Add your WAV file
Drop one or more .wav files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.

Re-encoding .wav audio as .flac changes how the sound is compressed and which players will accept it. A .wav file is Microsoft's Waveform Audio format, which in practice almost always stores uncompressed PCM samples. Because every bit of the original signal is preserved and no decoding is required, .wav remains the default working format in recording studios and audio editors.
A .flac file contains audio compressed with the Free Lossless Audio Codec, which shrinks recordings without discarding a single sample. Decoded .flac output is bit-identical to the source, so the format has become the standard for music archiving and high-resolution downloads. For this route the practical draw is genuinely lossless while roughly halving storage and open specification with no royalties anywhere in the chain — balanced against still several times larger than a good lossy encode, which is worth knowing before you commit a large batch.
Why convert WAV to FLAC?
The practical trigger for this conversion is usually a mismatch: with .wav, enormous compared with FLAC, which halves the size losslessly. Switching to .flac buys you genuinely lossless while roughly halving storage, which is why it is the better fit for ripping CD collections for permanent archival. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
WAV vs FLAC at a glance
| Aspect | WAV audio (.wav) | FLAC audio (.flac) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossless — every pixel or sample is preserved exactly |
| How it stores data | a RIFF chunk container whose fmt chunk usually declares linear PCM, though compressed codecs are technically permitted | linear prediction followed by Rice coding typically yields files 40 to 60 percent the size of raw PCM |
| Strongest at | capturing and mixing sessions in a DAW | ripping CD collections for permanent archival |
| Weak spot | enormous compared with FLAC, which halves the size losslessly | still several times larger than a good lossy encode |
| Metadata | rIFF INFO chunks hold basic tags, while the Broadcast Wave bext chunk and iXML add description, originator, and timecode for production workflows; some tools also embed ID3 chunks | vorbis comments for tags plus a dedicated PICTURE block for cover art; cue sheets can be embedded for whole-disc rips |
Pick FLAC as the output
Select .flac in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if FLAC is selectable, the route is real and validated.
Convert on your device
Press Convert. The transcode runs on an FFmpeg engine compiled to WebAssembly, so the audio never leaves your device.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid FLAC file. Outputs keep the original filename with the .flac extension.
WAV to FLAC questions, answered
Will converting WAV to FLAC lose quality?
Both sides are re-encoded, so expect a small generation loss controlled by the quality setting: wav is lossless-oriented and flac is lossless-oriented. For visually or audibly transparent results keep quality high; for smaller files lower it and compare.
Is it private to convert WAV files here?
Yes — the .wav file is processed inside your browser tab and never uploaded. The transcode runs on an FFmpeg engine compiled to WebAssembly, so the audio never leaves your device. Close the tab and the file is gone from memory.
Where will the FLAC file work?
All major browsers decode .flac, Windows 10 and later plus Android play it natively, and virtually every dedicated audio player supports it. The persistent gap is Apple's Music ecosystem, where converting to ALAC delivers the same audio in a supported wrapper.
Will the FLAC file be bigger or smaller than my WAV?
It depends on the content: linear prediction followed by Rice coding typically yields files 40 to 60 percent the size of raw PCM. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my WAV file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, rIFF INFO chunks hold basic tags, while the Broadcast Wave bext chunk and iXML add description, originator, and timecode for production workflows; some tools also embed ID3 chunks; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert FLAC back to WAV?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .wav → .flac → .wav is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
