Select eligible WAV files
Add non-empty .wav files up to 100 MB each. The source must contain audio that host FFmpeg can read.
Server-backed WAV to FLAC conversion
Compress decoded WAV audio into a new FLAC file.
Upload eligible WAV files and download new audio-only FLAC files made from their first audio stream.

Supported files
WAV source, FLAC result.
WAVFLAC
Fileverses decodes a supported WAV source and encodes its first audio stream as a new audio-only FLAC file.
How it works
Queue WAV files, then download new FLAC audio.
Run the fixed conversion
Start the queue to process one file at a time with this route’s FLAC FFmpeg profile.
Check and download each FLAC
Review a completed result in compatible software, then download its separately named FLAC file.
Processing boundaries
Fixed FLAC output from the first audio stream.
The profile maps only the first audio stream, excludes video, removes source metadata and chapters, and uses FFmpeg’s FLAC encoder.
Convert WAV to FLACWAV files up to 100 MB
Only non-empty .wav uploads of 100 MB or less are accepted. Unsupported or unreadable audio sources cannot be converted.
New FLAC encoding
FLAC preserves the decoded input samples, but this route creates a new file rather than copying the source container, tags, or chapters. Size can vary.
First audio stream only
Only the first audio stream is mapped. Video, alternate tracks, subtitles, and attachments are excluded from this audio-only result.
No source tags or editing controls
Source metadata and chapters are removed. This route provides no trim, stream-selection, bitrate, sample-rate, channel, or quality controls.
WAV-to-FLAC details
Understand the file before you convert
Which WAV files can I upload?+−
Use non-empty .wav files up to 100 MB. Host FFmpeg must be able to read an audio stream in the source.
What does the downloaded FLAC contain?+−
A successful conversion contains a newly encoded, audio-only FLAC result from only the first audio stream using FLAC.
Can I add more than one file?+−
Yes. Add multiple eligible files. The browser submits each queue item sequentially and every completed result has a separate download.
Is WAV to FLAC a stream copy?+−
FLAC preserves the decoded input samples, but this route creates a new file rather than copying the source container, tags, or chapters. Size can vary.
Will source metadata or chapters remain?+−
No. The conversion profile removes source metadata and chapters. Alternate audio tracks, video, subtitles, and attachments are not included.
Can I change FLAC settings or trim the audio?+−
No. There are no trimming, stream-selection, bitrate, sample-rate, channel, or quality controls.
Does the preview guarantee the conversion will succeed?+−
No. Browser playback support and host FFmpeg readability are different checks. A file must be readable by FFmpeg for conversion, and playback depends on browser support.
