Where FLAC files come from
FLAC is the compressed lossless archive; WAV is the uncompressed working copy. The conversion happens when audio leaves a library and enters a tool that only reads PCM.
What changes when you convert FLAC to WAV
| Encoding | FLAC decompressed to PCM, sample for sample identical |
|---|---|
| File size | Roughly doubles |
| Quality | Bit-perfect, with no loss at all |
Worth knowing first
This one really is lossless in both directions, so nothing is at stake beyond disk space. The catch is tags: FLAC carries rich metadata that WAV has almost nowhere to store, so artist and album information is left behind.
FAQ
Is this genuinely lossless?
Yes, completely. FLAC is compressed the way a ZIP file is, so decompressing returns the original samples exactly. You can go back to FLAC later and get a bit-identical file.
Then why does FLAC exist if WAV is the same audio?
Size and metadata. FLAC stores identical audio in about half the space and carries proper tags. WAV wins only where a tool refuses to read anything else.
What happens to my tags?
They are lost. WAV has no widely respected tagging standard, which is one of the main reasons music libraries use FLAC rather than WAV for storage.
Is this FLAC to WAV converter free, with no upload?
Yes. Conversion happens locally in your browser via FFmpeg WebAssembly — your audio never uploads. No signup and no watermark. Length is limited only by the memory your browser gives this tab, which is far smaller on a phone than on a computer.
