How to convert FLAC to MP3

  1. Drop the audio.
  2. Pick a bitrate.
  3. Press Convert and download.

What happens to your file

The lossless audio is decoded and encoded as MP3 at your bitrate: 320 kbps is transparent to nearly everyone, 192 to most. Keep the FLAC as the master.

Tags (artist, album, artwork) inside the FLAC are not carried into the MP3 yet.

Questions

Is 320 kbps worth it?

From a FLAC source, yes if space allows — it is the one bitrate that survives blind tests. 192 is the sensible everyday choice.

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "audio.convert",
    "options": {
      "format": "mp3",
      "bitrate": 192
    }
  }'

The same operation, audio.convert — mp3, wav, aac, flac, ogg, opus or aiff out of whatever came in. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
