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.
Both sides are lossless, so this conversion is exact: decode the result and you get back the same samples you started with, bit for bit. Only the size and the container change. Nothing is at risk here, which makes it the one conversion you can run on an only copy without thinking twice.
Yes, entirely, and there is no cap on how many files you convert. No account, no watermark, no trial.
No. Both formats are lossless, so the result decodes to exactly the same samples as the original — bit for bit. Only the file size changes.
It depends which way you are going: FLAC typically stores the same audio in about half the space of WAV or AIFF, so the file either roughly halves or roughly doubles. The audio itself is identical either way.
Yes — FLAC is one of the formats this converter writes, so the reverse page exists at /flac-to-wav/. Remember that going back and forth between two lossy formats degrades the audio a little each time.
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.
