FLAC to MP3 converter

Make lossless FLAC playable on everything — car stereos, old players, tiny storage. Conversion happens in your browser — the file never touches a server.

FLAC stores audio without throwing any data away, which is great for archiving but overkill for most listening — and it's the one format a surprising number of devices still refuse to open. An MP3 converter re-encodes that lossless source into a compressed file that plays on virtually anything with a speaker: factory car head units, Bluetooth receivers, gym equipment, older iPods, and cheap USB players that choke on FLAC. The trade is deliberate — you accept a lossy copy in exchange for a file roughly a quarter to a third of the size that no device will reject.

When you convert, you pick a bitrate that sets the quality-to-size balance. 320 kbps constant bitrate is the practical ceiling most people can't distinguish from the original in casual listening, while a variable setting like V0 lands near the same quality with smaller files by spending bits only where the music needs them. Because everything runs locally in your browser, there's no upload wait and no queue — the decode and re-encode happen on your own CPU, so a typical track finishes in seconds and nothing about your file is stored or transmitted.

When to use it

  • You bounced a track out of an editor as FLAC and want a 320 kbps MP3 for casual sharing or a platform that re-encodes audio anyway — like the soundtrack of a YouTube video, where a lossless master makes no difference to the final result but the smaller MP3 uploads faster.
  • Your car's USB port or older head unit won't recognize FLAC files, so you convert the album to MP3 to load onto a thumb drive that actually plays.
  • You're sending demos or reference mixes over email, WhatsApp, or Discord and need the smaller MP3 size to stay under attachment limits without the recipient needing a FLAC-capable player.

FAQ

Should I keep the FLAC?

Yes — treat FLAC as your master and MP3 as the travel copy. You can always re-make MP3s from FLAC, never the reverse.

How much quality is lost?

At VBR high, the difference is inaudible to nearly everyone on normal playback gear.

What bitrate should I choose when converting FLAC to MP3?

For general listening, 320 kbps CBR gives you the highest MP3 quality and is effectively transparent to most ears. If file size matters more, V0 (a variable bitrate around 220-260 kbps) sounds nearly identical while saving space. Go below 192 kbps only for spoken word or when storage is genuinely tight.

Can I convert several FLAC files to MP3 at once?

Yes — you can queue multiple FLAC files and convert them in one batch, with each one encoded locally on your device. Since processing happens in the browser rather than on a server, the speed depends on your computer's CPU rather than an upload connection or a shared queue.

Does converting FLAC to MP3 keep the track title, artist, and album art?

Standard metadata tags like title, artist, and album generally carry over from the FLAC's Vorbis comments into MP3 ID3 tags. Embedded cover art support can vary, so if artwork or a specific tag doesn't survive, check the file afterward in a tag editor and re-add anything missing.
