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 it once, not on every form

Fixing a file here means downloading it and going back to the form. The Fylane extension does this work inside the form instead, on the file you already have.

And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.

Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.

Filmed from the extension: three upload fields on a job application, filled from one tap.

Add to Chrome — freeWhat it does

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.
