Upload a WAV file and get a FLAC back. No signup, no watermark, no limit on how many.
WAV is raw, uncompressed PCM in a Microsoft container: the audio exactly as it was sampled, with nothing clever done to it.
Where you run into it: Recording sessions, sample libraries, video editors, anything that has to be edited rather than merely listened to.
What it costs you: It is enormous — roughly 10 MB a minute in CD-quality stereo — and it carries almost no tagging, so a folder of WAVs is a folder of filenames.
FLAC compresses losslessly: it typically halves a WAV and gives back bit-for-bit the same audio when decoded. It is free, open, and widely supported outside Apple's world.
Where you run into it: Archived rips, Bandcamp and Qobuz downloads, anyone who keeps a music library they intend to still have in ten years.
What it costs you: Half of enormous is still large, and some hardware — car head units especially — will not touch it.
This is the conversion in this group that costs nothing and gives you something. FLAC compresses without discarding: decode the result and you get the same samples back, bit for bit, at the same rate and the same depth — a 24-bit WAV stays 24-bit. It also writes a checksum of the audio into the file, so the archive can prove later that it has not quietly rotted, and it brings a tag system, which is the thing WAV never really had.
This is the right step for CD rips, field recordings and finished exports you intend to keep, and it is the one case in this group where deleting the source afterwards is safe — the FLAC holds the same audio and can prove it. Two things to know. A WAV's written tags do come across, but a WAV rarely has any, so expect to tag the FLAC yourself; that is a gain in the destination rather than a loss in transit. And if the file is going somewhere rather than staying, check that the destination reads FLAC first — plenty of older editors, hardware samplers and car units still read WAV and nothing else.
Yes, entirely, and there is no cap on how many files you convert. No account, no watermark, no trial.
None. It is an exact transformation: compress, decompress, and every sample is identical to the one you started with. There is nothing to decide and no setting to get wrong, which is why FLAC is what archives and lossless download stores standardised on. If the result ever fails to decode, that is corruption to investigate rather than a compromise you accepted.
About half, typically, though the figure depends on the music rather than on any setting — quiet and sparse material compresses further than dense loud material, and a 24-bit recording compresses less well in proportion, because the lowest bits of each sample are close to random and offer the encoder no pattern to find. FLAC's compression levels change only how long the encoder thinks about the problem, never what comes out.
Yes — FLAC is one of the formats this converter writes, so the reverse page exists at /flac-to-wav/. Both formats are lossless, so this round trip is exact: decode what comes back and you have the samples you started with, bit for bit. Only the file size changes, which makes this the one pair you can convert back and forth as often as you like.
The file is uploaded to do the conversion — nothing here runs in your browser — and both your upload and the converted result are deleted the moment the file is sent back. Nothing is stored and nothing is logged beyond the request itself.
