FLAC is the audiophile's format — every detail of the original preserved, nothing discarded. The limitation is that not everything plays it: older phones, some music players, certain streaming apps and various portable devices either don't support FLAC or handle it unreliably. Converting to MP3 for those devices — while keeping the FLAC originals — gives you the best of both.
How to Convert
- Open FLAC to MP3.
- Upload the FLAC file.
- Choose a bitrate — 320 kbps for music you care about; 192 kbps for general use.
- Convert and download the MP3.
Always Keep the FLAC
The FLAC is your master copy. MP3 conversion is a one-way process — once quality is discarded, it's gone. Keep the FLAC archived and use the MP3 as the playback copy for devices that need it. This is the same principle as keeping a RAW photo file after exporting a JPG.
Choosing the Right Bitrate
For music converted from FLAC:
| Bitrate | Good for |
|---|---|
| 192 kbps | General listening, everyday music |
| 256 kbps | Music where quality matters |
| 320 kbps | Maximum MP3 quality; closest to lossless |
For a full explanation of what bitrates mean in practice, see what is audio bitrate: 128 vs 192 vs 320 kbps.
When FLAC Support Has Improved
Modern iPhones (iOS 11+) and recent Android phones support FLAC natively. Many streaming apps and music players now support it too. Check whether your device or app already plays FLAC before converting — if it does, there's no need to convert for that device.
Common Scenarios for FLAC to MP3
- Adding music to an older car stereo or MP3 player.
- Uploading to a service that only accepts MP3.
- Sharing a track with someone who doesn't have a FLAC player.
- Building a smaller "listening" library while keeping the full lossless archive.

Batch Converting a FLAC Library
If you have a large collection of FLAC files that you want as MP3 for a phone or portable player, converting them individually is time-consuming. Most desktop audio tools (fre:ac, dBpoweramp, Foobar2000 with the Converter component) handle batch conversion of entire folders. For individual files or occasional conversions, FLAC to MP3 is the quickest route. For understanding why the conversion from FLAC to MP3 produces excellent results, the explanation is in lossless vs lossy audio: what you actually hear — at 320 kbps, the difference is inaudible to most people even on good equipment.
