Convert FLAC to MP3 for Any Player

FLAC keeps every detail of the original, which is why a single album can take 300MB or more. Many car stereos, older players and phones play MP3 but not FLAC. Convert a track here to a 256 or 320 kbps MP3 that's a fraction of the size, on your own device.

Your file never leaves your device. Nothing is uploaded.

How it works

  1. Pick a file. Drag in a recording, a voice memo or a video. It opens in this tab; nothing is sent to a server.
  2. Choose the format. MP3 or M4A for small files that play anywhere, WAV or FLAC when you need lossless audio, OGG for the web. Set the quality if you like.
  3. Download it. Your browser converts the file and saves the result to your device. If you need a transcript, send the new file to the free Wave AI transcription tool in one click.

Common questions

Which bitrate should I use for FLAC to MP3?

320 kbps, the MP3 maximum, if the music matters to you; 256 kbps is very hard to tell apart for most listeners and a bit smaller. Keep the FLAC files as your master copy.

Are my FLAC files uploaded?

Nowhere. The converter runs inside your browser tab, so the file is read and converted on your own device and saved straight back to it. It is never uploaded to Wave or anyone else, and we never see its name or contents.

Are the tags kept?

Yes. Title, artist and album tags are copied into the MP3. Embedded cover art is dropped to keep the file small.

Can I convert a whole album at once?

One file at a time for now. Once the converter has loaded, each track takes a few seconds on a recent computer.
