Convert WAV to FLAC

No — FLAC is lossless, so the audio is bit-for-bit identical to the WAV, just stored more efficiently. It is the right choice for archiving or sharing masters where quality matters but the WAV is too big.

No. Everything runs with WebCodecs on your device, so the audio never leaves the browser — no account, no quota, no size limit. Chrome, Edge and Firefox work best.

Usually around half the size, though it depends on the audio — dense, busy music compresses less than sparse recordings or speech. Because FLAC is lossless, that saving is free: you get roughly a 2:1 reduction with zero change to the sound. It is the ideal format for archiving a WAV you want to keep at full quality without paying full storage.

Not quite — FLAC support is wide but not universal. Most modern phones, media players and music software read it, but some older hardware, car systems and simple upload forms still expect WAV or MP3. FLAC is the right choice for storage and for players you know support it; if you need the broadest compatibility for playback, MP3 is safer, and if a specific editor demands uncompressed, keep the WAV.

Yes to both. FLAC stores the exact samples from the WAV, so it is bit-for-bit identical audio — nothing is approximated. You can decode it back to WAV at any time (the FLAC-to-WAV tool does exactly that) and land on the same uncompressed file you started with. That lossless round-trip is the whole point of FLAC over a format like MP3.
