WAV (.wav) · Max 20 MB
Traditional online converters upload your file, process it on a remote server, and send it back. That's slow, insecure, and wasteful. AudioUtils eliminates the upload entirely.
The converter uses WebAssembly to run a compiled audio engine in your browser tab. It reads your file locally, converts it locally, and saves the result locally. The network is never involved.
This matters for sensitive audio. Unreleased music, legal recordings, private conversations. With AudioUtils, your files stay yours. Both WAV and FLAC are lossless. This conversion preserves every sample. No quality is lost.
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.
