FLAC to WAV Converter

FLAC already halves a WAV without losing a sample, which means the decode step reads a compressed stream and the encode step writes a new codec from identical PCM. Free Lossless Audio Codec (FLAC) is a lossless audio format used for archiving music without sacrificing cd-quality data. Files saved as FLAC usually come from Xiph.Org. Before converting, check that the source is the highest-quality copy you have, because every later step can only preserve what is already there.

The target is Waveform Audio File Format (WAV), a uncompressed audio format chosen for recording. The target stores samples without perceptual loss, so the file grows considerably; it preserves the current quality but cannot recover earlier compression. The output keeps the original dimensions or sample rate unless you change them, so this step changes the encoding rather than the content.

WAV writes 16-bit PCM at 48 kHz, roughly 10 MB per minute. Nothing is lost and every editor imports it, which makes it the right pick for further editing rather than for streaming. Channel layout is preserved, so a stereo source stays stereo and a mono recording is not upmixed. The sample rate is preserved unless you change it; resampling would add another processing step and is best avoided. Expect a larger output file: the format trades size for uncompressed fidelity.

This conversion runs locally in your browser tab through Canvas or FFmpeg.wasm. The file is read from your device, decoded, re-encoded and handed back as a download; it is not uploaded to a conversion server. That keeps private recordings, client material and unreleased artwork off shared infrastructure.

After the download, play or open the result before deleting the original. Check the first and last seconds, confirm that transparency, rotation metadata or sample rate survived, and compare file sizes. If something looks wrong, retry with a higher quality setting rather than converting the output again.
