FLAC: what it’s for
FLAC is lossless compression for music lovers: bit-for-bit identical to the CD or studio master at roughly half the WAV size. Archive in FLAC, convert copies to MP3 for the car, the gym, and anywhere storage matters.
Strengths
- Bit-perfect — decodes to the exact original samples
- Roughly half the size of WAV with zero quality cost
- Open and royalty-free, with tagging that WAV lacks
- Our tools convert FLAC to MP3 or WAV locally
Honest limits
- Still 3–5x larger than high-bitrate MP3
- Apple's ecosystem prefers ALAC — convert for iTunes-first setups
- Some car stereos and cheap players skip FLAC
- Overkill for voice recordings — MP3 or M4A serve better
