WAV to FLAC Converter
Store decoded WAV audio in a lossless compressed format. Sample-rate or channel changes still alter the signal, so retain the original when exact preservation matters.

How to convert WAV to FLAC online
- Select a supported WAV file from your device and check its detected type and size.
- Open Settings for the selected file to review sample rate (hz), audio channels. Leave the displayed defaults if they match your needs.
- Choose Convert and wait for the result. A queued job is waiting for a processing slot; a processing job is being handled.
- Download the result and open it in the application where you will use it. Keep the original and remove the server copy when finished.
What you will download
One audio file using FLAC, with the selected sample rate and channels. Defaults: 44,100 Hz and stereo. Metadata and cover art are removed.
Route-specific checks
Choose WAV to FLAC when lossless compression is useful for storage or transfer. FLAC preserves the decoded samples produced by the selected rate and channel settings, but those settings can still alter the original. Verify the archive with the intended player and retain the source WAV.
Available settings
- Sample rate (Hz)
- 22050, 44100, 48000; default 44100.
- Audio channels
- Mono (1 channel), Stereo (2 channels); default Stereo (2 channels).
Understand your file formats
- WAV is an audio container commonly used for uncompressed PCM sound.
- FLAC is a lossless compressed audio format.
WAV vs FLAC: what changes?
- Use WAV for editing and uncompressed PCM delivery where larger files are acceptable.
- Use FLAC when you want lossless compressed audio and the destination application supports it.
Technical format comparison: WAV vs FLAC
These properties describe the formats and the behavior implemented by this route. They are a decision aid, not a promise that two applications render every file identically.
| Format or operation | Format category | Compression behavior | Transparency support | Multi-page or animation behavior in ConverterZap | Typical best use |
|---|---|---|---|---|---|
| WAV | Audio container | Signed 16-bit PCM output; uncompressed | Not applicable | One audio stream; selected sample rate/channels | Use WAV for editing and uncompressed PCM delivery where larger files are acceptable. |
| FLAC | Audio stream/container | Lossless audio compression | Not applicable | One audio stream; selected sample rate/channels | Use FLAC when you want lossless compressed audio and the destination application supports it. |

About your output
Uncompressed WAV can be much larger than a compressed source. FLAC preserves the decoded audio but cannot undo losses already present in a lossy source. Up to 30 minutes. Metadata and cover art are removed. Output uses the selected sample rate and channels. MP3, AAC/M4A and Vorbis/OGG are lossy; a lossless output cannot restore information already lost. FLAC encoding is lossless, but resampling or changing channels can alter the decoded source audio.
Questions about WAV to FLAC
Is WAV to FLAC always a bit-for-bit preservation of my recording?
No. FLAC compression is lossless, but this tool applies the sample rate and channels shown in Settings. These can change a source recorded with different settings. Keep the original for archival use.
What happens to the WAV stream settings?
The first audio stream is decoded and written as FLAC with the selected sample rate and channel count. Metadata and cover art are removed, and a lossy source cannot regain discarded detail.
Which real-world check matters before I share this FLAC file?
Open the downloaded result in the application that will receive it and check the behavior described in the limits: Up to 30 minutes. Metadata and cover art are removed. Output uses the selected sample rate and channels. MP3, AAC/M4A and Vorbis/OGG are lossy; a lossless output cannot restore information already lost. FLAC encoding is lossless, but resampling or changing channels can alter the decoded source audio.
