLAC, depending on the music. That's the whole point — fitting far more audio on a device with a quality difference most listeners won't notice.
