Convert FLAC to WAV. Verify the samples.
Decode supported short FLAC files to PCM WAV locally. The converter checks the decoded samples against the FLAC’s embedded checksum before offering a download.
Convert FLAC to WAV
Free · localChoose a native FLAC file. No audio upload or account required.
Supports native FLAC with mono or stereo 8-, 16- or 24-bit audio at 8–192 kHz. Input and output must each fit 50 MiB; input must be no longer than five minutes. An embedded audio checksum is required and must match the decoded samples. FLAC metadata and artwork are not copied. Browser playback may not support every resulting WAV.

How to convert FLAC to WAV
- 01 / OPEN
Choose a native FLAC
Select a mono or stereo .flac with 8-, 16- or 24-bit audio at 8–192 kHz. Input and output must each fit 50 MiB, and the recording must be no longer than five minutes.
- 02 / CONVERT
Decode and verify
The browser decodes the audio locally and compares reconstructed PCM samples with the FLAC’s embedded checksum. If the checksum is missing or does not match, no WAV is offered.
- 03 / CHECK
Download the WAV
Download the verified PCM WAV and open it in your editor. Preview support varies by browser and format. Keep the original if you need its tags or artwork.
Understanding the result
Is FLAC to WAV lossless?
FLAC stores compressed audio without discarding PCM samples. For files this converter accepts, the exported WAV retains the decoded sample values, sample rate, bit depth, frame count and channel layout. The WAV is usually larger because its PCM audio is uncompressed. The file headers differ even when the audio samples match.
The embedded checksum checks the reconstructed samples against the checksum stored in the FLAC; it does not establish the recording’s provenance or recover detail lost before the FLAC was created. Tags, artwork and other metadata are not copied. Compare formats in our FLAC versus WAV guide.
The WAV option on our FLAC to MP3 converter makes a resampled 16-bit working copy; this page preserves supported source samples instead.
Troubleshooting
Supported files and limitations
This tool accepts native FLAC with a nonzero embedded audio checksum, known duration, mono or stereo layout and 8-, 16- or 24-bit audio. It rejects unsupported files, checksum mismatches and results over the limits. Use a desktop converter for Ogg FLAC, multichannel or 32-bit audio, files without a checksum, and longer recordings.
Use the WAV file inspector to check the saved file’s stored format. The inspector does not compare samples. Conversion uses the open-source wasm-audio-decoders FLAC decoder and noble-hashes checksum implementation.
A few useful answers
Free FLAC to WAV converter questions
How do I convert FLAC to WAV?
Choose a supported native FLAC, convert it locally, then download the WAV if the embedded checksum matches. Keep the original if you need its metadata.
Is FLAC to WAV lossless?
For accepted files, the WAV preserves the decoded sample values, sample rate, bit depth, frame count and channel layout. The embedded FLAC checksum must match. Metadata is not copied and previously lost detail cannot be recovered.
Is my audio uploaded?
No. Conversion runs in your browser; download the result before leaving the page.
Which FLAC files are supported?
Native FLAC with a known duration and embedded checksum, mono or stereo, 8-, 16- or 24-bit, and 8–192 kHz. Input and output must each fit 50 MiB and the recording must be at most five minutes. Some files may fail verification.
Why is the WAV larger?
FLAC compresses audio without discarding samples, while PCM WAV stores uncompressed audio. The size difference does not imply better audio quality.
