Convert FLAC to MP3 online
Convert FLAC to MP3 when a lossless library is too large for a phone or a player that cannot read FLAC. The audio is encoded with LAME at VBR quality 2 — about 190 kbps, which is where most listeners stop being able to pick out the difference on normal equipment.
When should you convert FLAC to MP3?
- Fit a lossless collection onto a phone or a car stereo
- Share music with someone whose player will not open FLAC
- Upload to a service that only accepts MP3
- Cut storage by roughly three quarters
Before you convert
Keep the FLAC
This is the one direction that genuinely loses something. The FLAC is your master; the MP3 is a listening copy you can always regenerate.
Not every player is the problem
FLAC support is broad now. Check whether your device actually rejects it before converting a whole library.
What happens to your file
The FLAC audio is decoded and re-encoded to MP3 with libmp3lame at VBR quality 2 (~190 kbps). There is no video stream involved, so the job is quick even for long recordings.
Settings this conversion runs with
| Engine | ffmpeg |
|---|---|
| Output codec | libmp3lame |
| Setting | VBR quality 2 (~190 kbps) |
| Compression | Lossy |
What changes
- FLAC holds the full waveform, and MP3 does not. This pass permanently discards the parts of the signal the codec judges inaudible — keep the FLAC file if it is your master.
- Cover art, lyrics, and most tags are not carried across — the output keeps the audio, not the metadata around it.
