When FLAC to MP3 is the right move
Keep FLAC as your archive/master format, and export MP3 copies for daily use. This gives you portability without touching your original lossless files.
- Share albums quickly without multi-GB folders
- Sync more tracks to phones with limited storage
- Improve compatibility with legacy players and car units
Recommended export settings
- Portable listening: 192 kbps stereo
- Critical listening: 256 or 320 kbps stereo
- Sample rate: keep source rate unless you have a specific reason to change it
Common FLAC to MP3 pitfalls
- Converting your only copy: keep FLAC originals and create MP3 duplicates.
- Choosing very low bitrate: for music libraries, avoid going below 160 kbps.
- Batch mismatch: keep album tracks on the same bitrate to avoid audible differences.
