Why convert WAV to FLAC?
WAV is uncompressed studio quality, ideal for editing and mastering. Converting it to FLAC gives you a lossless, edit-ready file — lossless compression — CD-perfect quality at roughly half the size of WAV.
This converter runs the same FFmpeg engine desktop tools use, compiled to WebAssembly and executed entirely in your browser. Your WAVnever touches a server — which is why it's private, works on slow connections, and has no queue. You can also trim, fade, merge and batch-convert in the same step.
Frequently Asked Questions
How do I convert WAV to FLAC for free?
Drop your WAV file into the tool above (or click to browse), then hit Export. The output is already set to FLAC. It converts instantly in your browser and downloads — no signup, no watermark.
Is my WAV file uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly (FFmpeg). Your WAV file never leaves your device, which is why it works offline and stays private.
Will converting WAV to FLAC lose quality?
Converting to FLAC is lossless, so no quality is lost in the container change. Note that if the source WAV was already lossy, FLAC preserves that quality but can't add back detail the original never had.
Can I trim or fade the audio while converting WAV to FLAC?
Yes — drag the waveform handles to trim, add fade-in/out, adjust volume or bitrate, then export. You can also drop several WAV files to batch-convert or merge them into one FLAC file.
