Upload FLAC sources
Add one or more non-empty .flac files up to 100 MB each. The source must contain audio that host FFmpeg can process.
Server-backed FLAC to WAV conversion
Create PCM WAV files from supported FLAC audio.
Choose FLAC files up to 100 MB and Fileverses will make separately downloadable, audio-only WAV results from the first audio stream.

Supported files
FLAC in, uncompressed PCM WAV out.
FLACWAV
Use this converter when a destination asks for WAV. Fileverses decodes the source and writes a new signed 16-bit PCM WAV file rather than repackaging FLAC bytes.
How it works
Make a WAV handoff from each eligible FLAC source.
Create signed 16-bit PCM WAV
Start the queue to decode the first audio stream and write a new pcm_s16le WAV with the route's fixed server-side profile.
Validate and download
Open a completed WAV in compatible software if required, then download each separately named output file.
WAV output facts
A new fixed PCM WAV, with no size promise.
The profile maps only the first audio stream, removes source metadata and chapters, excludes video, and encodes pcm_s16le. Uncompressed WAV output can be much larger than its FLAC source.
Convert FLAC to WAVOnly .flac uploads are accepted
Use non-empty FLAC files no larger than 100 MB. A file also needs a readable audio stream; a renamed or unreadable upload will fail conversion.
Fixed PCM signed 16-bit output
The WAV result is newly encoded as pcm_s16le from the first audio stream. It is not a FLAC stream copy and this route does not expose bit-depth or other PCM settings.
WAV can be larger
Because this WAV output is uncompressed PCM, it may be substantially larger than the FLAC source. No output-size or destination-compatibility guarantee is made.
No metadata retention or editing
The profile excludes video and removes source metadata and chapters. It does not offer trimming, alternate-stream selection, channel, sample-rate, bitrate, or quality controls.
FLAC-to-WAV details
Understand this PCM export
What codec does the FLAC to WAV converter use?+−
It creates audio-only WAV output with signed 16-bit PCM (pcm_s16le) from the first audio stream in a supported FLAC source.
Will a WAV download be smaller than FLAC?+−
Usually not a safe expectation. The route writes uncompressed PCM WAV, so the output can be much larger than the compressed FLAC input.
Can WAV restore information that FLAC does not contain?+−
No. The converter makes a new PCM representation of the decoded source. It does not recover missing detail, source history, metadata, or additional tracks.
What FLAC files can I upload?+−
This route accepts non-empty .flac files of up to 100 MB each, provided host FFmpeg can read an audio stream from the upload.
Does the WAV keep chapters, tags, or video?+−
No. The route maps the first audio stream only, excludes video, and removes source metadata and chapters before writing the WAV.
Can I control sample rate, channels, or bit depth?+−
No. FLAC to WAV uses a fixed signed 16-bit PCM profile. There are no controls for trimming, stream selection, sample rate, channel layout, bitrate, quality, or bit depth.
Can I convert several files in one session?+−
Yes. Add several eligible FLAC files to the queue. The browser submits files one at a time and conversion runs sequentially, so each successful source receives an individual WAV download.
