The converter defaults to the highest practical bitrate for FLAC. Since FLAC is lossless, every sample is preserved exactly. No encoder settings to worry about.
Garbage in, garbage out. The output quality depends on your source. A 128kbps WAV file won't sound better in FLAC. Start with the best source available.
AudioUtils processes everything locally using WebAssembly. The encoder runs at near-native speed. A 10-minute file converts in seconds with maximum quality settings.
Frequently Asked Questions
Is WAV to FLAC truly lossless?
Yes, 100%. FLAC compression is mathematically lossless. You can convert WAV to FLAC and back to WAV and get a bit-identical file. No audio data is lost.
How much space does FLAC save over WAV?
Typically 40-60%. A 50MB WAV file becomes roughly 25-30MB as FLAC. The exact ratio depends on the audio content — simpler sounds compress better.
Can all devices play FLAC?
Most modern devices support FLAC. Android has native support. iPhone added FLAC support in iOS 11. Windows supports it natively in Windows 10+. Older devices may need MP3 or AAC instead.
Should I keep my WAV originals after converting to FLAC?
Not necessary. FLAC is lossless — you can always convert back to WAV with identical quality. Many professionals archive exclusively in FLAC to save storage.
