Drop in a FLAC track and get an MP3 at up to 320 kbps for a player, car or phone that doesn't take FLAC. The file never leaves your browser.

Runs in your browser. Nothing is uploaded.

## How to use it

1. **Add the FLAC.** Drop the track or choose it.
2. **Pick a bitrate.** 320 kbps keeps the most from the lossless source.
3. **Convert and download.** Play the MP3 to check it, then download it.

## Lossless to lossy

FLAC compresses audio without any loss, so it's the best source to make an MP3 from: the MP3 is encoded once, from the full sound. Keep the FLAC as your archive and make MP3s for devices that don't play FLAC or have little space.

An MP3 at 320 kbps takes about 2.4 MB a minute, usually well under half a CD-quality FLAC. At 192 kbps it's about 1.4 MB.

## Tags and hi-res files

Tags such as title, artist and album carry over into the MP3. Hi-res FLAC converts too, but MP3 keeps no bit depth and tops out at 48 kHz, so a 96 kHz track comes out at 48 kHz.

## With ffmpeg

The same conversion at 320 kbps on the command line:

- ffmpeg -i track.flac -codec:a libmp3lame -b:a 320k track.mp3

## Questions

### Is my music uploaded?

No. The FLAC is decoded and the MP3 is written in your browser.

### Which bitrate should I pick?

320 kbps for the closest copy of the lossless original, 192 kbps to save space with little audible difference for most listening.

### Are the title and artist kept?

Yes. The FLAC's tags are copied into the MP3.

### Can I convert a whole album at once?

One track at a time. For a whole folder, the ffmpeg command above can run in a loop.
