Comparison
FLAC vs WAV: Which Lossless Format Is Better?
FLAC vs WAV compared — compression, compatibility and quality, and which lossless format to choose for mastering, archiving and delivery.
FLAC and WAV are both lossless — they preserve your music perfectly — but they differ in file size, compression and compatibility. Here's how to choose.
FLAC
- Lossless compression
- ~50% smaller than WAV
- Supports rich metadata tags
- Open source, royalty-free
- Great for archiving and delivery
WAV
- Uncompressed, lossless
- Largest file size
- Universal studio standard
- Simplest possible format
- Best for interchange
The Verdict
Use WAV for studio interchange and FLAC for efficient lossless archives and distribution. Either choice preserves 100% of your master.
Same quality, different size
Both FLAC and WAV reproduce the exact original audio data. FLAC compresses to about half the size of WAV with zero quality loss.
WAV is the simplest format but the largest; FLAC adds compression smarts while remaining perfectly lossless.
Compatibility
WAV plays everywhere and is the universal interchange format in studios. FLAC is widely supported by players and streaming platforms, while Apple's ecosystem natively prefers ALAC.
For mastering sessions and exchange with engineers, WAV is the safe default. For archiving and distribution, FLAC is efficient and future-proof.
Recommendation
Keep WAV as your production/interchange format and FLAC (or ALAC) for archives and delivery — both guarantee full fidelity.
Zaventra Music Group accepts both for distribution.
